An alarming rise in norovirus cases has been reported across various parts of the U.S., with the Centers for Disease Control and Prevention (CDC) noting 91 outbreaks during the week of December 5, a significant jump from the 69 outbreaks reported at the end of November. This increase follows a trend where between 19 million to 21 million people annually contract the highly contagious stomach bug.
Norovirus is the leading cause of foodborne illnesses and is known for its sudden onset of vomiting and diarrhea. It also causes nausea, stomach pain, headaches, body aches, and fever. The CDC reports that it leads to approximately 900 deaths and 109,000 hospitalizations each year. The virus thrives in crowded environments like nursing homes, schools, and cruise ships, especially during the winter months between November and April.
Experts stress the importance of proper hygiene, such as frequent handwashing with soap and water, to prevent the spread of the virus, as masking does little to stop transmission. With no specific medication to treat it, the virus typically resolves within one to three days, but it remains a significant public health concern.
