According to scientists at a similar temperature and lack of sunlight “half-life” of the particles on the surface is 6 hours at 80 percent humidity and 18 hours at 20-percent, and in the air (with a humidity content of 20 percent) is about 60 minutes.
The results of the study have not yet been published. Experts NBACC emphasize that the chain of transmission of the causative agent COVID-19 there are still unknown parts.
