Norovirus is the No. 1 cause of foodborne illness in the United States. And while most people who contract norovirus recover on their own without the need for testing or treatment, others do not. 

In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Department of Laboratory Medicine and Pathology at Mayo Clinic, and William Morice II, M.D., Ph.D., president and CEO of Mayo Clinic Laboratories, discuss what’s behind recent outbreaks of norovirus and how to keep yourself healthy and protected throughout the remainder of this year’s peak norovirus season.
