Genesee County, MI — The Genesee County Health Department (GCHD) is committed to safeguarding the health and wellbeing of our community. In light of a recent increase in gastrointestinal illness, including norovirus (viral gastroenteritis), we are reaching out to remind everyone of the precautions that can be taken to protect themselves and others from illness.

The viruses that cause gastrointestinal issues can be easily spread by infected people to others, contaminated food, or drinks, aerosolization (of vomited material), or contaminated surfaces and objects. Individuals can reduce their risk of becoming ill through frequent hand washing using soap and warm water for a minimum of 20 seconds, safe food handling and good hygiene.  It is important to note that hand sanitizers, while beneficial for other purposes, are NOT effective against norovirus. By collectively taking these steps, we can protect ourselves and those around us from the spread of illness.

Norovirus, often mistakenly referred to as stomach flu, is the most common cause of vomiting and diarrhea, and foodborne illness in the U.S., and it spreads quickly. Outbreaks can happen anytime, but they occur most often from November to April. Norovirus is NOT related to the flu (influenza), which is a respiratory illness caused by a different virus.

Symptoms normally include: Nausea, vomiting, diarrhea and stomach pain

Other symptoms include: Low-grade fever, headache, fatigue and muscle aches

Norovirus is highly contagious, can live on surfaces for up to two weeks and can be easily spread from person-to-person, especially in group settings, such as gatherings, daycares/schools, restaurants and nursing homes. Most people recover within 1 to 3 days but can continue to shed the virus in their feces for several days to weeks after their symptoms disappear. Anyone showing symptoms such as vomiting and diarrhea should not go to daycare, school, or work for at least 2 days after symptoms stop. There is no specific treatment for norovirus. Individuals with severe diarrhea or vomiting should drink plenty of liquids to replace fluid loss and prevent dehydration. If someone is experiencing symptoms of dehydration, they should seek medical help.

“The best defense against gastrointestinal illnesses, such as norovirus, is frequent handwashing, especially before eating or preparing any food and after using the bathroom or changing diapers,” said Michelle Estell, Interim Health Officer at GCHD. “By practicing good hygiene habits and following preventative guidelines, we can collectively reduce the risk of transmission and protect the health and well-being of our community members.”

Preventing contamination of food, drinks and surfaces is critical to preventing the spread of norovirus. Anyone with norovirus symptoms should wait at least 48-72 hours after their last episode of vomiting and/or diarrhea before preparing food for others. It is important to carefully wash fruits and vegetables before preparing and eating them. The spread of norovirus can be prevented by disinfecting contaminated surfaces with bleach-based cleaners and prompt washing of contaminated articles of clothing and linen.

GCHD is committed to enhancing community well-being in Genesee County by preventing disease, promoting health, and protecting against environmental hazards. Our mission focuses on creating a healthier, safer environment for all residents. For further information, visit geneseecountymi.gov.
