As President Trump pushes the possibility of a vaccine this year, the C.D.C. has outlined technical scenarios to state public health officials for an unidentified Vaccine A and Vaccine B.
The UNC School of Medicine laboratory of Camille Ehre, PhD, Assistant Professor of Pediatrics, produced striking images in respiratory tract cultures of the infectious form of the SARS-CoV-2 virus produced by infected respiratory epithelial cells. The New England Journal of Medicine featured this work in its “Images in Medicine” section, published today.
Op/Ed: Op-Ed: That CDC 6% COVID Death Rate, Explained
Only a few weeks into fall semester, colleges and universities across the country are urgently trying to control clusters of COVID-19 infections on their campuses. Thousands of cases have been reported nationwide, forcing universities to switch to virtual classes and either quarantine or, in some cases, send students back home whether or not they’re sick.
This weekend is the unofficial end of summer, the season when, President Trump had promised, the weather would make covid-19 disappear, like a miracle. Millions of Americans shared that hope and it’s easy to understand why: although many of history’s most dreaded epidemic diseases — cholera, polio, diphtheria — are at their worst in summer, the closest precedents for covid-19 seemed to be the influenza pandemic of 1918, the SARS pandemic of 2002 or the annual seasonal flu, all of which, as with so many respiratory infections, tend to fade away as summer arrives.
The wide swath of groups receiving the highest priority for any potential COVID-19 vaccine should expand to include particular races and ethnicities, as well as certain occupations, advocates told the National Academies of Sciences, Engineering and Medicine (NASEM) on Wednesday.
The scale of the COVID-19 pandemic in the Americas is unprecedented, an official with the Pan American Health Organization (PAHO) said today in a press conference. And nowhere has its impact been bigger than in the healthcare workforce.
Nurses are increasingly being forced to reuse N-95 masks, sometimes for five days or longer, and growing numbers of nurses said they feel unsafe reusing masks even after they were decontaminated, according to the latest in a series of nursing surveys.
The White House Coronavirus Task Force coordinator, Dr. Deborah Birx, on Wednesday dismissed the notion that the Trump administration was considering a strategy of allowing Americans to become infected with coronavirus in order to reach “herd immunity.”
Video at the link – We all know that if someone with the coronavirus coughs or sneezes on you, you’re at risk of catching it. But even when we speak or laugh or breathe, particles come out of our noses and mouths. Big bits of spittle can fly out when you’re shouting and singing, along with respiratory droplets and tiny aerosolized particles that come out in clouds that may linger in the air. And if we’re infected with the coronavirus — even if we don’t have any symptoms — those excretions could contain live, contagious SARS-COV-2 that can make others sick.
JAMA today published the results of three randomized controlled trials spanning 12 countries, a prospective meta-analysis, and a commentary, all but one—which had inconclusive results—supporting the use of systemic corticosteroids in critically ill COVID-19 patients, regardless of age, sex, duration of symptoms before treatment, or the need for mechanical ventilation.
Since the start of the pandemic, scientists have learned that SARS-CoV-2, the virus that causes COVID-19, is quite cunning. When the virus enters the body, it’s capable of turning off an entire branch of the immune system, allowing it to spread for days before the immune system can sound the alarm on the intruder. However, researchers still don’t know the full scope of tissues and cell types that are most vulnerable to SARS-CoV-2. Most research has focused on identifying genes and pathways that facilitate the virus’s entry into lung cells – yet both clinical and scientific data indicate that it can cause damage in a wide range of organs.

Public health departments, which have struggled for months to test and trace everyone exposed to the novel coronavirus, are now being told to prepare to distribute COVID-19 vaccines as early as Nov. 1.
Drugmakers made big promises for a quick turnaround on coronavirus vaccines. The moment of truth for the front-runners is coming as soon as this month. The first results showing whether a vaccine can stop people from getting the virus could come by mid-September from AstraZeneca Plc, according to Airfinity Ltd., an analytics company that tracks drug trials. The drugmaker has pledged as many as 30 million doses to the U.K. by the end of the month.

Coping in Quarantine
A poem, from 1918
Oh, we are quarantined, I guess
For ‘bout a million years
But if we don’t get out of here
We’ll burst right out in tears
