Contact transmission through human skin is considered a significant risk factor in the spread of SARS-CoV-2.
There have been other reports studying the stability of SARS-CoV-2 on various surfaces from slaughterhouses, food manufacturing facilities, and even meat, but there had previously no studies on human skin as of yet.
Application of pathogenic and infectious agents to live human subjects is dangerous and not clinically feasible, hence researchers from Japan developed a model to evaluate the stability of the pathogen, using human skin obtained from forensic autopsy specimens ay Kyoto Prefectural University of Medicine.
Published in the Clinical Infectious Diseases journal, researchers commented: “There is no evaluation system at this stage that is more accurate and reproducible than this model.
“We believe this new method has the potential to contribute greatly to the development of infection-control strategies in the future.”
Study design
In this study, researchers collected abdominal skin containing the epidermal and dermal layers, measuring 4 × 8 cm2 from autopsy specimens one day after death.
They explained that the human skin, especially the epidermis has a slower deterioration after death compared to other organs.
In addition to assessing SARS-CoV-2, researchers also conducted the same experiment on influenza A virus (IAV), a common virus also transmitted through droplets.
They investigated the stability of both pathogens on stainless steel, borosilicate glass, polystyrene, and human skin.
