Coronavirus remains active on skin for 9 hours, study finds

According to a study by Japanese researchers, the coronavirus stays active on the skin five times longer than the flu virus. This discovery therefore confirms the need to wash your hands frequently to fight against the Covid-19 pandemic.

Indeed, the covid-19 stays active for nine hours on the skin whereas in comparison, the pathogen that causes influenza, only survives on the skin that for about 1.8 hours. “The nine hour survival of SARS-CoV-2 (the strain of the virus that causes Covid-19 disease) on human skin may increase the risk of transmission by contact compared to the IAV (Influenza A Virus or influenza A), thus accelerating the pandemic (…).

The longer survival of SARS-CoV-2 on the skin hasincreases the risk of contact transmission, but hand hygiene can reduce this risk“, says the study published this month in the journal Clinical Infectious Diseases. In addition, the coronavirus, like the flu virus, are both inactivated within 15 seconds by the application of ethanol found in hand sanitizers.

In order to carry out their study, Japanese researchers tested skin samples taken from autopsy specimens approximately one day after death. As illustrated in their research, the researchers support the recommendations of the World Health Organization (WHO) for regular and thorough hand washing. Washing necessary to limit the transmission of virus.
