Washington: Those worried about the coughing and sneezing associated with the upcoming flu season, should consider boosting the humidity in the rooms around you.Moderate to high humidity can significantly reduce the infectivity of influenza virus particles, according to a new study.Maintaining relative indoor humidity at 43 percent or higher could cut the bug`s threat to about 15 percent, researchers found.John Noti and colleagues from the National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention, tested the effect of relative humidity on the capacity of flu virus released in a simulated `cough` to re-infect cells.
