Norovirus is a highly contagious stomach bug that can spread quickly. Symptoms include fever, vomiting or diarrhea.

Norovirus outbreaks are usually more common during the winter months. Norovirus is even known as the “winter vomiting bug.” Jenilee Lawrence, MD, provides more information about the virus and advice on what to do if you’ve caught this stomach bug.

Lawrence says that UVA clinics have seen some suspected cases already, even though they don’t specifically test for the virus. Outbreaks in November 2019 made national news. Entire districts of public schools in Colorado had to close as norovirus spread among students. A Norwegian cruise ship had to dock early, and several passengers had to be hospitalized after experiencing severe norovirus symptoms.

Locally, there was a small outbreak among UVA students as they returned to school last January. Norovirus outbreaks typically occur in places where people have close contact with each other like schools, restaurants, long-term care facilities and cruise ships.

What is Norovirus?

Norovirus is a highly contagious virus that spreads very easily and quickly. You can get infected if you touch your nose or mouth after touching an infected object or surface or by consuming contaminated food or water. Norovirus is the leading cause of foodborne illness, but other germs and chemicals can also cause food poisoning.

Norovirus Symptoms

According to Lawrence, you might have a mild illness with watery diarrhea and a fever or more intense symptoms. These include:

“Symptoms usually last for 2-3 days and recovery is usually quick,” Lawrence says.

Around 20 million people get norovirus each year in the U.S. Infected food workers cause about 70% of reported norovirus outbreaks, while cruise ships account for only 1% of cases. However, cruise ship outbreaks get more media attention, and norovirus has even been called “cruise ship virus”.

Winter Cruising: Steering Clear of the Stomach Bug

Are you planning to escape the cold temperatures with a winter vacation cruise? Keep these tips from the CDC in mind, so if norovirus starts to spread on your ship, you can avoid getting ill.

If you do get sick on the ship, be sure to notify the medical staff onboard and follow their instructions. If you’re feeling sick before the trip, get the OK from your doctor before leaving. The CDC tracks norovirus outbreaks on cruise ships and publishes the reports online.

“The best defense against norovirus is proper hand washing with soap and water,” Lawrence says. “I always tell my patients to sing happy birthday twice and that would be the proper amount of time to wash your hands. Keep nails short and clean as well.”

Also, handle and prepare food safely to protect yourself from norovirus.
