Efficacy of face masks, neck gaiters and face shields for reducing the expulsion of simulated cough-generated aerosols medRxiv. From the Abstract: ” We used a cough aerosol simulator with a headform to propel small aerosol particles (0 to 7 μm) into different face coverings. An N95 respirator blocked 99% of the cough aerosol, a procedure mask blocked 59%, a 3-ply cloth face mask blocked 51%, and a polyester neck gaiter blocked 47% as a single layer and 60% when folded into a double layer. In contrast, the face shield blocked 2% of the cough aerosol. Our results suggest that face masks and neck gaiters are preferable to face shields as source control devices for cough aerosols.”
Synthesis and systematic review of reported neonatal SARS-CoV-2 infections Nature. A metastudy, n=176. From the Discussion: ” Our findings confirm that SARS-CoV-2 can infect neonates and that the majority of these infections occur postnatally, although vertical transmission may be possible in ~30% of cases…. [T]ransplacental transmission of SARS-CoV-2 is indeed possible and this is corroborated by a consistent background of laboratory findings…. The choice between rooming-in or mother-infant separation is an important one and the synthesis of available cases shows that the avoidance of separation might be associated with a higher risk of late-onset neonatal SARS-CoV-2 infections.”
Trump administration crackdown ‘couldn’t come at a worse time’ for hospitals HealthCare IT News. “Earlier this month, the Centers for Medicare and Medicaid Services announced that hospitals that were not in compliance with [Covid] reporting requirements from the U.S. Department of Health and Human Services could find their participation in the federal programs put at risk.” You can bet the hospitals aren’t having any problem at all coding for billing. It’s only when they have to start coding for health care that they start whinging.
Inside the Fall of the CDC Pro Publica. Very good; among other things, the first real explanation, nine months after the fact, of the CDC Covid testing debacle* (originally blamed on contractors, IIRC). My preference for coverage priorities would be: 1) Neoliberal hollowing out; 2) the testing debacle; and 3) political interference, because the first two corrode the clout of the CDC and lead to the third, and this article reverses that order, but it’s nevertheless very good. NOTE * Casting doubt on the ability of the PMC to regulate itself, exactly like the ObamaCare MarketPlace launch debacle. PMC professional associations also have this issue.
A National Security Reckoning Hillary Clinton, Foreign Affairs. “The COVID-19 crisis should be a big enough jolt to rouse the country from its sleep.” Yes, it was hard to sleep in the car, but I managed it.
