Norovirus is a highly contagious virus that leads to acute gastroenteritis, marked by severe vomiting and diarrhea. Despite being sometimes called the stomach flu, it is distinct from influenza, according to the CDC.
Symptoms and Onset
Symptoms typically appear 12 to 48 hours after exposure and can be extremely debilitating. Frequent vomiting and diarrhea are common, though most individuals recover within one to three days. The illness poses a significant risk of dehydration due to rapid fluid loss, especially in vulnerable populations such as young children, older adults, and those with underlying health conditions.
Who Is at Risk?
Anyone can contract norovirus, with outbreaks affecting people of all ages. An individual's genetic predisposition can influence their likelihood of infection. Raw oysters and other filter-feeding shellfish are common sources. While anyone consuming them is at risk, children under five, older adults, and those with weakened immune systems are more prone to developing severe infections.
Recent Outbreak
In a related incident, France stopped 1,700 passengers from disembarking a cruise ship after a suspected norovirus outbreak.
Prevention Tips
- Wash hands frequently with soap and water, especially after using the bathroom or before eating.
- Avoid preparing food for others if you are sick.
- Clean and disinfect surfaces with bleach-based cleaners.
- Wash fruits and vegetables thoroughly and cook shellfish completely.
- Stay hydrated if infected; seek medical help if dehydration symptoms occur.
By following these steps, you can reduce the risk of infection and protect those around you.
