Understanding the evolution of SARS and COVID-19 type viruses

As COVID-19 sweeps the world, related viruses quietly circulate among wild animals. A new study shows how SARS-CoV-2, the virus that causes COVID-19, and SARS-CoV-1, which caused the 2003 SARS outbreak, are related to each other. The work helps scientists better understand the evolution of these viruses, how they acquired the ability to infect humans […]

Openly available toolkit to help lab-based coronavirus research

During the SARS-CoV-2 outbreak, laboratories worldwide have pivoted from their usual research to working to identify new COVID-19 drug and vaccine candidates. This experimental work requires access to clinical isolates and systems that allow genetic manipulation of SARS-CoV-2. A new paper reports an openly available SARS-CoV-2 laboratory research toolkit aimed at increasing availability of these […]

Study estimates two-thirds of COVID-19 hospitalizations due to four conditions

A new study estimates 64 percent of adult COVID-19 hospitalizations in the U.S. may have been prevented if there were less obesity, hypertension, diabetes, and heart failure. The model suggests notable differences by age and race/ethnicity in COVID-19 hospitalizations related to these conditions.

Study finds short window for donating convalescent plasma to COVID-19 patients

The optimal timeframe for donating convalescent plasma for use in COVID-19 immunotherapy, which was given emergency use authorization by the Food and Drug Administration in August 2020, is within 60 days of the onset of symptoms, according to a new study. The research also reveals that the ideal convalescent plasma donor is a recovered COVID-19 […]

Novel pooled testing strategies can significantly better identify COVID-19 infections

A novel approach to pooled testing could help identify up to 20 times more COVID-19 infections per day than individual testing. Simple pooled designs could be implemented with minimal changes to current testing infrastructures in clinical and public health laboratories.
