A top scientist questioned virus lockdowns on Fox News. The backlash was fierce.
- Based on their results, they estimated that the county probably had more than 50 times the 1,000 cases that had been officially reported. The finding, if correct, meant some influential estimates of the virus’s lethality had been exaggerated. The Stanford paper estimated a mortality rate among the infected of 0.2 percent or less — well below the 0.9 percent figure used in a widely reported Imperial College London study that helped shape lockdown policies –

- Administrators at the Stanford School of Medicine launched a fact-finding review, which uncovered “no evidence that any of the study funders influenced the design, execution, or reporting of the study,” according to documents reviewed by The Washington Post. But the review did conclude that funders’ involvement could “suggest an apparent conflict of interest in the public mind,” and it faulted the authors for shortcomings in other areas, such as the Facebook ads they used to recruit test subjects and insufficient oversight of the volunteers who collected blood samples.

Ioannidis and his co-authors corrected and revised some calculations in the paper after it was made public, a not uncommon practice for studies posted online before peer review. But they stood by their results, which would prove to be within the range of figures observed in other states and countries. (The infection fatality rate differs from the case fatality rate, which measures mortality only among confirmed cases. Because cases have been undercounted at every stage of the pandemic, the infection fatality rate is usually the lower of the two numbers.) “That’s exactly the way that science should work,” Ioannidis declared. –

COVID-19 antibody seroprevalence in Santa Clara County, California
Background. Measuring the seroprevalence of antibodies to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is central to understanding infection risk and fatality rates. We studied Coronavirus Disease 2019 (COVID-19)-antibody seroprevalence in a community sample drawn from Santa Clara County. –

• Seroprevalence studies of Coronavirus Disease 2019 (COVID-19) provide estimates of the extent of infection that are more representative of true transmission than indicated by case numbers.
  
• In late March 2020, the seroprevalence of antibodies to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in Santa Clara County, California was estimated at 2.8% [95% confidence interval (CI) 1.3–4.2%] after weighting for county demographics and adjusting for test performance (1.5% unadjusted, 95% CI 1.1–2.0%).
  
• These prevalence point estimates imply that 53 000 (95% CI 26 000 to 82 000 using weighted prevalence) people were infected in Santa Clara County by late March—many more than the ∼1200 confirmed cases at the time.
  
• Using the estimated number of infections and the deaths in Santa Clara County at the time, we estimate a local infection fatality rate of 0.17%.

- A record-high 2,544 children were hospitalized with Covid-19 on September 10, according to data from the US Department of Health and Human Services.
-- An average of 341 pediatric Covid-19 patients were admitted to hospitals every day during the week ending September 12, according to data from the US Centers for Disease Control and Prevention.
-- More than 57,000 children have been hospitalized with Covid-19 since August 2020, according to CDC data. Many of those children had no known preexisting conditions.
-- While childhood Covid-19 deaths are still rare, that number is increasing. At least 529 children have died from Covid-19, according to CDC data.

Doctors say it's critical to protect children against the Delta variant -- not just for the sake of their health, but to preserve in-person learning and help prevent more aggressive variants from setting the entire country back.

Is preserving in-person learning as opposed to video-schooling a bad goal ?

And I read the other articles

impact on school and parents (including psychological impacts)

We can preserve in-person learning at a stroke by not quarantining entire classes unnecesarily when one child "fails" a rapid test while asymptomatic. No capital outlay required! At this point school is being disrupted by public health policy far more than it is being disrupted by sickness as such.
