The Wyoming Department of Health (WDH) has reported a rise in norovirus cases statewide, citing elevated levels detected in wastewater testing since mid-December, Buckrail reports.
Often referred to as the “stomach flu” or “food poisoning,” norovirus is a common cause of gastrointestinal illness and is known for its highly contagious nature.
According to the WDH, norovirus is responsible for a significant number of recent illnesses in Wyoming. The virus can spread through contaminated food, surfaces, or close contact with an infected individual.
“Norovirus, a familiar and repeat offender, is responsible for many recently increased reports of illnesses in Wyoming,” the department stated in a press release.
Matt Peterson, WDH surveillance epidemiologist, emphasized the challenges of preventing contamination, noting that even a clean-looking kitchen or restroom could harbor tiny amounts of infectious material.
“We can’t always see what can unfortunately make us very sick,” Peterson said.
Symptoms of norovirus typically develop 12 to 48 hours after exposure and include nausea, vomiting, watery diarrhea, stomach cramps, fatigue, and dehydration. While most cases resolve within one to three days without long-term complications, severe dehydration can pose a serious risk, particularly for vulnerable groups such as infants, young children, the elderly, and immunocompromised individuals.
“People who become severely ill should seek medical attention,” Peterson advised.
He added that hospitalization may be necessary in extreme cases.
To help prevent the spread of norovirus, the WDH recommends the following practices:
- Wash hands thoroughly with warm water and soap, especially after using the restroom, changing diapers, or before handling food.
- Stay home if experiencing symptoms, particularly if working in food-handling, healthcare, or childcare roles.
- Minimize contact with others while ill and practice good hygiene.
- Clean and disinfect contaminated surfaces with a bleach solution (one cup of household bleach per gallon of water).
- Properly wash contaminated clothing and linens in hot water and soap.
Peterson also warned that individuals can remain contagious for several days after symptoms subside, underscoring the importance of continued hygiene precautions.
