Tampa Woman’s Dengue Death Raises Alarm Over Local Transmission

An 80-year-old Tampa woman, Gay Small, died within a week after contracting dengue fever—a locally transmitted outbreak that officials say could mark the first fatal dengue case in Tampa Bay in nearly a century if confirmed. The region has seen a surge of dengue this summer, with Hillsborough County reporting 59 locally acquired infections and Tampa General treating about 20 cases; doctors caution that dengue can be severe, especially in older adults, and that the disease is spreading locally rather than just affecting travelers. Small’s family, who are familiar with the disease through her late husband’s vaccine work, shared her story to raise awareness as an autopsy is planned to determine the exact cause of death.

Breakbone Fever Reaches Florida: Local Dengue Transmission Returns After 15 Years

Florida is seeing local transmission of dengue fever for the first time in about 15 years, with 10 locally acquired cases this year (eight in Hillsborough County and two in Pinellas County). Dengue is mosquito-borne and not native to Florida; most cases come from travelers who bring the virus, after which local mosquitoes can spread it. Symptoms can include fever, rash and body aches; treatment is supportive. The CDC recommends protecting against bites with long sleeves/pants and insect repellents containing DEET, picaridin, lemon eucalyptus, or para-menthane-diol to prevent infection.

East Tennessee records a rare La Crosse virus neuroinvasive case

The CDC confirms a human case of La Crosse virus in Claiborne County, East Tennessee—the first and only Tennessee infection in 2026 and one of only four U.S. cases this year—transmitted by mosquitoes and capable of neuroinvasive disease such as encephalitis or meningitis. The virus is native to the Appalachian forest ecosystem; officials urge residents to drain standing water, use EPA-approved repellents, keep screens intact, and wear long sleeves and pants during peak mosquito activity as cases are monitored.

Embassy Warns of Local Chikungunya Outbreak at Playa Langosta, Costa Rica

The U.S. Embassy has issued a health alert for Playa Langosta in Guanacaste, Costa Rica, due to local chikungunya transmission; travelers should watch for fever, joint pain, headaches, and nausea, and take bite-prevention steps since there is no vaccine.

Costa Rica remains broadly safe for tourists with a Level 2 State Department advisory, so review current safety advisories before traveling.

NSW Health flags probable Japanese encephalitis case as climate-driven spread grows

New South Wales Health says a probable Japanese encephalitis case is under investigation in a man in his 60s who was likely exposed in the Riverina region; JE has been detected in chickens used for early warning. While JE is usually mild, encephalitis can occur and has a case-fatality rate up to about 30%. Climate change is linked to the outbreak’s spread, and protection includes avoiding bites, using EPA-registered repellents, permethrin-treated clothing, and vaccines are available (free in high‑risk NSW areas for residents).

Colombia faces yellow fever surge as death toll surpasses 70

Colombia is grappling with a mosquito-borne yellow fever outbreak that has killed more than 70 people since 2024. The government declared a national health emergency last year; from 2024 to January 2026 there were 161 confirmed cases and 73 deaths, including 13 cases and 10 deaths in 2026. Yellow fever symptoms resemble flu—fever, headache and nausea—though severe cases can cause multi-organ failure and internal bleeding; about 15% of patients develop severe illness and roughly half of those die, according to the WHO. The outbreak is being monitored as part of global disease surveillance.
