Many of the charts below are not currently being updated.

See current trends for the things I update retularly.

In May 2023 the CDC switched from counting cases to counting hospitalizations.
As of December 2023 the California department of health stopped reporting county data.
As of December 2023 US county hospitalization rates are still being reported in the CDC's map.
As of January 2024 I couldn't find any data from the WHO that included cases, hospitalizations or deaths for the US, Europe and South America.

The bottom Line - Deaths:
As of December 2023 the official reported world death count from COVID-19 is 7 million.
As of January 2023, taking into account likely COVID induced deaths via excess deaths (all deaths before COVID-19 vs deaths during COVID-19) suggests the pandemic has caused between 16 and 28.2 million deaths (0.2% - 0.4% of the world population).
So it is much lower than the 1918 flu where there were somewhere between 17 and 50 million deaths (0.9% - 2.8% of the population).

Note: As of April 2023 many sources are only updating every several weeks.
As of August 7, 2023 the Americas Region stopped reporting COVID-19 stats to the WHO


I started this page when the media was reporting the total number of new cases. 1,000 new cases in California is not as significant as 1,000 new cases in Nevada.
I wanted to know the probability of running into someone with COVID in the grocery store, so started listing deaths per 100,000 and deaths which at the beginning were more accurate than new cases.
InIn May 2023 rates had dropped to around 2% of their highs and because with vaccinations symptoms were so mild that many cases were not being counted.
Hospitalizations, which were more accurate, were about 4% of their previous highs.
The CDC and many others made hospitalizations the statistic of choice, so many of the charts here were not being updated.
The best statistics were test positivity and wastewater testing which showed trends but couldn't be correlated with actual number of cases. There is more detailed information about the US and North Central California where most of my friends and family live.

We are tracking 56 countries of interest based on size (generally population > 5 M) tourism, economy (G20), relationships with the U.S., and tracked by the The World Health Organization (WHO) out of 230 countries and territories tracked by worldmeter and 218 in Our World in Data and worldvision. The U.N. lists 193 countries plus 3 non members who have nation-hood rights (Vatican City, Taiwan, and Kosovo)
There are many smaller countries with higher rates.

Surges

In May 2023 infection rates had dropped to around 2% of their highs and because with vaccinations symptoms were so mild that many cases were not being counted.
The CDC and many others have now made hospitalizations the statistic of choice.

We are seeing summer surge for the 3rd year, but of the 56 countries we are monitoring only South Korea, New Zealand Australia had more than 30 new cases per million at the end of July. (At the peak of the outbreak at the beginning of 2022, there were a dozen countries with an average of more than 1,000 new cases per million per day)

This can be attributed to:

There have been Winter surges regularly too.
Partly because of the same reason -- People are staying inside because of the weather,
and new variants were emerging.

Updated Mondays and Thursdays


The hospitalizations on Jan 1, 2024 were 80% of those a year earlier.

Note: The actual infection rate is probably closer to the Omicron hight. Fewer people are getting hospitalized because of mild symptoms due to vaccinations and immunity from exposure.

US County hospitalization rates:

California
The January 1st rate was 72% of the high of 22.3 on Jan 6 2022.

Some Counties I watch:
Note: As of December 5 the California Department of Health has stopped publishing county data.
The LA Times has county data at Tracking COVID-19 in California, You need to search for counties individually.
Note: I think the number below is total people in the hospital because of COVID not new people per day, so it is higher than the table below.

Total cases now is probably a higher percent of the peak than hospitalizations because more people have immunity from vaccines or esposure, so fewer of infected people are going to the hospital.

† Sutter Co. does not report hospitalizations to the California Dept. of Health.


As of Dec 1 the California Department of Health is no longer publishing county charts.
Wastewater testing is the only current tracking charts I've found. Unfortunalty the're not available at the county level. Here are some for the Sacramento Area and Bay ares.

On January 5th Yolo Co. Health asked the Davis library staff to start waring masks.



Yolo Co.
As of Dec 1 the California Department of Health is no longer doing these graphs.
See the LA Times, for a day at a time update. You have to search for each county.
Last published chart:

The California department of health shows the Yolo Co. rate on Sept. 2 of 1.22 was 8 times higher than the rate on July 29 of 0.18, and was higher than the peak rate of 1.35 in January 2021 (The alpha peak). Yolo County redirects you to the state data.

Davis:
This chart seems to be updated several times a week, but can be 4 or 6 days old.

The rate on Sept 6 was 6 times higher than the low rate on June 19 .

San Mateo Co.

Placer Co

See the LA Times, for a day at a time update.
Last published chart:

Their rate of 3.2 per 100,000 is more than 3 times other counties in the area, California and the U.S. . I think they must be counting all hospitalizations not just COVID.

The rate on Sep 2 of2.5 per 100,000 per day was 2 times the rate on July 4 of 1.31 per 100,000 on sept. 2, but still 27% of the peak rate of 9.1 in January 2022 (Omicron).

