Severe Rotavirus Spike Threatens Florida Infants

Florida parents are being warned that rotavirus and other stomach viruses are rising fast, with babies and toddlers facing the highest risk of dehydration and hospital care. (patch.com) Rotavirus is a highly contagious virus that usually starts about two days after exposure and can bring vomiting, watery diarrhea, fever and stomach pain for three to eight days. Infants and young children get the sickest because fluid loss can become dangerous quickly. (cdc.gov) The Centers for Disease Control and Prevention tracks rotavirus through its National Respiratory and Enteric Virus Surveillance System, which updates weekly from participating labs. National reporting showed a steep rise beginning in January 2026, with 7.3% of tests positive in early April, higher than the 2025 seasonal peak. (cdc.gov; beckershospitalreview.com) Doctors worry most about children from about 3 months to 3 years old, especially those who are unvaccinated. The Centers for Disease Control and Prevention says the most severe rotavirus disease occurs primarily in that age group. (cdc.gov) This virus spreads the way many stomach bugs do: tiny particles from contaminated hands, diapers, toys, food or surfaces get into a child’s mouth. That makes day care centers and homes with multiple young children common places for it to move fast. (cdc.gov; healthychildren.org) The main danger is dehydration, not just diarrhea. The Centers for Disease Control and Prevention lists decreased urination, dry mouth, few or no tears, unusual sleepiness and fussiness among the warning signs that should push parents to call a doctor promptly. (cdc.gov) There is no specific drug that cures rotavirus, so treatment is mostly fluids and monitoring. Some children recover at home with oral rehydration, while others need intravenous fluids in an emergency department or hospital. (cdc.gov; msdmanuals.com) Vaccination changed the picture in the United States after 2006, cutting severe illness and hospitalizations sharply. The Centers for Disease Control and Prevention says the vaccine provides 85% to 98% protection against severe rotavirus illness and hospitalization in an infant’s first year. (cdc.gov) But coverage has slipped. U.S. rotavirus vaccination rates fell from 77% of children fully vaccinated by 8 months in 2018 to 74% in 2024, according to epidemiologist Annette Regan in The Conversation, citing federal data. (theconversation.com) The vaccine is given by mouth, not by shot, and the schedule starts early: one brand is given at 2, 4 and 6 months, and the other at 2 and 4 months. The first dose must be given before 15 weeks of age, and all doses must be finished before 8 months. (cdc.gov; cdc.gov) For Florida families, the immediate question is simpler than the surveillance charts: whether a vomiting child is still making wet diapers, drinking fluids and staying alert. If those signs fade, doctors say the problem can turn serious in hours, not days. (patch.com; cdc.gov)
