What to know about norovirus?

A physician and clinical faculty member in family medicine at Tufts University School of Medicine offers advice on how to treat norovirus at home and when to see a doctor
Norovirus spreads when droplets from an infected person’s vomit and feces are ingested by someone else. It can’t spread through inhalation of particles, or through coughing or sneezing, says St. Louis. The best way to prevent the spread of norovirus once you’re sick is to isolate yourself from others, and, especially, to use a different bathroom. “Norovirus is extremely contagious,” he says. “It's very easily transmitted to others. And unfortunately, when someone's having profuse vomiting and diarrhea, it's pretty hard to not be exposed to norovirus particles.”
