The coronavirus stays on the skin five times longer than the flu

The coronavirus remains active on the skin for nine hours, Japanese researchers found, compared to about 1.8 hours for the pathogen that causes influenza.

The study published in the journal Clinical Infectious Diseases therefore shows once again the need to wash your hands very regularly. as a barrier gesture for limit virus transmission. 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, says the study.

Coronavirus and influenza virus inactivated 15 seconds after using disinfectant

Japanese researchers also tested skin samples taken from autopsy specimens about a day after death. The coronavirus and the influenza virus are both inactivated within 15 seconds by the application of ethanol, used in hand sanitizers.

Longer survival of SARS-CoV-2 on the skin increases the risk of contact transmission, but hand hygiene may reduce this risk, underlines this study.

At least 1,105,691 deaths and nearly 39.4 million infections have been recorded since the start of the pandemic in China at the end of last year, according to a count carried out by AFP on Saturday.
