He coronavirus remains active on human skin for 9 hours, 5 times more than the flu virus, according to a group of Japanese researchers, whose The study was published this month in the journal Clinical Infectious Diseases.
By comparison, the pathogen that causes the flu survives on human skin for about 1.8 hours, research indicates.
“The 9-hour survival of SARS-CoV-2 [el virus que causa la COVID-19] on human skin may increase the risk of contact transmission compared to IAV [virus de la gripe A], thus accelerating the pandemic ”, says the study.
The research team examined the skin obtained from autopsies, approximately one day after death.
As he coronavirus like the flu virus they are inactive 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 contact transmission; however, hand hygiene can reduce this risk ”, adds the study.
These findings support the recommendations of the World Health Organization (WHO) to regularly wash your hands thoroughly to limit the transmission of the coronavirus, habit that could prevent many other diseases, as recommended by Pulzo in a recent article about World Handwashing Day.
Regarding the resistance of the coronavirus on certain surfaces, last weekend a study by the Australian National Science Agency was known, according to which the virus can survive up to 28 days on cell phone screens and plasticized bills.
