Norovirus Cases Rising Across the Country: Health Officials Warn of Contagious Outbreak
Health officials are noting a significant rise in norovirus cases nationwide, prompting warnings of potential outbreaks across the country. The Centers for Disease Control and Prevention (CDC) reports that although positive testing rates are lower compared to the same period last year, the common virus is spreading rapidly, particularly affecting the Northeast region.
Recent alerts from Rhode Island advised against consuming raw oysters from specific regions in Mexico after over 200 individuals were affected by suspected norovirus cases, bringing attention to the severity of the outbreak.
Norovirus, a highly contagious gastrointestinal illness often mistaken for stomach flu or food poisoning, typically manifests with symptoms like vomiting, diarrhea, nausea, and stomach cramps. The CDC asserts that it is the primary cause of foodborne illnesses, emphasizing that it is not linked to the flu.
Symptoms of norovirus usually emerge within 12 to 48 hours post-exposure, including diarrhea, vomiting, nausea, and abdominal pain. Individuals may also experience fever, headaches, and body aches as the virus causes inflammation in the stomach and intestines—a condition known as gastroenteritis.
The virus, which can last up to two days, poses a heightened risk of dehydration, particularly in children, older adults, and immunocompromised individuals. Dehydration indicators include reduced urination, dry mouth/throat, and dizziness when standing.
While the virus is commonly transmitted in educational institutions, childcare facilities, and nursing homes, the CDC warns that anyone can contract it through contaminated food, liquids, surfaces, or direct contact with an infected person.
Amid elevated national cases, the Northeast experiences the highest positive testing rates, with over 13% of norovirus tests returning positive results. Western states are also witnessing around a 12% positive rate, while Southern and Midwestern states hover around 10%.
Preventive measures against norovirus include regular handwashing, thorough produce rinsing, and proper shellfish cooking. Health experts recommend staying home until symptoms subside if diagnosed to prevent further spread of the illness.
