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.

* Deaths are significantly undercounted. See Data Accuracy
Mexico and Russia were significantly undercounted in a May 2021 U. Washington Study below.
If you account for that, Russia would have 8,400 deaths per million, Mexico would have 4,700 deaths per million and India would have 3,600 deaths per million per a July 2021 Wall Street Journal report.
China could be up to 130
Deaths in other countries could be up to 40% higher.

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

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.

† 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.

"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.

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.

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.

By the end of November the average rate for the whole country was 5 times higher than it was in April.

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.
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.

See Variants for the sublenage 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.
Feb 28, 2023 California ends the COVID-19 State of Emergency.

Californias COVID-19 State of Emergency ends today. What does it mean for you? | UC Davis Health
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."


 How to protect yourself from COVID subvariant BA.5 | UC Davis.

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 hasnt 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.


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. 

Nov 1, 2021 - Coronavirus death toll hits 5 million worldwide
Sept 8, 2021, 2021 - 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.

July 20, 2021 - Indias 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.

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.
 June 3 - The W.H.O. warned of a surge of new infections in Africa, which could set off a third wave for the continent as winter arrives.
June 1 A new surge in Latin America has been attributed to the spread of the Brazil variant.
May 31 - 42% of the US population  are fully vaccinated.

52% of the California population  are fully vacinated. 

8% of Canadians are fully vaccinated. 

Fully vaccinated in Europe: UK 37%; Spain 19%; Italy 19%; Germany 17%; France 16%; Russia 8%

According to the Pan American Health Organization (PAHO) Only 3% of the regional population in Latin America are fully vacinated. as of May 19.

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.