World:
Most places have stopped reporting new cases. The CDC has transitioned to hospitalizations as the primary measure, but the WHO still reports new cases .
The WHO dashboard shows a 50% increase global new cases in the month ended August 14 compared to the previous month, but it was 1.5% of the global highs.

New variant:
Aug 23 - A new variant, BA.2.86 (Pirola), with 36 mutations of the BA2 strain has been detected in Virginia, Michigan and Ohio, the UK, Israel, Denmark and South Africa.
BA.2.86's mutations include changes at key parts of the virus that could help the variant dodge the body's immune defenses from prior infections or vaccinations.

- North America includes Central America, the Caribbean and Greenland.
* The Omicron peak was on or before Jan 31, 2022 for the above.
Omicron infects different cells in the upper respiratory tract rather than in the lungs, which makes it more transmissible but less severe than the previous variants.
The death rates were slightly lower even though the infection rates 4 or more times higher, so the death per infection were about ¼ the rate of previous variants.

The WHO Western Pacific Region Oceania, notably New Zealand and Australia plus smaller island countries had the highest case rates in 2022, but they had the lowest case rates in 2020 and 2021. Other countries in the WHO's Western Pacific Region, South Korea, Japan, Taiwan had a similar pattern.
But they had the lowest cumulative death rates over the life of the pandemic, < 800 per million, compared to the US, Europe and South America which were mostly > 2,000.
See Omicron spread below.

As of January 2024 I couldn't find any data from the WHO that included cases, hospitalizations or deaths for the US, Europe and South america.

The US cumulative death rate in May 2023 was 20% higher than Europe.
The US is 4% of the world's population but as of April 15, 2023 the US had 16% of world deaths.

By February 2023 about 70% of Americans were completely vaccinated while around 80% of Europeans were.

China seems to have stopped reporting, but they had severely undercounted in the past.
Russia reports 2,679 cumulative deaths per Million, but they have undercounted according to studies.

Number's are 7-day averages.
1,000 deaths per million is 0.1% of the population.
The numbers are significantly undercounted. The latest WHO report in May 2022 says there have been around 15 million cumulative cases way more that the 6 million reported.
An April 2022 CDC report showed that about 60% of Americans had been infected, while official cumulative case counts were 27%.
Wastewater counts in the summer of 2020 indicate actual case counts are 3-5 times higher than reported.
The general explination for this is:
1. More asymptomatic cases which are not reported.
2. People doing self testing with mild symptoms which are not reported.
See Data Accuracy

Asia and Africa account for 76% of the world population but only 23% of the deaths.
Oceana has one of the highest infection rates as of January 2022, because of an outbreak in Australia, but over the course of the virus they have the lowest total death rate, 148 per million, of any continent.

Chart with all countries listed above

There are multiple sources of data giving information about the number of SARS-CoV-2 infections in the population, but all have major drawbacks, including biases and delayed reporting. For example, the number of confirmed cases largely underestimates the number of infections, and deaths lag infections substantially, while test positivity rates tend to greatly overestimate prevalence.

* Arizona and New Mexico have the highest percentage of Native Americans.
Mortality rates for Native Americans were 2.8 times as high as that for the white's according to a December, 2021 Princeton study.
Arizona - Native Americans make up 4.6% of Arizona's population, but 16% of those who have died of COVID-19.
If you discount the Native American numbers Arizona's death rate would be 4,040 which would put them at #13.

New Mexico - Native Americans make up 11% of New Mexico's population, but 50% of those who have died of COVID-19.
If you discount the Native American numbers New Mexico's death rate would be 2,463 which would it at #42.

† The tri-state area, New York, New Jersey and Connecticut, death rates were initially the highest.
New York, New Jersey and Connecticut were the first states to be hit hard in the Spring of 2020 with case rates 3-5 times higher than the national average. Hospitals were still learning how to treat it.
And they had increased exposure because of international travel to New York City and New York City commuters in New Jersey and Connecticut.

By August 2021 after 50% of the country had been vaccinated, New York, New Jersey and Connecticut's cumulative death rates were still in the top 10 states for death rates, but they were also in the top 10 for highest vaccination rates.
I spent 40 years in New Jersey and have a lot of friends there. They are generally very health conscious, so this bothered me and I looked a little closer.
If you look at death rates from September 2021 (after a 50% rollout of vaccinations) to October 2023 they have the lowest death rates.

Even though the second period included the Omicron outbreak in January 2022 with the highest case rate, 5 times previous variants, the death rates were lower because of:
1. Omicron was less severe (virulent)
2. Vaccinations

Death rate - vaccination rate chart
Not: The death rate values here are for Aug '21 , (when vaccination rates hit 50%) - Oct '23, are not the same as the values in the death rate table above which are all deaths over the course of the pandemic.

