Covid Loses Most Infection Capacity After 20 Minutes In Air: Study

Researchers found that the virus loses 90% of its contagion capacity 20 minutes after becoming airborne and that most of that loss happens in the first five minutes of it reaching the air, according to the study, that simulates how the virus behaves after exhaling.
Coronavirus loses most of its ability to infect shortly after being exhaled and is less likely to be contagious at longer distances, a study from the University of Bristol's Aerosol Research Centre showed.

With some countries opening the debate in Europe about an endemic phase to the virus, insights into the way the virus travels across the air will help guide containment measures. The results of this study, which hasn't been peer-reviewed, reinforce the notion that the virus is mainly transmitted over short distances, providing fresh support for social distancing and mask-wearing as means to curb infections.
Investigators in the U.K. focused on three of the earlier coronavirus variants, not including the most recent omicron, but said they don't expect other circulating variants to behave differently.
