Cases of the highly contagious norovirus are surging across the United States this winter, with health officials reporting a striking increase in outbreaks. The (HuffPost) cites the Centers for Disease Control and Prevention (CDC) statistics which revealed that there were 91 outbreaks reported during the week of December 5, an increase from 69 outbreaks the prior week. This figure considerably exceeds the three-year average of 65 outbreaks for early December.

Norovirus, often referred to as the "winter vomiting bug," is the leading cause of foodborne illness in the U.S., responsible for approximately 58% of foodborne infections each year. The virus can cause sudden and severe gastrointestinal symptoms, including vomiting, diarrhea, nausea, and stomach pain (source: India Times). Transmission typically happens through direct contact with infected individuals, contaminated food, or surfaces.

According to the CDC, norovirus is especially prone to outbreaks in crowded venues such as cruise ships, nursing homes, and schools. It is vital for the public to be aware that even a small number of viral particles, as few as ten, can lead to infection. Health experts estimate that each year, norovirus results in between 19 to 21 million illnesses in the U.S., leading to about 900 deaths and over 109,000 hospitalizations, highlighting its significant impact on vulnerable populations like young children and the elderly.

Symptoms typically manifest within 12 to 48 hours after exposure, with most individuals recovering within one to three days. However, the risk of dehydration, especially in children and the elderly, is a critical concern (source: Independent).

To mitigate the spread of norovirus, health experts recommend rigorous handwashing with soap and water for at least 20 seconds, particularly before meals, and cleaning surfaces with disinfectants. There is currently no specific medication to treat norovirus, but staying hydrated is essential to recovery (source: Salon).
