CDC Reports Doubling of Norovirus Cases in the U.S. Since August
The Centers for Disease Control and Prevention (CDC) has reported a significant increase in norovirus cases across the United States, with the rate of positive tests doubling since August. As of the most recent data, nearly 14% of tests for norovirus have returned positive, compared to approximately 7% three months ago. Norovirus, often referred to as the 'stomach bug,' is a highly contagious virus and the leading cause of viral gastroenteritis in the U.S. It is responsible for 58% of foodborne illnesses annually. The virus causes symptoms such as nausea, vomiting, stomach pain, and diarrhea, and typically resolves within one to three days in healthy adults. The CDC emphasizes the importance of handwashing with soap and water to prevent the spread of the virus, as hand sanitizers are not effective against it.
