The research team examined the skin obtained from autopsies, approximately one day after death.

The coronavirus remains active on human skin for nine hours, five times longer than the flu virus, according to a study by a group of Japanese researchers published in a scientific journal, reinforcing, they noted, the need to wash hands with frequency to combat the Covid-19 pandemic.

In comparison, the pathogen that causes the flu survives on human skin for about 1.8 hours, according to the study published this month in the journal Clinical Infectious Diseases, reported by the AFP news agency.

“The nine-hour survival of SARS-CoV-2 (the virus that causes Covid-19) in human skin may increase the risk of contact transmission compared to IAV (influenza A virus), thus accelerating the pandemic “, indicates the study.

“Longer survival of SARS-CoV-2 in the skin increases the risk of transmission by contact; however, hand hygiene can reduce this risk.”

The research team examined the skin obtained from autopsies, approximately one day after death.

Both the coronavirus and the flu virus are inactivated in 15 seconds by applying ethanol, which is used in hand sanitizers.

“Longer survival of SARS-CoV-2 in the skin increases the risk of transmission by contact; however, hand hygiene may reduce this risk,” the study noted.

The study supports the World Health Organization (WHO) recommendations to regularly wash your hands thoroughly to limit transmission of the virus, which has infected nearly 40 million people worldwide since it first appeared in China. late last year.
