Update to our October dengue coverage: Florida's dengue count keeps climbing. As of October 22, the state had reported 721 cases this year — locally acquired and travel-linked combined — nearly double the 392 logged in September, according to CDC figures reported by HealthDay on October 26. Hillsborough County remains the center of the outbreak, and new cases have also turned up in Orange, Broward and Miami-Dade counties. Nationwide, the CDC reports 2,470 cases in 2026.
Most dengue infections cause no symptoms. When they do, fever with aches, nausea, vomiting or a rash is typical, lasting two to seven days. About 1 in 20 people who get sick develop severe dengue, which can become dangerous within hours. The CDC urges anyone with symptoms who lives in or recently visited a dengue-risk area to see a healthcare provider, and anyone with warning signs — belly pain, vomiting at least three times in 24 hours, or bleeding from the nose or gums — to get emergency care right away.
At home, dump standing water from buckets, tires and containers where mosquitoes breed.
