The higher the humidity is, the more difficult the flu virus gets distributed, says a group of U.S. scientists. Humidity can be used to protect against flu.
Experts have found that if the humidity in the room is 43% or more, the risk of transmission of the virus from the patient to a healthy person is reduced to 15%. At high humidity (60%) the risk of spreading the flu virus is lowered by 40-50%.
The study was organized by the Center for Disease Control and Prevention USA, whose experts are looking for a way to lower the negative impact of influenza epidemics to the economy. They found that in a relatively dry environment with humidity less than 23%, significant parts of the virus (70-77%) can survive and remain active during one hour. If the humidity rises to 43%, only 14% of the viruses can survive for a moment, and thereby retain the ability to infect humans.
At high humidity most of the viruses die within 15 minutes after incorporation into the environment. Thus significantly reducing the risk of a man infected. Experts advise employers that if they want to reduce the number of workers affected during the flu epidemic should maintain high humidity in the areas when the employers work. This also applies to schools and colleges where probability that the flu spreads from human to human is very high.
Each year, the flu epidemic costs the American economy billions of dollars. In addition, it threatens the health of every individual. High fever and intoxication leave a mark on the organism, although it is often not visible to the naked eye. They recommend a simple and effective way to reduce the risk of infection.
Few people know that the majority of influenza infections happen in enclosed spaces (90%). In cold weather the streets virus can not survive more than a few minutes. In order to avoid a major epidemic we should make our room harmless with frequent wetting and ventilation air.
