There has been a notable increase in cases of the highly contagious stomach bug Norovirus in the northeastern United States, as outlined in a recent update from the Centers for Disease Control and Prevention (CDC).
The agency shared that around 16% of the latest Norovirus tests in the region came back positive, surpassing the national average of 12%. By contrast, the Midwest and South had a reported increase of close to 10%, while the West saw an increase of nearly 13%.
Norovirus: The Contagious ‘Stomach Bug
Commonly referred to as the “stomach bug,” norovirus is a highly contagious virus that leads to gastroenteritis, which is the inflammation of the stomach and intestines.
It is considered the primary cause of acute gastroenteritis worldwide, with symptoms such as diarrhea, vomiting, nausea, and stomach cramps.
The virus can be transmitted through contaminated food, water, surfaces, and close contact between individuals.
While Norovirus infections usually resolve on their own within a few days, they can be serious, especially in vulnerable populations like young children, the elderly, and those with weakened immune systems.

Norovirus: Fast Onset, Contagion Risks, and Hydration Tips
Norovirus can be spread through person-to-person contact, contaminated food or water, and surfaces.
Because of its high contagion, becoming ill can result from just one handshake or touching a contaminated surface.
Norovirus illness strikes suddenly and dramatically, with symptoms emerging within hours and usually persisting for two to three days.
Although most individuals make a full recovery, dehydration is a significant issue, especially for young children, older adults, and individuals with compromised immune systems. It is essential to replace fluids with water, soda, or other non-caffeinated and non-alcoholic beverages.
Norovirus Signs and Prevention Tips
Signs of Norovirus infection consist of acute gastroenteritis symptoms, like sudden onset diarrhea, vomiting, nausea, and stomach cramps.
Some people might also have a low-grade fever, headache, muscle aches, and fatigue. Typically, symptoms appear within 12 to 48 hours of exposure and last for 1 to 3 days.
To effectively protect against Norovirus infection, it is crucial to consistently wash your hands with regular soap and warm water for a minimum of 20 seconds before eating.
Experts recommend cleaning surfaces with household disinfectants and practicing good sanitation to help prevent infection.