Chart Data

Deaths as a function of % voting for Trump in 2020

There is a stronger correlation here than with vaccination rate
Probably because most Trump voters have 2 bad habits: 1. Not wearing masks in addition to 2. Not getting vaccinated.
The median for Biden voters is 1320 deaths per million; for Trump voters is 1890 deaths per million.
i.e. a 43% higher death rate for Trump voters.
With 332 million people in the US about half following Trump guidelines for COVID safety that is 94 million unnecessary deaths.
This is a simple analysis. Other variables should be considered. e.g. Many more Trump voters live in rural areas with lower healthcare availability.

Omicron Spread:

I started this chart as the Omicron surge was growing to show how countries were following a similar pattern.
I kept it because they were generally indicative of Europe and North America.
I added New Zealand and Taiwan because they were traditionally the lowest rates in the world and were having a surge in March and May after the world Omicron variant surge in January.
New Zealand, Japan, S Korea and Taiwan which had been doing much better with cumulative death rates of less than 600 per million while Europe and North America were 4 times higher around 2,500 deaths per million.
Omicron infects different cells in the upper respiratory tract rather than in the lungs, which makes it more transmissible but less severe than the previous variants.

WHO's Western Pacific Region rates have been very low until Omicron. Their cumulative death rates over COVID have ranged from 460 - 650 per million, while the US and European cumulative death rates have ranged from 2,000 to 3,000.
My theory is that the western countries have gotten close the herd immunity (A CDC report in April 2022 says that almost 60% of the U.S. has been infected.) which kept their new infection rates down.


See WHO Regions below

U.S.: 106,376,396 cases; 32,146 cases per 100K

30,000 out of 100,000 is 30%.
CDC's Morbidity and Mortality Weekly Report, April 29, 2022 showed that almost 60% of people in the US had been affected.
Other studies by the WHO and wastewater testing showed similar undercounting.
Undercounting got worse during 2022 with vaccines resulting in asymptomatic cases and people doing self-testing.
See Data Accuracy.

China
Note: China numbers are low in the above chart and most public data because of undercounting in cases and deaths.

Variants
Aug 23 - A new variant, BA.2.86 (Pirola), with 36 mutations of the BA2 strain has been detected in Virginia, Michigan and Ohio, the UK, Israel, Denmark and South Africa.
There is a concern it could dodge the body's immune defenses from prior infections or vaccinations.

Davis 212† 4
* California stoped reporting new cases in May

See more detail at corona-detail

† Davis typically had one of the 2 lowest rates of new infections in the 10 states and 12 counties in California that I follow. But in January 7 2022 it had the 2nd highest rate. I attribute that to 30,000 undergraduate students at UC Davis (30% of the population) who returned to Davis after the Christmas Hollidays, where they were exposed in family gatherings and mass transit on the trip back.

The Bay Area in California which has had the second lowest rate of California's 5 regions behind Northern California and in the Fall of 2022 it had the highest rate. See Bay Area vs other CA regions.
My theory is that as of August 2022 the Bay area has had the lowest death rate, less than half the other regions, so the population does not have a built up immunity from prior infections.

City Wastewater Data

Historic Wastewater Testing - Healthy Davis Together
Comparison of the Healthy Davis wastewater testing with CA cepartment of health results from the Omicron outbreak to November 2022.
The purpose is to show than many cases were not reported after the Omicon rates dropped.
Note: The Yolo Co. Dept. of Health stopped reporting data for Davis, so we have a little apples vs oranges situation, but Davis numbers tracked Yolo Co. numbers but were a little lower.


In January, Yolo County had 248 new cases per 100,000 reported and Davis had 212. Davis rates have traditionally been lower than Yolo County.
On Nov 7th Yolo County had 8 new cases reported per 100,000, 3% of the peak, but Davis wastewater counts were 23% of the peak.
So about 13% of cases are being reported.
The general explination for this is:
1. More asymptomatic cases which are not reported.
2. People doing self testing with mild symptoms which are not reported.

This along with an April, 2022 CDC report indicated that almost 60% of the U.S. population has been infected. means that as of June only about 10% of infections were being counted.

Although wastewater indicates a high level of infection at the end of August, Yolo county hospitalizations are 20% of what they were in January. California hospitalizations were 25% of January's.

Note: Wastewater results tend to be more variable than reported cases. See the national wastewater results above.

Arizona - Native Americans make up 4.6% of Arizona's population, but 16% of those who have died of COVID-19.
If you discount the Native American numbers Arizona's death rate would be 4,040 which would put them at #13.

New Mexico - Native Americans make up 11% of New Mexico's population, but 50% of those who have died of COVID-19.

Regional Cumulative Death Rates

- North America includes Central America, the Caribbean and Greenland.

- Oceania [½ of 1% of the world population] includes Australia (59% of the population), Melanesia (Papua New Guinea, Fiji, Solomon Islands, ...), Micronesia (Marshal Islands, ...), and Polynesia (New Zealand, Samoa, ... )

China
In early December 2022, China suddenly reversed its "zero Covid" policy. That set off a wave of infections that has swept across the nation, overwhelming hospitals and funeral parlors.


