Cases of norovirus, commonly known as the stomach flu, are on the rise according to recent data from the Centers for Disease Control and Prevention (CDC). The virus is present throughout the year, though its prevalence typically increases during the winter months.
At the University of Arkansas for Medical Sciences (UAMS), officials note that norovirus tends to spread easily in crowded environments, with the holiday season being a peak time as people gather in homes. While outbreaks on cruise ships often make headlines, the virus can also affect other places like daycares and nursing homes, especially when large groups are in close contact.
Though norovirus can affect people of all ages, its impact is often more severe in younger children and the elderly, who are more susceptible to dehydration. These groups require particular attention, as dehydration can escalate quickly in these populations.
As the leading cause of foodborne illness in the United States, norovirus causes symptoms such as vomiting, diarrhea, and nausea. Health experts recommend allowing the virus to run its course, but advise seeking medical attention if severe dehydration occurs. This is especially important for children and older adults who are unable to keep fluids down, in which case a visit to the doctor may be necessary after a day of persistent symptoms.
To reduce the risk of contracting norovirus, experts emphasize the importance of frequent handwashing, avoiding shared food and utensils, and steering clear of raw or undercooked shellfish.
