U.S. Norovirus Cases Rise as 20-Second Handwashing Urged Before Summer Gatherings

Summary
Wastewater data show norovirus levels are high across the U.S. heading into summer, signaling a nationwide uptick rather than an isolated outbreak.
Warmer-weather gatherings—from picnics to weddings—are seen as a likely driver because the virus spreads easily through sick people, contaminated food or drinks, and touched surfaces.
Up to 3 days of sudden vomiting and diarrhea can follow infection, with dehydration the main medical risk; treatment is largely limited to fluids, and severe cases may need IV rehydration.
Soap-and-water handwashing for at least 20 seconds remains the key prevention step because hand sanitizer does not reliably kill norovirus; avoiding people who are actively vomiting also helps.
Doctors say the virus circulates year-round and current levels are still below typical winter peaks, with activity expected to ease as summer progresses.
