Health District Reports Increase in Norovirus
The Southern Nevada Health District is reporting an increase in norovirus detected in community wastewater. Often referred to as the “stomach flu,” norovirus is not related to the influenza virus. It is the leading cause of vomiting, diarrhea and foodborne illness in the United States.
Cases of norovirus typically increase between November and April. The most common symptoms include diarrhea, vomiting, nausea and stomach pain. Other symptoms can include fever, chills, headache, muscle aches and fatigue. Most people who contract the virus recover within one to three days. However, older adults, young children and people with other medical conditions may be at higher risk of severe infections. Frequent vomiting and diarrhea can also lead to dehydration.
Norovirus spreads easily and quickly. People can contract it from direct contact with someone who is infected, such as when caring for them or sharing food or eating utensils. The virus can also be spread by consuming contaminated food or drinks or by touching contaminated objects or surfaces and then putting unwashed hands in the mouth. It is possible to spread norovirus for up to two weeks or more after symptoms have resolved.
The Health District urges the public to take the following precautions to protect themselves and others:
- Wash hands frequently with soap and running water for 20 seconds, especially after going to the bathroom, changing a diaper or before preparing food.
- Thoroughly cook shellfish and wash fruits and vegetables before consumption.
- Clean and disinfect contaminated surfaces after someone is sick.
- Don’t eat food prepared by someone with norovirus or prepare food if experiencing symptoms.
- Stay home if symptoms develop and for an additional two days (48 hours) after symptoms stop.
“As we approach the holiday season people will be spending more time at gatherings with family and friends,” said Dr. Fermin Leguen, District Health Officer for the Southern Nevada Health District. “I encourage everyone to take steps to keep themselves and their loved ones healthy, including getting their updated flu and COVID-19 vaccines if they haven’t already done so.”
