A study by Wake Forest Baptist Health has found that between 12-14% of people tested in North Carolina have antibodies for the coronavirus — meaning they have been exposed to the virus — with most of them showing little or no symptoms.
The majority of the study participants are in the Triad area.
The findings suggest that COVID-19 is less deadly than originally thought and that the death rate for the disease could be in the range of 0.1%.
But the study also shows that there is significant community spread and that efforts so far to curtail COVID-19 are faltering.
“It’s a double-edged sword,” said John Sanders, the chief of infectious diseases at Wake Forest Baptist. “We are clearly seeing a rapid increase in the number of people that we have antibody evidence who have been infected.”
But he said “the vast majority of these people have very few or no symptoms.”
“We can look at it and say the death rate is lower than we have estimated,” Sanders said. “The severity of symptoms is lower than we estimated and the vast majority of people who were infected are going to do fine.”
There are about 10.5 million people in North Carolina. If 14% of the population has been infected with the coronavirus, that would translate into about 1.47 million people.
The state has more than 66,000 confirmed cases as of Wednesday and 1,373 confirmed COVID-19 deaths.
Stanford U. Professor John Ioannides, a medical doctor and statistician best known for his research Into the reliability and reproducibility of the medical literature, points out that mortality for those below 45 is “almost zero”, and slams statewide lockdowns. (I approve of lockdowns as a targeted measure in densely populated areas, but don’t believe in their use as blunt instruments.)
“The death rate in a given country depends a lot on the age structure, who are the people infected, and how they are managed,” Ioannidis said. “For people younger than 45, the infection fatality rate is almost 0%. For 45 to 70, it is probably about 0.05%-0.3%. For those above 70, it escalates substantially.”
Several states have seen spikes in cases, especially in the southeastern part of the country, where lockdown measures were lifted earlier than in other states.
The mortality rate nationwide appears to be tapering, however, a trend U.S. health officials attribute to a younger age bracket in terms of infection. The national single-day death rate from the virus fell to a three-month low last month. Additionally, Massachusetts reported zero new deaths from the coronavirus on Tuesday for the first time since March.

Advantages of the Parent Nucleoside GS-441524 over Remdesivir for Covid-19 Treatment
Victoria C. Yan* and Florian L. Muller
While remdesivir has garnered much hope for its moderate anti-Covid-19 effects, its parent nucleoside, GS-441524, has been overlooked. Pharmacokinetic analysis of remdesivir evidences premature serum hydrolysis to GS-441524; GS-441524 is the predominant metabolite reaching the lungs. With its synthetic simplicity and in vivo efficacy in the veterinary setting, we contend that GS-441524 is superior to remdesivir for Covid-19 treatment.
(3) Was the lockdown worth it? The Daily Telegraph has a long piece in which twelve experts and writers of the paper make their cases pro and con.
(4) Israel, with escalating COVID-19 infections in what is probably the one pronounced second wave at the moment, announced tightened restrictions. Prof. Eli Waxman, head of the Coronavirus ad hoc committee, speaks out in this interview. This needs to be seen in the context of a tug-of-war between public health authorities fiercely defending their own turf, and perceived “upstarts” with “no background in medicine” (never mind what they can bring to the table in terms of logistics, tracing, and testing knowhow). A somewhat similar situation pertained in the US at least at the beginning of the outbreak, where it often seemed the CDC was excessively preoccupied with protecting its own backyard — particularly on testing, whic Germany wisely decentralized from the beginning.
