Overview
- Wastewater surveillance now shows high rotavirus levels in Davis, Marin, Redwood City, San Jose and Fremont, with moderate readings in San Francisco, Sunnyvale and Novato.
- The same network also reports notable detections in Texas, including near Amarillo, the Woodlands, Dallas–Fort Worth, Wichita Falls and Gainesville.
- Lab tracking found Southern U.S. cases rose in recent weeks, which fits the virus’s usual January to June season.
- Infants and toddlers face the greatest risk, with vomiting and severe watery diarrhea that can cause dangerous dehydration and hospital stays.
- The CDC lists vaccination as the best protection, yet its January shift to parent‑doctor decision-making drew AAP warnings that the move could weaken uptake.
