However, presymptomatic individuals, those who are infected but haven’t yet begun to show symptoms, accounted for 75 percent of confirmed transmission events, researchers report in an April dispatch of Emerging Infectious Disease.

The seven asymptomatic cases did not transmit the virus to any of their contacts. Twenty-two of the 29 transmission events occurred when an infected person who was not yet showing symptoms interacted with people outside of their household.

Why indoor spaces are still prime COVID hotspots Risks shoot up when virus particles accumulate in buildings, but it’s not clear how best to improve ventilation. Dyani Lewis nature
 

When Lidia Morawska leaves home, she takes with her a slick, shoe-sized device that provides some sobering insights about the restaurants and offices she visits. Outside these buildings, her carbon dioxide monitor reads just above 400 parts per million (p.p.m.). But indoors is a different story.

A 4th COVID-19 wave may look different than previous surges

Mon, 2021-03-29 09:08 — mike kraft
Why a 4th COVID-19 wave may look different than previous surges As coronavirus cases and hospitalizations creep up across the country, health officials are continuing to urge caution, warning that despite the acceleration in the pace of vaccinations, the nation could face a potential fourth wave of COVID-19 infections, if Americans let their guards down too rapidly. “We’re seeing rising cases in several locations around the world, including in some U.S. states so a fourth wave seems possible,” Rachel Baker, an epidemiologist at Princeton University, told ABC News.
