Coronavirus & skin: New study reinforces importance of handwashing
Japanese researchers deterimine SARS-CoV-2 virus can survive on human skin for nine hours.
we know the SARS cov to virus can be spread through droplets and aerosols, but you can also become infected by touching contaminated surfaces, then touching parts of your face. That begs the question. How long can the virus actually survive on our hands and faces? Figuring out how long a contagious virus could survive on human skin isn't an easy challenge. Not many people are willing to have live SARS cov to smeared on them just for science. That's why Japanese researchers used an unusual alternative. Human skin collected it autopsy about 24 hours after death. Their study, published in the journal Clinical Infectious Diseases, tested the survival time of the SARS cov to virus on human skin samples as well as other surfaces, including stainless steel and glass. And they compared it to the survival time of influenza virus. What they found was significant. The SARS cov to virus could survive on human skin for nine hours, significantly longer than the roughly two hours that the flu virus could remain a threat. Even more significantly, the SARS cov to virus remained active for 11 hours when it was mixed with mucus as it would be from a cough or sneeze The good news. When the samples were exposed to an 80% alcohol type hand sanitizer, the virus was inactivated within 15 seconds.
