Cases of norovirus, a highly contagious virus causing gastrointestinal illness, are on the rise in the U.S., according to the Centers for Disease Control and Prevention (CDC). During the week of Dec. 5, over 90 outbreaks were reported, surpassing the previous high of 65 for the same week in earlier years. States like Minnesota have seen outbreaks nearly double their usual numbers.
Norovirus is the leading cause of foodborne illness in the U.S., accounting for 58% of cases annually. It spreads easily through contact with infected individuals, contaminated surfaces, or consuming tainted food and drinks. Symptoms typically include nausea, vomiting, stomach pain, and diarrhea, with some experiencing fever and body aches. Illness often resolves within one to three days but can lead to severe dehydration in infants, the elderly, and those with weakened immune systems.
There is no specific treatment for norovirus, so symptom management is key. The CDC emphasizes staying hydrated and replenishing electrolytes lost through vomiting and diarrhea. To prevent infection, wash hands with soap and water for 20 seconds, as hand sanitizer is less effective against the virus. Properly washing fruits and vegetables and cooking shellfish to 145°F can also reduce risk.
