Study Finds One Thing Reduces Spread of Cold & Flu in Preschool

Published Date: 11/04/19

Flu and cold season can be difficult on any daycare or preschool. Children may not use proper techniques to contain their sneezes and coughs, share food, and generally, spread germs throughout your facility. Regardless of how well you clean, viruses will likely leave many of your kids sick - and unfortunately you and your staff as well.

However, researchers may have found a simple, inexpensive technique to help prevent the spread of colds and the flu in hospitals - and how it can impact preschools.

Lead by Harvard Medical School graduate Dr. Stephanie Taylor, researchers explored how infections spread within hospitals, despite the fact that hospitals have many preventative measures in place. They tried to isolate factors associated with patient infections when looking at 370 patients in one unit of a hospital. While controlling for every possible variable they could think of to influence the likelihood of infection, they tested 8 million data points.

Researchers considered the hygiene of patient visitors, room cleaning procedures, how frail a patient was, all which had some impact on likelihood of infection. However, there was one circumstance that stood out above the rest as a contributing factor to the spread of viruses and that was the dryness of the air. When humidity was low outside, indoor air was strongly associated with higher infection rates.

“When we dry the air out, droplets and skin flakes carrying viruses and bacteria are launched into the air, traveling far and over long periods of time. The microbes that survive this launching tend to be the ones that cause healthcare-associated infections,” said Taylor. “Even worse, in addition to this increased exposure to infectious particles, the dry air also harms our natural immune barriers which protect us from infections."

A team of researchers at the Mayo Clinic also tested this theory in a preschool. Over the three-month winter, they left half the classrooms in the preschool untouched, but humidified the other half. The results were astounding. Children were absent two-thirds less from influenza in the humidified classrooms than in the ones left alone.

More research is being funded by National Institutes of Health (NIH) on the topic, but Taylor says every home, school, and hospital should have a hygrometer, which tests the relative humidity in the room, and a humidifier to adjust the room’s hydration as needed. The sweet spot for indoor air is 40%-60% relative humidity.

Hygrometers are available for less than $20 and the cost of humidifiers ranges depending on your needs. Both warm-mist and cool-mist humidifiers are equally effective in adding moisture to the air, but for safety reasons, always use cool-mist humidifiers around children. Remember to clean them properly according to the manufacturers directions to prevent mold growth and change filters periodically, if the one you choose uses them.