They stoped reporting in January, so we don't know the current status.

With China's population of 1.45 billion, 9,300 cases on January 6 is 6 cases per million.
See The WHO China COVID Dashboard which says there were 34,610 new cases (28 per million) on January 6.
I don't know why the number of cases reported on worldmeter and the cases per million on Our World in Data are lower than the WHO numbers.
28 new cases per million is relatively low, which doesn't account for the large number of hospitalizations. The US had 154 new cases per day per million on Jan 6 and Europe had 130.
The World Health Organization (WHO) has criticized China for not being forthcoming with statistics and not following WHO guidelines for counting deaths since the beginning of COVIE-19 .
China's population is 37% rural, which might account for some lower averages, but not that large a difference. I could not find any data for infection rates in urban places like Shanghai, Wuhan and Bejing.
See China Estimates Covid Surge Is Infecting 37 Million People a Day at Bloomberg December 23rd.

China's current wave appears to be dominated by two main Omicron subvariants already circulating in other parts of the world: BA.5.2 and BF.7 (which is actually short for BA.5.2.1.7). Both BA.5.2 and BF.7 are from the same Omicron lineage, and have been bubbling along in North America, Europe, other parts of Asia and Australia since mid-to-late 2022.
Local reports indicate that BF.7 is the dominant subvariant currently circulating inside China, with a shorter incubation period, faster transmission rate, and stronger resistance to immunity than previous strains the country has seen.
In the US, BF.7 has dropped from 7% of cases in October 2022 to 2.2% in January 2023.

Czechia 3,242  Romania  3,041  Brazil  2,874

‡ If you adjust for the undercounting in Mexico and Russia their rates would be:
Mexico 4,862 deaths per million
Russia 8,358 deaths per million

Regional Death Rates: S. America 2,732; N. America 1,999; Europe 1,968
Asia, Africa and Oceana all have less than 300 deaths per million.
New Zealand, Australia, South Korea and Taiwan all had less than 100 deaths per million.

A Wall Street Journal Report in July 2021 says that the actual death count in India is is between 3.4 and 4.7 million, 10 times higher than the 400,000 reported.
With a population of 1.4 billion that would give India over 3,000 deaths per million and raise Asia's deaths per Million to over 1,000.


Because Asia and Africa account for 76% of the world population but only 23% of the deaths we dont compute a world rate. There are smaller countries in Asia and Africa who's infection and death rates are similar to other developed countries.

Data Accuracy

The most complete study to date was released by the World Health Organization (WHO) on May 5th 2022
A World Health Organization (WHO) study shows that the full death toll associated directly or indirectly with the COVID-19 pandemic (described as excess mortality) between 1 January 2020 and 31 December 2021 was approximately 14.9 million, more than double the official death toll of 6 million.
They measured the increase in the death toll, which was COVID-19 directly (due to the disease) or indirectly (due to the pandemics impact on health systems and society). e.g. lack of access to ERs and intensive care.

Excess mortality includes deaths associated with COVID-19 directly (due to the disease) or indirectly (due to the pandemics impact on health systems and society).
Most of the excess deaths (84%) are concentrated in South-East Asia, Europe, and the Americas.
The production of these estimates is a result of a global collaboration supported by the work of the Technical Advisory Group for COVID-19 Mortality Assessment and country consultations. with over 30 researchers from around the world.

Previous Studies:

Almost 60% of U.S. Has Been Infected by COVID-19, CDC Says;
Researchers looked at the presence of coronavirus antibodies to estimate the rate of infection.
During September 2021February 2022, a convenience sample of blood specimens submitted for clinical testing was analyzed every 4 weeks for anti-N antibodies. the median sample size per 4-week period was 73,869 .
It indicated 57.7% of Americans had been infected.
Official infections reported were 80.5 Million or 24% of the population, i.e. only 42% of infections were reported.
See WebMD
The report was published in the CDC's Morbidity and Mortality Weekly Report, April 29, 2022

Davis, CA Wastewater testing indicates that in June 2022 only 20% of cases were reported compared to January 2022.
The general explination for this is:
1. More asymptomatic cases which are not reported.
2. People doing self testing with mild symptoms which are not reported.

1,000 deaths per 100,000 is 1% of the population.

A Wall Street Journal Report in July 2021 says that the actual death count in India is is between 3.4 and 4.7 million, 10 times higher than the 400,000 reported.
With a population of 1.4 billion that would give India over 3,000 deaths per million and raise Asia's deaths per Million to over 1,000.

