Wisconsin has been grappling with a surge in norovirus outbreaks, setting a new record with 100 outbreaks in December alone, compared to 30 in November.
Norovirus, known for causing vomiting and diarrhea, is highly contagious and typically spreads through contaminated food or surfaces.
The outbreaks are more common from November through February, but this year, health experts believe a new strain of the virus is contributing to the spike in cases. This strain, which has fewer people with immunity, is thought to be spreading faster than the previous dominant strain that had circulated for the past decade.
While cases in Wisconsin’s long-term care facilities and campuses like the University of Wisconsin-Eau Claire have been notable, health officials report that symptoms have been more severe than usual.
Public health experts emphasize proper handwashing over hand sanitizers and recommend that people stay home for at least 48 hours after symptoms resolve to prevent further spread.
Tracking the virus has proven difficult as it often goes unreported, making it harder for authorities to gauge its full impact.
