Influenza, or flu, viruses cause about 200,000 hospitalizations every year in the U.S. Annual seasonal vaccination is our best line of defense, but in recent years, it has become clear that mismatches in the vaccine can limit its effectiveness.
We study how the flu virus spreads between people. While we strongly encourage everyone to get the flu vaccine, the findings from our study on the stability of flu viruses in the air can provide useful information for parents, teachers, and health care officials to limit the spread of flu in the community.
By employing simple strategies to reduce the amount of flu virus in our environment, we can decrease the number of infections every year.
