Corona infections also possible through contact transmission
SARS-CoV-2 viruses survive longer in the mucus
Coronaviruses can survive on human skin for up to nine hours. This is the result of a new study by Japanese scientists. In the study, the Japanese research team applied both corona and influenza viruses to human skin to check how long the viruses remained active on it. For comparison: Influenza A type flu viruses only survived two hours on the skin. In another experiment, the scientists mixed the SARS-CoV-2 viruses with mucus to simulate transmission when sneezing or coughing. The result: the viruses remained active on the skin for up to 11 hours!
Researchers warn: hand hygiene remains important
“The nine-hour survival time of SARS-CoV-2 on human skin could mean an increased risk of contact transmission compared to the influenza A virus,” the authors conclude in the study published in the journal “Clinical Infectious Diseases”. The good news: after the researchers applied an ethanol-based disinfectant to the infected areas of the skin, all viruses were completely killed within 15 seconds. Their study results suggested, the researchers say, the importance of thorough hand hygiene to prevent the virus from spreading.