"Estimating excess mortality due to the COVID-19 Pandemic a study by Researchers at the University of Washingtons Institute of Health Metrics published in the Lancet March 10, 2022 . They found,
"Although reported COVID-19 deaths between Jan 1, 2020, and Dec 31, 2021, totalled 5.94 million worldwide, we estimate that 18.2 million (95% uncertainty interval) people died worldwide because of the COVID-19 pandemic (as measured by excess mortality) over that period. The global all-age rate of excess mortality due to the COVID-19 pandemic was 120.3 deaths per 100000 of the population, and excess mortality rate exceeded 300 deaths per 100,000 of the population in 21 countries. The number of excess deaths due to COVID-19 was largest in the regions of south Asia, north Africa and the Middle East, and eastern Europe. At the country level, the highest numbers of cumulative excess deaths due to COVID-19 were estimated in India (4.07 million), the USA (1.13 million ), Russia (1.07 million ), Mexico (798), Brazil (792000), Indonesia 736,000 , and Pakistan 664,000"

At Estimating global, regional, and national daily and cumulative infections with SARS-CoV-2 through Nov 14, 2021: a statistical analysis - The Lancet, Published in April 2022,
They looked at global data from the start of the Pandemic to November 2021 with information from The Institute for Health Metrics and Evaluation (IHME) and others, they estimate that over 40% of the global population was infected at least once by Nov 14, 2021.

Dr Scott Gottlieb, former FDA commissioner, said on "Face the Nation", April 2022,
"We are probably only picking up 1 in 7 or 8 infections, because people are using home tests which never get reported."

"Covid death rates were 26 percent higher in areas where voters lean conservative."

The 10 counties who voted for Biden in 2020 averaged a total of 1,203 deaths per million over the course of the virus as of March 12, 2022 compared to the 2 counties who voted for Trump which average averaged 1,870 deaths per million (55% higher).

* Sierra County had only 12 new cases from Feb 15, 2021 to July 4, 2021 with a 7 day average of close to 0.
At the beginning of july, the beginning of September and middle of October they had an outbreak raising the 7-day average to 3 cases per day making the rate per 100,000 100 cases per day.
With a population of just over 3,000 a small outbreak results in a high rate (new cases per 100,000)
But their cumulative death rate since the beginning of the pandemic is the lowest of all counties represented here.

New Cases per day per 100,000
For reference, in January California had over 100 new cases per day per 100,000 and Los Angeles Co was over 150.

39.3% of the world population has received at least one dose of a COVID-19 vaccine.
Only 1.6% of people in low-income countries have received at least one dose.

Those who are vaccinated are about six times less likely to contract the virus and 14 times less likely to die from it.

Note: A report published by Arvind Subramanian, the Indian governments former chief economic advisor, and two other researchers at the Center for Global Development and Harvard University said the actual number of deaths in India was likely between 3 million to 4.7 million between January 2020 and June 2021. This is 10 times higher than the 400,000 reported, so would put India at the top of the list of death rates.

Test Positivity Rate
Experts advise looking at three measurements together: number of cases, case positivity rates and number of deaths to understand what is going on.
Test Positivity Rate is important because a high positivity rate probably means that the case count is low. See Positivity Rate.
WHO guidelines want it to be below 5%. When a positivity rate is higher, epidemiologists start worrying that means only sicker people have access to tests and a city or region is missing mild or asymptomatic cases.

CDC COVID Data Tracker

COVID was the leading cause of death in the United States in January 2021:

Provisional Death Counts for Coronavirus Disease 2019 (COVID-19) | CDC
The average percent of COVID-19 deaths from Mar. 21, 2020 to May 22, 2021 was 14.4%.
That made it #3 behind heart disease (28%) and cancer (25%) as cause of death.
Note: These are the 2019 rates for heart disease and cancer.
They may be lower in 2020 because people weakened from these diseases may have succumbed to COVID first. I don't know how the CDC counts someone who dies of heart disease because of stress from COVID.

The epicenters keeps changing:
The first confirmed case relating to the COVID-19 pandemic in the United States was announced by the state of Washington on January 21, 2020. Washington made the first announcement of a death from the disease in the U.S. on February 29 Washington had the highest absolute number of confirmed cases (500) and the highest number per capita (7 cases per 100,000)of any state in the country, until it was surpassed by New York state on April 10.

I moved back to California from New Jersey a couple of years ago. In April my friends in New Jersey had 10 times the chance of encountering a person with COVID-19 than I did in California. In July the numbers have flipped with California having 6 times and Florida 12 times the incidence of NJ.
By the end of November the average rate for the whole country was 5 times higher than it was in April.
In July 2020 because of their new case rates and population, Florida, Texas and California accounted for 19% of all new cases in the world and more than a third of the new cases in the U.S. with a total of 27,574 new cases per day recorded.
Case rates in those states droped by 2/3 in September.
in January 2021 the U.S. accounted for 34% of all new cases in the world.
In April 2021 the world hit a record of 823,439 new cases, 41% from India.

Bay Area Region vs Other Regions

A LA Times report said that in January 2022 the death rate in southern California was 3 times higher than the Bay Area.

