The new corona remains on the skin five times longer than influenza, but there is also a way to deactivate it in 15 seconds

Studies have shown that the new coronavirus (SARS-CoV-2) spreads by contact in addition to flying, and remains on hard, smooth surfaces such as plastic and glass for up to 72 hours. I will . A new paper published by a research team at Kyoto Prefectural University of Medicine showed that SARS-CoV-2 remains on the skin for up to 9 hours, five times longer than the influenza virus.

The research team conducted an experiment using skin samples from people who died from infection with SARS-CoV-2 within 24 hours. When the skin cell sample of COVID-19 patient and the skin cell sample of influenza A were mixed and the remaining time of each was measured, it was shown that SARS-CoV-2 remained on the skin for 9.04 hours. 9.04 hours is shorter than the residual time of SARS-CoV-2 on the surface of plastic or glass, but the influenza virus was 1.82 hours, which is about 4.96 times longer.

'This result shows that SARS-CoV-2 is much longer stable (than the influenza virus) on human skin,' the research team said.

When mixed with mucus collected from upper respiratory tract samples, SARS-CoV-2 remained for up to 11.09 hours, whereas influenza virus remained for 1.69 hours. In other words, it remains on the mucus about 6.5 times longer than the influenza virus.

On the other hand, experiments have also shown that the use of disinfectants with an alcohol content of 80% or more completely inactivates all viruses within 15 seconds.

Both SARS-CoV-2 and influenza virus are transmitted by flying and contact, but the research team concludes that SARS-CoV-2 is much more stable on the skin than influenza virus and therefore has a higher risk of infection. It is attached. It is expected that the second and third waves of SARS-CoV-2 will occur from autumn to winter, but the research team is calling for proper cleaning and disinfection of fingers.
