Researchers used both plastic and skin from cadavers to see how long the BA.2 subvariant lasts on surfaces, while another study gives insight on how it can be treated.
"They looked at how long the virus remains on a surface and can still be recoverable. They used both plastic and skin from cadavers," said Dr. George Rutherford, UCSF Professor Epidemiology.by researchers in Japan was held in a lab which could influence its outcome. Researchers tested multiple COVID variants and noticed that Omicron lasted the longest.
Dr. Rutherford and UC Berkeley Infectious Disease Expert Dr. John Swartzberg agree that the greatest risk of infection continues to be by droplets in the air. "At least with the cadaver skin experiments, they were all neutralized within 15 second without ethanol alcohol," said Dr. Rutherford. "Either close to somebody where larger droplets can get onto our mouth or nose, or eyes or even distances. Particularly inside 30 feet away if the virus gets inside and floats and we inhale it," said Dr. Swartzberg.
