Study: Covid lasts 9 hours on the skin, 5 times more than the flu

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

“Prolonged presence of SARS-CoV-2 on the skin increases the risk of contact-transmission; However, hand hygiene can reduce this risk, ”the study said.

The study supports the World Health Organization’s guidelines for regular and thorough hand washing to limit the transmission of the virus, which has infected nearly 40 million people worldwide since it first appeared in China late last year.
