Coronavirus Becomes 90% Less Infectious Within 20 Minutes of Being Airborne, Reveals UK Study

News 18  

A groundbreaking new study that attempts to find how the deadly coronavirus survives in exhaled air has revealed that the virus becomes 90 per cent less infectious within 20 minutes of becoming airborne therefore losing most of its ability to infect after the first five minutes. While conducting the study, the researchers developed an apparatus to generate virus-containing particles and allowed them to float between two electric rings for anywhere between five seconds and 20 minutes in a tightly controlled environment. If the air is less than 50 per cent humid, the virus loses half of its infectivity within five seconds and another 19 per cent loss over the next 5 minutes. I’m not saying that doesn’t happen, but I think still the greatest risk of exposure is when you’re close to someone,” the study’s lead author Prof Jonathan Reid told The Guardian.
