Air humidity control transmission of influenza virus, says study Researchers have found low correlation with the absolute humidity.
Apparently, weather conditions favor viral particles.
The waves of influenza that shook the world during winter are directly related to the level of absolute humidity of the air, says a new survey: the lower, the stronger becomes the transmission of the virus causing the disease. The conclusion is the American researchers Jeffrey Shaman, the University of the State of Oregon, and Melvin Kohn, Department of Health Services of Oregon, in an article in the scientific journal 'PNAS'.
Before the study, researchers had tried to find a correlation between the progression of influenza virus and the low relative humidity (which refers not to the total amount of water vapor in the atmosphere, but the level of humidity depends on temperature air). The new study shows that important really is the absolute humidity of air, and that apparently the virus particles can survive for longer when the weather is cold and dry. That would explain the ease of transmission of disease in these conditions.
