Norovirus Cases Are Up in Pockets of the U.S.
By India Edwards HealthDay Reporter
MONDAY, Dec. 30, 2024 -- Norovirus, a highly contagious stomach bug, is surging across the United States this winter, according to the latest data from the U.S. Centers for Disease Control and Prevention (CDC).
The data shows 91 outbreaks of norovirus during the week of Dec. 5, a sharp rise from the 69 outbreaks recorded the previous week.
For context, the first week of December has typically seen a maximum of 65 outbreaks in recent years.
Often called the "stomach flu," norovirus causes sudden vomiting, diarrhea, and other gastrointestinal symptoms.
Outbreaks tend to occur in crowded settings such as nursing homes, schools, jails, and cruise ships.
The report comes after a recent outbreak that infected over 300 individuals onboard three different cruise ships earlier this month.
Norovirus spreads rapidly through direct contact with infected individuals or contaminated food, water, or surfaces. Sharing food, drinks, or utensils with someone infected can also transmit the virus.
Symptoms usually appear 12 to 48 hours after exposure and last for one to three days. While most people recover fully, dehydration from vomiting and diarrhea can be dangerous, particularly for young children, older adults, and those with weakened immune systems.
The best defense against norovirus is frequent and thorough handwashing with soap and warm water for at least 20 seconds, especially before meals. Disinfecting surfaces with household cleaners can also reduce the risk of infection.
If symptoms of dehydration occur -- such as dry mouth, dizziness, or decreased urination -- seek medical attention. Rehydration with water is key. Avoid coffee, tea, and alcohol, which can worsen dehydration.
