Norovirus Cases Are Rising — Here's How To Prevent It From Spreading

“Isolating to one location and one bathroom that can be thoroughly cleaned is the best route of prevention,” Joy said. 

This option is of course more feasible if the infected person is an adult or older child and if you live in a home with multiple bathrooms and ample private spaces. 

“It’s often much easier to isolate adults and make sure that they are thoroughly washing their hands,” Joy noted. “Sick children often want to be held, causing more direct contact with the virus. If possible, identify one member of the household to care for the child, limiting the risk of spread throughout the entire household.”

Those who are infected should stay at home, even if their illness is starting to improve. 

“The key for your household member is keeping them hydrated with rehydration solutions that are available,” said Dr. Jason Newsland, division chief of infectious diseases at Nationwide Children’s Hospital.

If they become too dehydrated, he noted that they should go to an emergency department or urgent care where they can get intravenous fluid.

“There is no specific medication to treat norovirus, but your provider may recommend over-the-counter anti-diarrheal or anti-nausea medication,” Joy said. “Most people with norovirus feel better within one to three days, but should remain home from school or work until symptoms fully resolve.”

Clean, clean, and keep cleaning.