The Bay Area in California has traditionally had the second lowest rate of California's 5 regions behind the Northern California region and was usually lower than the State rate. As of May 2022 the Bay Area cumulative death rate over the life of COVID was about half the other regions. See above.
In May 2022 the Bay Area had the highest rate.

I had a theory that the regions which had higher rates in the past have developed a herd immunity. However, that has not held up in the last half of 2022 where the Bay Area and Southern California have been trading off for the highest rate.
My new theory is that areas with the highest inter-state and international visitors are affected first. That was the case in the North East states also.

The CDC sampled blood for antibodies from September 2021 to February 2022 and concluded that almost 60% of Americans had been infected, which is much higher than the 24% of cases reported, so we would be approaching heard immunity numbers. However the frequent mutations in the omicron variant messes up the heard immunity theory.

Holiday surge: 2020

The increase of infections after holidays confirms the dangers of personal social gatherings.
There is a drop in infections durring the holidays because of reduced testing. Johns Hopkins University reported a high of more than 2 million tests a few days before Thanksgiving as people prepared to travel, but that number had dropped to less than 1.2 million tests on Thanksgiving Day.

  • November 2023- A new strain, HV.1, was responsible for about a quarter of new coronavirus cases as of late October, rising to the highest prevalence of any strain circulating in the U.S.
    The strain is still a subvariant of omicron – as is every strain that’s in circulation. It’s a descendent of EG.5 (eris), which is the second most common variant in the U.S. at nearly 22% ,
    Given how similar HV.1 is to EG.5, the updated coronavirus vaccines are expected to work on the new strain.
  • October - I added a vaccination vs death rate chart.
  • Sept 11 - The Food and Drug Administration approved new COVID boosters. The CDC recommends them for everyone aged 6 and up. They should be available this week.
    The new boosters are a much closer match to currently circulating variants than prior vaccines, say federal health officials. They're updated versions of the existing Moderna and Pfizer-BioNTech vaccines and have been formulated to target a relatively recent omicron subvariant called XBB.
    The CDC says the updated vaccines should work against currently circulating variants of the SARS-CoV-2 virus—many of which are descended from or related to the XBB strain. The two strains, EG.5 and XBB.1.5, are not identical, but they're pretty close to XBB.
    The omicron variant is like a big family, and its known family members – BA.2, BA.2.86 and XBB.1.5 – are all branches – or lineages and sublineages – on the same tree.
  • Sept 5 - Research has shown that current vaccines are efective against BA.2.86 (Pirola).
    It has been detected in Michigan, New York, Ohio, Texas and Virginia.
  • Aug 23 - A new variant, BA.2.86 (Pirola), with 36 mutations of the BA2 strain has been detected in Virginia, Michigan and Ohio, the UK, Israel, Denmark and South Africa.
    BA.2.86's mutations include changes at key parts of the virus that could help the variant dodge the body's immune defenses from prior infections or vaccinations.
  • August 20 - COVID-19 is still a pandemic according to the World Health Organization.
    Average U.S. Hospital admissions went up 3 1/2 times from 0.27 per 100,000 on June 24 to 0.74 per 100,000 on Aug 26. This is still only 12% of the highest rate of 602 per 100,000 in the January 2022 Omicron Surge.
    The hospitalizations in Jan 1, 2024 were 80% of those a year earlier.
    There also hasn’t been an increase in Covid-related deaths, which tends to lag behind a rise in hospitalizations.
    Currently EG.5 is the dominant strain with 20% of cases.
    See Surges
  • May 15 - Most places stopped counting new cases. The CDC counts hopsitalizations; California counts Test positivity rate.
  • May 5 - WHO declares an end to the COVID-19 global health emergency. Three years and 2 months after it was declared a Pandemic.
    They have recorded close to 7 million deaths from COVID-19, though the real death toll from the pandemic may be three times that.
    The death rate in the US for COVID-19 was 0.3% of the population.
    The death rate for the 1918 FLu (H1N1) was 0.7% of the population.
    See Pandemics
  • April 18 - CDC simplifies COVID-19 vaccine recommendations, allows older adults and immunocompromised adults to get second dose of the updated vaccine.
  • April 10 - The US ended the national emergency for Covid-19. It will not affect the end of the separate public health emergency scheduled for May 11.
    The national emergency allowed the government to take sweeping steps to respond to the virus and support the countrys economic, health and welfare systems.
    The WHO will decide whether to extend the "Public health emergency of international concern" (PHEIC) in its quarterly meeting at the end of April.

