Norovirus cases surge as CDC reports 91 outbreaks in one week

In the United States, norovirus cases have surged significantly, according to data shared by the CDC. This highly contagious virus is the leading cause of foodborne illness in the country, responsible for approximately 2,500 reported outbreaks annually. Symptoms of norovirus infection include diarrhea, vomiting, nausea, and severe stomach pain, which can occur suddenly and last between 12 to 47 hours. The increase in cases comes as health departments noted a rise from 69 outbreaks to 91 within a week, indicating a growing challenge especially during peak months from November to April. Norovirus spreads quickly through contaminated food, water, surfaces, and direct contact with infected individuals. Even small amounts of the virus can cause infection, which is particularly problematic in settings like cruise ships where outbreaks are common. Hospitals often fail to test for norovirus, which means many cases go unreported, leading to an underestimation of its actual prevalence. The authorities emphasize the importance of hygiene, advising people with symptoms to refrain from food preparation and to wash their hands frequently to limit the spread. Despite symptoms often resolving without intervention, medical advice is crucial in certain situations. If individuals cannot maintain hydration or experience severe symptoms, such as prolonged vomiting or diarrhea, they should contact a healthcare professional. Preventative measures are highlighted, including staying home when sick, which is essential in controlling outbreaks among family members and the larger community. As norovirus continues to circulate during this peak season, understanding its transmission routes and symptoms is vital for effective prevention. Education on proper hygiene practices and recognizing when to seek medical attention can help mitigate the impact of this illness as we move further into winter months.
