New norovirus strain is stoking the stomach flu surge

This winter’s dominant norovirus strain is a newer variant called the G11.17 [P17]. Jan Vinje, head of the Centers for Disease Control and Prevention’s CaliciNet system, told CBS that the strain is behind outbreaks “everywhere” across the U.S. this winter.

However, Vinje added it was “too early to tell” if the strain is associated with a more severe norovirus disease. Vinje told CBS: “Likely lower population immunity is the reason for the early surge of an otherwise seasonal increase of this virus.”.
The G11.17 strain has been circulating for several decades, the network reports, and last year parts of Europe experienced a sudden rise. Norovirus cases in the U.S. had previously been dominated by the G11.4 strain. Experts also said that more studies were needed on the new variant. “What we are seeing has happened before for noroviruses. Noroviruses are very diverse,” Marion Koopmans, head of the Erasmus MC Department of Viroscience, told CBS.
The virus causes 465,000 emergency department visits, which are mostly young children. Unfortunately, there is no quick fix or medication to treat norovirus so experts say rehydration and plenty of rest is key if you do catch it. The good news is there are basic hygiene steps you can take to prevent your chances of catching it this winter.
Health officials recommend washing your hands with soap and water regularly for at least 20 seconds, particularly after using the toilet or changing diapers, before eating, preparing or handling food, or before giving yourself or someone else in your care medicine.
