Norovirus Outbreaks Surge Nationwide, Illinois Reports Record Winter Spike

The highly contagious stomach virus has seen a dramatic rise in outbreaks this season, with Illinois experiencing its highest numbers in years and health officials emphasizing prevention measures.

• Illinois reported at least 103 norovirus outbreaks in November and December 2024, a significant increase compared to 22 outbreaks in the same period in 2023.
• The CDC recorded a 36% rise in national norovirus outbreaks this winter compared to the previous year, with cases peaking earlier than usual.
• Norovirus spreads easily through contaminated food, surfaces, and close contact, with symptoms including vomiting, diarrhea, and dehydration typically lasting 1-3 days.
• Health experts stress frequent hand-washing with soap and water as the most effective prevention method, as hand sanitizers are less effective against the virus.
• Officials recommend isolating infected individuals, thorough cleaning of shared spaces, and avoiding food preparation if symptomatic to curb the spread.
