Summary of Evidence Related to Indoor Ventilation to Reduce SARS-CoV-2 Transmission

This updated in-depth summary (previously released on December 21, 2020) is issued in response to new information that we received about updated definitions of aerosol particles that show that larger respiratory particles (<100 μm) can remain airborne for extended periods, and that in enclosed areas with poor ventilation, these aerosols containing infectious SARS-CoV-2 can spread beyond 6 feet and build up in a room. We apologize for not including this information in the earlier version of this summary.

How Widespread is Mask-Wearing in Washington? UW Study Aims to Find Out, Starting in King County (includes Judith Wasserheit and Brandon Guthrie)

Just as important, that plan — like the vaccine itself — has to be trusted and accepted by the general public.

Evidence Related to Schools During the COVID-19 Pandemic

Most countries world-wide implemented localized or national school closures in response to the COVID-19 pandemic, with estimates of >65% of enrolled children globally affected by school closures.1 Since the early pandemic, schools in many settings around the world have fully or partially re-opened for in-person instruction, while in other settings schools have re-opened exclusively using online learning.

UW Medicine, Fred Hutch scientists will jointly test whether the monoclonal drug can prevent infection among people exposed to COVID-19.

Researchers at UW Medicine and the Fred Hutchinson Cancer Research Center are jointly testing monoclonal antibodies created by Regeneron Pharmaceuticals to prevent COVID-19, and are starting to recruit patients.

How COVID-19 Affects Some People Long After They Become Infected with the Coronavirus (includes Jennifer Ross)

Nearly eight months after the pandemic was declared, researchers are gaining a more complete understanding of how the new coronavirus affects people.

One thing they’re noticing as time goes on: some people diagnosed with COVID-19 feel sick long after contracting the virus.
