Norovirus cases are on the rise in the United States, with 455 outbreaks reported since the beginning of September. The first week of December saw more than 90 outbreaks, one of the highest rates recorded since data collection began in 2012. However, the actual number of outbreaks is likely higher as only 14 states contribute to the CDC’s NoroSTAT reporting system.
The surge in norovirus cases is also reflected in the increasing rate of positive tests for the virus across the country. From the week ending Nov. 16 to the week ending Dec. 21, there was a sharp rise from 10.6% to 22.02%. Similar high case numbers have been reported in other countries, including the U.K.
Typically, around 2,500 norovirus outbreaks are reported annually in the U.S., with the majority occurring between November and March and peaking in February. Experts suggest that the disease may be spreading earlier this year due to increased socialization.
Norovirus, also known as the “winter vomiting bug,” is a highly contagious illness that causes gastrointestinal symptoms. It is responsible for more cases of vomiting, diarrhea, and foodborne illness than any other disease in the country. The virus spreads through contact with infected individuals, contaminated surfaces, or tainted food and drinks.
Symptoms of norovirus include nausea, stomach pain, vomiting, diarrhea, headaches, fever, and body aches. Dehydration can be a concern due to vomiting and diarrhea, so it’s essential for individuals with the virus to stay hydrated by drinking small, frequent sips of water.
Preventing norovirus involves frequent hand-washing, especially after using the bathroom or caring for someone with the illness. Cleaning high-touch surfaces, washing clothes and sheets at high temperatures, and cooking shellfish thoroughly can also help reduce the risk of infection. Avoiding raw shellfish like oysters is recommended by the CDC to prevent illness and potential death.
In conclusion, staying vigilant with hygiene practices and taking necessary precautions can help protect against norovirus and reduce the spread of the virus during this surge in cases.
