COVID-19 day 227: 📈 Why herd immunity is not a strategy: 03 September 2020
US daily per capita data resemble South America more than Europe; another celebrity infection, The Rock; first death post-Sturgis rally; more on myocardial infections and athletes
Today was day 227 since the first case of coronavirus disease was announced in the United States. Today, I am comparing Wednesday data with Monday’s report.
There are now 26 million cases worldwide; last week, there were 24 million.
In the US, the annual Sturgis, SD, Harley-Davidson-influenced motorcycle rally has claimed its first victim, a Minnesota man in his 60s. There have been at least 260 cases in 11 states linked to the event.
Now, just over two weeks after the conclusion of the rally, the Midwest and the Dakotas in particular are seeing a spike in coronavirus cases even as infections decline or plateau in the rest of the country. South Dakota’s seven-day averages for new cases stood at 347 on Sept. 2 compared to 107 two weeks earlier and its total caseload was 14,003, up from 10,566, according to The Post’s tracking. In North Dakota, the seven-day averages for new cases was 257, up from 142 two weeks earlier and its total caseload was 12,267, compared to 8,968.

⓵ One big thing - US numbers remain problematic
Saying that the daily US COVID-19 case rate per million is less than South American countries does not feel like a bragging right. Ditto Mexico and South America for the daily death rate. The exception in daily new cases is Spain, which is having a spike (chart below) that has just surpassed its initial outbreak.
A reminder the the US spends more on health care per capita than any other developed nation. And yet look at us.
As you can see from the next chart, US daily case numbers per capita have not yet declined to March peak (less than 100 per day), when all things COVID-19 were new.
As we approach Labor Day weekend, Dr. Anthony Fauci noted that cases are increasing in seven states: Arkansas, Illinois, Indiana, Iowa, Missouri, North Dakota, and South Dakota. “Those states are starting to see an increase in the percent positive of their testing; that is generally predictive that there’s going to be a problem.”
This Axios map suggests there are a lot more states that need to worry.

But “herd-immunity strategy” is a contradiction in terms, in that herd immunity is the absence of a strategy. Herd immunity is an important public-health concept, developed and used to guide vaccination policy. It involves a calculation of the percentage of people in a population who would need to achieve immunity in order to prevent an outbreak. The same concept offers little such guidance during an ongoing pandemic without a vaccine. If it were a military strategy, it would mean letting the enemy tear through you until they stop because there’s no one left to attack…
[Sweden] still [has] a ban on public gatherings of 50 people. Gatherings for religious practice? Banned. Theatrical and cinema performances? Banned. Concerts? Banned. And this is what bothers me. Our president did a rally in Tulsa. That would have been banned in Sweden.

In this Perspective, David M. Morens and Anthony Fauci explore what they describe as “a pandemic era,” marked by SARS, MERS and COVID-19. They focus on human triggers such as deforestation, urban crowding, and wet markets for wild game.
There are many examples where disease emergences reflect our increasing inability to live in harmony with nature. Nipah virus emergence followed agricultural burning of forests, which led to displacement of infected bats; bats then went to roost in trees that shaded intensively farmed pigs that were crowded into small areas, which led to infection of pigs via bat droppings, which in turn led to human outbreaks in pig farmers.

[A] research team is trying to determine whether the several million people who merely carry one copy of the sickle cell mutation — but do not have the disease itself — could be more vulnerable to Covid-19, and whether that might be one reason the virus is disproportionately sickening and killing Black Americans.
You may have read or heard that Wayne Sebastianelli, Penn State director of athletic medicine, said that that 30-35% of Big Ten athletes who had tested positive for the coronavirus appeared to have myocarditis when subjected to an MRI scan. That comment has been walked back.

The virus was not created in a lab and the weight of evidence is that it was not released intentionally. Although early reports tied the outbreak to a market in Wuhan, China, analyses of genomic data have suggested that the virusdeveloped elsewhere.
