The coronavirus remains active on human skin for nine hours, Japanese researchers have found. One discovery found that frequent hand washing is required to fight the COVID-19 pandemic.
The pathogen that causes the flu survives on human skin for around 1.8 hours, by comparison, according to the study published this month in the journal Clinical Infectious Diseases.
“The nine-hour survival of SARS-CoV-2 (the strain of virus that causes COVID-19) on human skin can increase the risk of contact transmission compared to IAV (Influenza A Virus) and thus accelerate the pandemic,” it said .
The research team tested the skin taken from autopsy samples about a day after death.
Both the coronavirus and the flu virus are inactivated within 1
“The longer survival of SARS-CoV-2 on the skin increases the risk of contact transmission. However, hand hygiene can reduce this risk, ”the study says.
The study supports the World Health Organization’s guidelines on regular and thorough hand washing to limit transmission of the virus, which has infected nearly 40 million people worldwide since it first appeared in China late last year.