  • April 1 - Most major countries and regions now have < 10 new cases per 100,000 per day. However, New Zealand, South Korea and Australia have 15-30 new cases per 100K. In the first 2 years of the pandemic they have had much lower rates than the rest of the world and their cumulative death rate is less than half of the rest of the world.
  • Feb 15, 2023 We still have a pandemic. The XBB.1.5 variant is spreading. It accounts for 80% of new cases in the U.S. and is in 38 countries now. It is more contagious but appears to be less severe than previous strains.
    However, the infection rates have have gone back down to the October 2022 lows following the holiday surge.
    The WHO Pacific region (S. Korea, Japan, Taiwan, New Zealand, Australia) still has the highest infection rate, but they are down from their Summer-Fall 2022 highs.
    Weekly change in new cases is down in all WHO regions, Europe, Americas, Western Pacific, South-East Asia, Eastern Mediterranean, and Africa.
    Europe and South America show a slight increase in the last month at Our World in Data.
    China has stopped reporting, so we don't know the status of the surge there since they dropped their "Zero Covid" policy at the end of December 2022.
    The U.S. will end it's COVID-19 Public Health Emergency (PHE) and National Emergency on May 11, 2023.
  • Dec 31, 2022 A new variant XBB.1.5 now accounts for 28% of new cases in the US and is rising fast.
    XBB.1.5 seems to be more contagious. So far there is no indication it was more serious or harmful than previous Omicron variants.
    See US Variants below
  • Dec 25 2022- In early December, China suddenly reversed its "zero Covid" policy. That set off a wave of infections that has swept across the nation, overwhelming hospitals and funeral parlors.
    See China below .
  • Nov 11 2022- New cases in Japan have increased 66% and South Korea have increases 37% over the last 2 weeks.
  • Oct 29 - New variants BQ.1, BQ.1.1 and BA.4.6 now account for 37% of new cases in the U.S. BA.5 is still the most prominent variant.
    See US Variants below
    The U.S. COVID-19 public health emergency (PHE) declaration will end on May 11.
  • Oct 21 - A new variant, XBB, a descendant of two different BA.2 variants is emerging.
    XBB, in addition to competitor BQ.1.1, escape antibody immunity.
    XBB has been reported by 26 countries.
    Last week, Singapore's health ministry said its rise in cases over the past month is mainly due to the Omicron XBB subvariant.
    As of Oct 25th Singapores new cases were down 10% over the previous 2 weeks.
    See: Global COVID-19 cases down, but rising in Western Pacific | CIDRAP (Center for Infectious Disease Research and Policy)

    The european surge of BA.2.75 seems to have peaked.

  • Oct 1 - Europe is experience a new surge with a 33% increase in new cases in the last 2 weeks. This time the ongoing COVID-19 wave is being propelled by sub-lineages of the Omicron variant, notably BA.2.75 and BA.5, with each dominant sub-lineage of Omicron showing clear transmission advantages over the previously circulating viruses.
  • Sept 1 - The CDC and FDA authorize new Omicron BA.4 and BA.5 specific variants of COVID-19 booster vaccines from Moderna and Pfizer.
  • August 11 - The CDC loosens COVID guidance, because the majority of people have some imminity and are unlikely to become severely ill.

    August 5 - Despite all the news about a BA.5 surge most regions are now seing decreases in the new case rate. In the last 2 weeks the US new case rate dropped 20% and Europe dropped 30%. However case rates in the US are still 3 times what they were on Apr 1 and Europe is double what it was on June 1, still well below peaks in January.
    All world regions except Asia were down. In the US the Northeast, West and South were down, the Midwest was up slightly; California was down 24%; and all all California regions are down.
    US Wastewater Surveillance sites are also generally showing a decline.
  • July 5 - The BA.5 strain, the most contagious one so far, now accounts for more than 50% and BA.4 over 20% of cases in the U.S. according to the CDC. New case counts have not increased much but there is a rise in hospitalizations and test positivity rate. See U.S. data
    "BA.5 is able to evade previous immunity, said Dean Blumberg, chief of pediatric infectious diseases at UC Davis Childrens Hospital. So, breakthrough infections with people who had previous infections are common.
    Note: only a fraction of new cases are being reported. See below.
    David Montefiori, a professor at the Human Vaccine Institute at Duke University Medical Center, said " BA.4 and BA.5 havent been found to cause more severe disease.
    Rather, rises in hospitalizations observed in some places more likely have to do with fading vaccine protection."

    and Covid: Omicron subvariants BA.4 and BA.5 escape antibodies from vaccination and prior infection, studies suggest - CNN

  • June, 2022 - The CDC sampled blood for antibodies from September 2021 to February 2022 and concluded that almost 60% of Americans had been infected. Official counts showed only 24% infected, so only 43% were actually reported.

  • June 10 - U.S. drops Covid testing requirement for international travelers.

  • May 12 - The CDC's official death count from COVID hits 1 million. Other reports said it hit a million several weeks ago. The actual total is much highr.
    I compared the wastewater results for Davis, CA, with reported cases in January and August. It indicated about the same thing.
  • May 5, 2022 - New estimates from the World Health Organization (WHO) show that the full death toll associated directly or indirectly with the COVID-19 pandemic (described as excess mortality) between 1 January 2020 and 31 December 2021 was approximately 14.9 million, more than double the official death toll of 6 million.
    See Data Accuracy below.
  • May 2 - The BA.2.12.1 Omicron Variant is spreading. It already makes up nearly 60% of cases in the Northeast US , according to estimates by the CDC. BA.2.12.1 may be 20% to 30% more infectious than BA.2.

