Tokyo, Japan-Japanese researchers found that the activity of the coronavirus on human skin remained for nine hours. They found a finding that indicated the need to wash hands frequently to fight the COVID-19 pandemic.
In contrast, the study published this month in the journal “Clinical Infectious Diseases” showed that the pathogen that causes influenza can survive on human skin for approximately 1.8 hours.
“9-hour survival time of SARS-CoV-2 [the virus strain that causes COVID-19] Compared with IAV, use on human skin may increase the risk of contact transmission [influenza A virus], Thus accelerating the pandemic. ”

The research team tested skin collected from autopsy samples taken about a day after death.
Both coronavirus and influenza viruses can be inactivated within 15 seconds by using ethanol (used in hand sanitizer).
“The longer life span of SARS-CoV-2 on the skin increases the risk of contact transmission; however, hand hygiene can reduce this risk.”
The research supports the World Health Organization’s guidance on regular and thorough hand washing to limit the spread of this virus. Since the virus first appeared in China at the end of last year, the virus has infected nearly 40 million people worldwide.
