As the U.S. enters the winter months, norovirus outbreaks are making a significant return, with the Centers for Disease Control and Prevention (CDC) reporting a sharp uptick in cases. The latest data from the CDC shows 91 norovirus outbreaks during the week of December 5, 2024, a significant jump from the 69 outbreaks reported the previous week.
Experts cite the post-COVID-19 holiday season as a possible reason for the recent outbreak, with Professor of Infectious Disease Dr. William Schaffner telling Fortune: “It’s really taking advantage of our having gotten together for the first time in several years.”
What is Norovirus?
Norovirus, often referred to as the “stomach flu,” is a highly contagious virus that causes gastrointestinal distress, including vomiting, diarrhea, and stomach cramps. It spreads easily through contaminated food, water, surfaces, and close contact with infected individuals. Health officials are urging Americans to take extra precautions during this time, particularly as the virus is known for its rapid spread, especially in communal settings like schools, nursing homes, and cruise ships.
The CDC’s latest statistics indicate that the virus is particularly prevalent in certain states such as Minnesota, with a growing number of outbreaks across the country. The increase in cases is concerning for public health officials, as the virus spreads quickly in crowded spaces, making it difficult to contain. Although norovirus is not usually life-threatening, it can cause severe dehydration, particularly in vulnerable populations such as the elderly and young children.
Prevent the Spread
Health experts are stressing the importance of proper hygiene and sanitation to help prevent the spread of the virus. One of the most effective preventive measures is frequent handwashing with soap and water. Alcohol-based hand sanitizers are not as effective against norovirus, making soap and water the best defense. Additionally, disinfecting surfaces that may come into contact with the virus, such as countertops, door handles, and light switches, is crucial.
Food safety is another key concern, as the virus can spread through contaminated food or water. Individuals are advised to be cautious when consuming raw or undercooked foods, particularly shellfish. Although foodborne outbreaks of norovirus have been reported, proper handling and cooking can significantly reduce the risk of infection.
Health officials also emphasize the importance of staying home if you are feeling sick. Those experiencing symptoms of norovirus should avoid contact with others to prevent further spread of the virus. Anyone who develops symptoms should stay home for at least 48 hours after their symptoms subside to reduce the risk of infecting others.
The CDC continues to monitor the situation closely as norovirus cases rise across the country. Health experts are urging the public to take precautions and remain vigilant in practicing good hygiene and food safety, particularly as the winter season brings people together in shared spaces for the holidays.
With more outbreaks expected in the coming weeks, health officials are reminding everyone that by taking simple steps—such as washing hands, disinfecting surfaces, and staying home when sick—they can help reduce the spread of norovirus and protect themselves and others during this ongoing surge.
