US, WASHINGTON (ORDO NEWS) — With a relative air humidity of 40 to 60 percent, SARS-CoV-2 coronavirus is transmitted less often from healthy patients than in conditions of lower or higher humidity. Relevant data published on Yale University website.
Studies have shown that infected rodents often transmit viral particles through the air to uninfected neighbors in low humidity conditions.
Scientists note that dry air greatly simplifies the movement of the virus in the room, and also weakens the ability of the respiratory tract to remove viral particles. In addition, the ability of the immune system to respond to pathogens is suppressed in drier conditions.
At the same time, experts point out that too high humidity, for example in the tropics, also creates favorable conditions for the spread of the virus, since it allows virus particles to settle on surfaces more often.
Researchers recommend using indoor humidifiers and maintaining 50 percent air humidity.
At the same time, scientists recall that such a precaution helps to reduce the risk of transmission of the virus by air, but not by drip, and reminds about the need to wash your hands and disinfect surfaces.
The new coronavirus causing the COVID-19 disease has already affected nearly 200 countries. According to the WHO, in total more than 690 thousand cases of infection were recorded, 33 thousand people died. According to statistics from Johns Hopkins University, there are more cases and victims.
