Las Vegas, NV (KXNT) – 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.
