Norovirus Cases Surge Ahead of Holidays, CDC Warns
Published November 27, 2025 – As the holiday season approaches, health officials are sounding the alarm about a significant increase in norovirus cases across the country. The highly contagious virus, known for causing vomiting and diarrhea, is spreading rapidly, posing a threat to festive gatherings.
Norovirus is a major concern for those who have contracted the virus. Symptoms of dehydration,a common complication,include urinating less frequently or having dark-colored urine,dry mouth,weakness,dizziness,and headache.
Individuals infected with norovirus typically experience symptoms suddenly. Children may exhibit fussiness, excessive sleepiness, and cry without tears. Symptoms generally appear 12 to 48 hours after exposure and last one to three days.
While some individuals may experience unpleasant symptoms, others can be asymptomatic yet still contagious, capable of spreading the virus to others. The Centers for Disease Control and Prevention (CDC) notes that children younger than 5, older adults, and people with weakened immune systems are at higher risk of developing severe infections.
How Norovirus Spreads
Norovirus is easily transmitted through close contact with infected individuals (even those without symptoms), by touching contaminated surfaces and then touching the mouth or nose, and most commonly, by consuming contaminated food or beverages.
The virus is notoriously arduous to kill,resisting both hot and cold temperatures and many common disinfectants. It can easily spread when an infected person, or someone who has touched contaminated surfaces, handles food being prepared or served.
Protecting Your Holiday
Health officials emphasize the importance of diligent handwashing, especially for those preparing holiday meals.”Wash your hands with hot, soapy water for at least 20 seconds and do it often,” officials advise. “Wash them before and after eating, before and after handling food and after using the bathroom.”
Beyond hand hygiene, general food safety practices are crucial. food should be cooked thoroughly to the designated internal temperature (at least 145 degrees Fahrenheit is a general guideline). Frequently touched surfaces and objects, particularly those in contact with food, should be cleaned and sanitized regularly. Fruits and vegetables should be washed before serving or consumption.
The CDC recommends that anyone feeling sick should refrain from attending family gatherings for at least two days after symptoms have subsided. During this time,individuals should avoid close contact with others,refrain from handling food,wash their hands frequently,and thoroughly clean up any bathroom messes.
