Research shows Coronavirus Remains on Human Skin for 9 hours


According to Japanese researchers, the coronavirus remains active on human skin for nine hours. This proves that there is a need for frequent hand washing to combat the Covid-19 pandemic.

The study published this month in the Clinical Infectious Diseases journal proved that the pathogen that causes the flu survives on human skin for about 1.8 hours by comparison said the reports.

According to the study, the nine-hour survival of SARS-CoV-2 (the virus strain that causes Covid-19) on human skin may increase the risk of contact transmission in comparison with IAV (influenza A virus), thus accelerating the pandemic.

The research team tested skin collected from autopsy specimens, about one day after death. 

Both the coronavirus and the flu virus are inactivated within 15 seconds by applying ethanol mostly used in hand sanitizers.

The longer survival of SARS-CoV-2 on the skin increases contact-transmission risk; however, hand hygiene can reduce this risk, the study said.

The study backs World Health Organization guidance for regular and thorough hand washing to limit the spread of the virus, which has infected nearly forty million people around the world since it first appeared in China late last year.
