The novel coronavirus can survive for up to several hours on human skin, according to a new study published in the journal Clinical Infectious Diseases.

In laboratory experiments, researchers found that the virus survives for nine hours, four times longer than the influenza A virus can live for.

Team obtained human skin from forensic autopsy specimens 24 hours prior and mixed skin cells with samples of coronavirus and influenza virus A. Evaluated stability of SARS-CoV-2 and influenza A virus (IAV), mixed with culture medium or upper respiratory mucus, on human skin surfaces and the dermal disinfection effectiveness of 80% (w/w) ethanol against SARS-CoV-2 and IAV.

RESULTS:

• SARS-CoV-2 and IAV were inactivated more rapidly on skin surfaces than on other surfaces (stainless steel/glass/plastic. Survival time was significantly longer for SARS-CoV-2 than for IAV [9.04 h vs. 1.82 h].

• IAV on other surfaces was inactivated faster in mucus versus medium conditions, while SARS-CoV-2 showed similar stability in the mucus and medium. Survival time was significantly longer for SARS-CoV-2 than for IAV [11.09 h vs. 1.69 h].

• Moreover, both SARS-CoV-2 and IAV in the mucus/medium on human skin were completely inactivated within 15 s by ethanol treatment.

CONCLUSION:

• 9-h survival of SARS-CoV-2 on human skin may increase the risk of contact transmission in comparison with IAV, thus accelerating the pandemic. Proper hand hygiene is important to prevent the spread of SARS-CoV-2 infections.
