• Nov 11 - BQ.1 and BQ.1.1 have increases from a combined 27% of new cases on Oct 29 to 44% of cases in the U.S. BA.5 has dropped from 59% to 30%
  See US Variants below New cases in Japan have increased 66% and South Korea have increases 37% over the same 2 week period.
• 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
• 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.

  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 Children’s 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 haven’t 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.
  Mask mandate for plains extended until May 3.
• 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 hasn’t caused a fresh surge in cases."" Globally, Covid cases have plunged 21% over the past week.
• Dec 20, 2021 - The Omicron variant accounts for 3/4 of all new cases in the US and is in 40 states.

• 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.

• Nov 1, 2021 - Coronavirus death toll hits 5 million worldwide
• Sept 8 - New cases among children and teenagers have reached the highest weekly level since the pandemic's start, at more than 250,000 for the week ending Sept. 2 — more than a fourth of all new cases that week in the U.S.
• July 27 - CDC Advises Masking Indoors even for vaccinated people In Counties With Substantial Or High Coronavirus Spread.
  2/3 of counties in the country have substantial or high rates.
  See New mask guidance
• July 20, 2021 - India’s Covid-19 Death Toll Is Likely in the Millions | WSJ
  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%.
• July 7, 2021 - Coronavirus death toll hits 4 million worldwide as the Delta variant spreads.
  

  North America and Europe are still well off their highs of 450 and 350 cases per million per day.
  Africa's cases cases are concentrated in 6 countries, Tunisia, Nambia, South Africa, Botswana, Libia and Zambia, where the combined case rate is 350 per day per million.

• June 14 - The CDC declared the Delta variant a "variant of concern," a designation given when there is increased evidence of factors such as transmissibility or severity or reduced effectiveness of vaccines or treatments. See the Delta variant in facts.

- North America includes Central America, the Caribbean and Greenland.
* The Omicron peak was on or before Jan 31 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 US death rate was about twice that of other regions because fewer people got vaccinated. By August of 2021 about 55% of Americans had at least 1 dose while 70% of Canadians and people in the UK were vaccinated. That resulted in around 1,500 unnecessary US deaths per day. In May 2022 the cumulative US death toll hit 1 million.

Number's are 7-day averages.
1,000 deaths per million is 0.1% of the population.
See Our World in Data for current rates.
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.
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.

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.

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. My theory is that the western countries have gotten close the herd immunity (A CDC report ) which kept their new infection rates down.
In October Europe seemed to be starting another surge. The US had traditionally lagged them by a couple of weeks, so we'll have to see what happens.

† 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.

I don't know why the New York Times numbers are always higher than the CA Department of Public Health numbers (see Yolo and San Mateo below).

City Wastewater Data

Healthy Davis Together Historic Wastewater Testing

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.

Peru    6,002  Bulgaria 4,331  Hungary 3,868  
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 don’t 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
14.9 million excess deaths associated with the COVID-19 pandemic in 2020 and 2021
They measured the increase in the death toll, which was COVID-19 directly (due to the disease) or indirectly (due to the pandemic’s impact on health systems and society). e.g. lack of access to ERs and intensive care.

Most of the excess deaths (84%) are concentrated in South-East Asia, Europe, and the Americas.

It 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.
Excess mortality includes deaths associated with COVID-19 directly (due to the disease) or indirectly (due to the pandemic’s 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 2021–February 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. See

"Estimating excess mortality due to the COVID-19 Pandemic a study by Researchers at the University of Washington’s 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 100 000 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 (792 000), 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."

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.

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 government’s 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.

1,000 deaths per million is 0.1% of the population.

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.

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.

Cumulative Deaths:

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.
As of May 2022 it has the highest new case rate rate. It is still lower than historical rates.

See Current Region data above.

I Had a theory that the regions which had higher rates in the past have developed a herd immunity.
However, as of the end of July Southern California and the San Joaquin Valley were back on top with the highest rates, so that theory doesn't hold.
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.

On January 10, 2022 Davis had an average of 210 new cases per day per 100,000, higher than Yolo Co, California and the US.
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 35,000 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. If 150 of the 210 cases (15 day average on 1/7) were students that would 0.4% of students.

Why are the cases per 100K different in the NY Times report and the California State report? (Yolo and San Mateo below)
I don't know why the Times shows higher numbers per 100K than the state data below (only San Mateo and Yolo are shown but numbers are higher for all counties).
I sent the Times a question, but haven't heard back.

Both numbers are probably low because of many cases not being reported.

City Wastewater Data

Healthy Davis Together Historic Wastewater Testing

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.

Risk-Assessment
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.

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.
