The new coronavirus survives on human skin five times longer than an influenza virus, 9 hours versus 1.8 hours, according to the study published in the scientific journal Clinical Infectious Diseases Journal. “The 9 hour lifespan of SARS-CoV-2 on human skin increases the risk of transmission by contact with respect to the influenza virus, accelerating the pandemic”, state the Japanese researchers.
They studied the resistance of the virus on the skin of recently deceased people.
Both the coronavirus and the flu virus are “deactivated” within 15 seconds when using ethanol, contained in hand gels. The longer the new coronavirus stays on the skin, the greater the risk of spreading, the researchers point out. “Hand hygiene can reduce this risk,” they add.
