Higher Indoor Humidity Levels Might Slow Flu's Spread

THURSDAY, Feb. 28 (HealthDay News) -- As the flu season continues to pack a punch for some Americans, new research suggests there might be a simple way to reduce the risk for infection in an indoor setting: hike up humidity levels.

By raising indoor relative humidity levels to 43 percent or above, investigators reported that they were able to quickly render 86 percent of airborne virus particles powerless.

The finding is reported in the February issue of the journal PLOS One by a team led by John Noti, a senior service fellow with the U.S. National Institute for Occupational Safety and Health's Health Effects Laboratory Division at the U.S. Centers for Disease Control and Prevention in Morgantown, W.V.

To assess the role of humidity in flu transmission, Noti and his colleagues relied on mechanized mannequins and tissue cultures rather than actual humans.

Placed in a tightly sealed and disinfected model of a hospital examination room, a coughing mannequin served as a flu patient and was outfitted with aerosolized viral solution. The viral solution was projected into the air via five mechanized "coughs," spread out over one-minute intervals.

At the same time, a breathing mannequin (serving as a caregiver) was set to face the coughing mannequin at a distance of a little less than 7 feet. The breathing model was programmed to inhale in sync with the coughing, and aerosol samples of inhaled air were collected at various points around the mouth of the caregiver for up to five hours post-coughing.

Throughout testing, humidity levels were adjusted from a low of 7 percent relative humidity to a high of 73 percent.

The result: the team found that when humidity levels were set to 43 percent, only 14 percent of the virus particles that were released were able to transmit the influenza virus, compared with a transmission rate of 70 percent to 77 percent in a re
