Severe Stomach Virus Rising Among Florida Kids

Florida parents are being warned to watch for severe vomiting and watery diarrhea as rotavirus activity rises and young children face the highest risk of dehydration. (cdc.gov) Rotavirus commonly hits infants and young children hardest, and symptoms usually begin about two days after exposure and can last three to eight days, according to the Centers for Disease Control and Prevention. The virus spreads easily in families, hospitals and child care centers through contaminated hands, surfaces and stool. (cdc.gov) National surveillance shows rotavirus detections climbing since January 2026, with early-April test positivity above the same period last year. NBC 6 South Florida, citing CDC data, reported April 15 that doctors were concerned the higher activity could bring more severe illness and hospitalizations. (usatoday.com, nbcmiami.com) The danger for babies and toddlers is not the name of the virus so much as the fluid loss it causes. The CDC says dehydration can show up as decreased urination, a dry mouth, few or no tears, unusual sleepiness or fussiness, and it can send children to the hospital. (cdc.gov) Florida’s public health system points parents to the same basic protection: vaccination in infancy. Florida HealthFinder, which republishes the CDC vaccine guidance, says babies should receive a two- or three-dose oral series, with the first dose given before 15 weeks of age and the last by 8 months. (quality.healthfinder.fl.gov) The vaccine does not block every future infection, but the CDC says vaccinated children are less likely to get seriously ill from rotavirus. Before vaccines were introduced, rotavirus was a major U.S. cause of severe diarrhea in young children, with more than 200,000 emergency visits and up to 70,000 hospitalizations a year, NBC News reported, citing the National Foundation for Infectious Diseases. (cdc.gov, nbcmiami.com) Handwashing still matters, but the CDC says hygiene alone is not enough to control rotavirus spread. That is one reason doctors pay close attention when cases rise in places where very young children share bathrooms, toys and changing tables. (cdc.gov) Parents are generally told to call a doctor quickly if a child has ongoing vomiting, fever, or signs of dehydration, especially in infants and toddlers. In Florida, the state health department directs residents to county health departments for local health information and services as the spring rotavirus season continues. (cdc.gov, floridahealth.gov)
