These countries crushed covid-19 — but are now reporting higher infection rates than the U.S. – Washington Post

Israel, Spain and France all fought the novel coronavirus into abatement in the first months of the pandemic with tough measures that won international praise. But the three countries now share a painful distinction: Their infection rates have shot past the United States, even though Americans never got the virus under control.

‘You Need a Test’: CDC Reverses Guidance for Asymptomatic COVID Contacts – Med Page Today

Asymptomatic people who have been exposed to COVID-19 should be tested, the CDC said on Friday, in a reversal of controversial guidance the agency introduced in late August.

How do you ship millions of vaccine doses at minus 112 degrees Fahrenheit? There are many logistical challenges. – New York Times

A number of the leading Covid-19 vaccines under development will need to be kept at temperatures as low as minus 80 degrees Celsius (minus 112 degrees Fahrenheit) from the moment they are bottled to the time they are ready to be injected into patients’ arms.

How could wearing a mask help build immunity to COVID-19? It’s all about the viral dose – The Conversation

While these face coverings may not completely prevent us from getting infected with COVID-19, they probably reduce the number of virus particles we inhale — the “viral dose”. Scientists think a lower viral dose can reduce the severity of the disease we get. Indeed, where universal face masking is implemented, a much higher proportion of new infections with COVID-19 are asymptomatic.

Clinical Considerations

Neurological manifestations of SARS-CoV-2 – a controversy “gone viral” – Oxford Brain Communications

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first appeared in December 2019 in Wuhan, China and developed into a worldwide pandemic within the following three months causing severe bilateral pneumonia (Coronavirus disease 2019; COVID-19) with in part fatal outcomes. After first experiences and tentative strategies to face this new disease, several cases were published describing SARS-CoV-2 infection related to the onset of neurological complaints and diseases such as, for instance, anosmia, stroke or meningoencephalitis. Of note, there is still a controversy about whether or not there is a causative relation between SARS-CoV-2 and these neurological conditions. Other concerns, however, seem to be relevant as well. This includes not only the reluctance of patients with acute neurological complaints to report to the emergency department for fear of contracting SARS-CoV-2 but also the ethical and practical implications for neurology patients in everyday clinical routine. This paper aims to provide an overview of the currently available evidence for the occurrence of SARS-CoV-2 in the central and peripheral nervous system and the neurological diseases potentially involving this virus.

I See People Wearing Disposable Coveralls On Planes. Good Idea? – NPR

OK, so I’d planned a flight to visit my grandkids last week because with cold weather and the flu season looming in the U.S., it seemed like late summer/early fall might be a good window of opportunity to travel. I was nervous. Airports! Airplanes! Droplets! Aerosolized particles! Of course I wore a mask — that’s required. A friend told me she’d flown wearing a pair of disposable painters’ coveralls — an ankle-length jumpsuit with full sleeves — over her clothes, then took them off and threw them away upon arrival. I’ve also seen photos of air travelers around the world wearing what appear to be disposable space suits.

Experimental Medicines For COVID-19 Could Help Someday, But Home Runs Not Guaranteed – NPR

Many drugs are in the works, and those that succeed could play a role in reducing symptoms and sometimes saving lives. But, given the way drugs are developed, it’s unlikely that any single medicine will be anywhere as potent against the coronavirus as a successful vaccine.