  • May 5, 2022 - The Bay Area in California which has had the second lowest rate of California's 5 regions behind Northern California and in the Fall of 2022 it had the highest rate. See Bay Area vs other CA regions.
    My theory is that as of August 2022 the Bay area has had the lowest death rate, less than half the other regions, so the population does not have a built up immunity from prior infections.

  • Apr 18, 2022 - Although cases continue to rise in the northeast and some other places, Dr Scott Gottlieb, former FDA commissioner and Dr Anthony Fauci do not think is the start of a major outbreak.
    A court case in Florida says the CDC cannot issue mask mandates for transportation.
    TSA says they will not enforce the mask mandate.

    Dr Scott Gottlieb, former FDA commissioner, said on "Face the Nation",
    "We are probably only picking up 1 in 7 or 8 infections, because people are using home tests which never get reported.

  • Apr 9 - The majority of US cases are the BA.2 variant. The only significant change in cases is a 60% increase in the Northeast over the last 3 weeks.

  • Mar 3 - The world death count hit 6 million
  • Feb 24, 2022 - The BA.2 variant of Omicron is about 30% more transmissible than the original Omicron variant, BA.1, and it is now causing about 1 in 5 Covid-19 cases worldwide.
    It has a low hospitalization rate like BA.1.
    WHO said "They are monitoring countries that have detected BA.2, but so far the subvariant hasnt caused a fresh surge in cases."" Globally, Covid cases have plunged 21% over the past week.

  • 2021
  • Nov 26, 2021 - South Africa announced a new COVID variant, Omicron
    It infects different cells in the upper respiratory tract rather than in the lungs, which makes it more transmissible but less severe than the previous variants.

    As of December 4th The Omicron variant had been detected in at least 38 countries but no deaths have yet been reported.

    India has officially recorded more than 414,000 coronavirus deaths, but scientists and researchers have said that number undercounts the real toll.
    They estimate the actual number of deaths is between 3.4 and 4.7 million.
  • July 11, 2021 - US Infection rates are over 50% higher than June lows although still only 10% of what they were in January.
    In part it is blamed on the July 4th weekend, but also on vaccine resistance in parts of the country. Nationally, 55.6% of all Americans have received at least one COVID-19 shot. The five states with the biggest two-week jump in cases per capita all had lower vaccination rates: Missouri, 45.9%; Arkansas, 43%; Nevada, 50.9%; Louisiana, 39.2%; and Utah, 49.5%.

    Joshua SA. Weitz at Georgie Tech developed a tool to assess the risk that one (or more) individuals in a group was infected which was documented in nature research in October, 2020.
    . S>
    You specify the group size and an ascertainment bias of 5 or 10. i.e. actual infections are 5 to 10 times higher than what is reported and get a risk probability.
    See COVID-19 Event Risk Assessment Planning Tool

    Objective:
    I was tired of the media only reporting total cases, it's meaningless for me. 1,000 new cases in Nevada is significant, 1,000 in California is not.
    I want to know the probability of meeting someone in the grocery store with coronavirus. To get that I need the Attack Rate, how many people are infected per 100,000 population.
    I have gone thru several iterations concentrating on death rates in the beginning because case rates were unreliable from the lack of testing.
    In "Substantial underestimation of SARS-CoV-2 infection in the United States" | Nature Communications Sept 2020, They estimate the actual number of infections from February to April, 2020 was 3 to 20 times higher than the number of confirmed cases.

    But it turns out only 18% - 80% of actual deaths are counted.
    See U. Washington study.

    I eventually found web sites that were reporting most of data I was interested in, shown here, you can click on charts to get current versions.

    We are concentrating on trends now from the world down to some towns in California. Where are the outbreaks, relative size of the them, history of safety plans etc..
    Also listing death rates, hospitilazions and positivity rate where possible.
    See more at rational.

    Rational:
    I started counting cases, but at the advice of my, Son, a medical journal editor, I changed this to report deaths which is likely more accurate than cases.
    Case numbers are under reported because of a lack of testing, pre-symptomatic, and non-symptomatic people, which vary by location.
    There are issues with death counts too, but fewer than with case counts.
    See Deaths vs Cases.
    After the Surge in the Southwestern US at the end of June, I started counting cases again, because of better testing and the 2 week lag between cases and deaths. Also the death rate is going down,

      There are other measurements that would be helpful in understanding the progress of the epidemic in different places, such as the number of new hospitalizations, the number of tests administered or the number of people showing any symptoms of respiratory illness. But confirmed coronavirus cases and deaths, however incomplete, are the most useful daily statistics currently available at a local level everywhere in the country.
    Hospitalizations and deaths lag cases by one to two weeks.
