Record Dengue Surge in the United States in 2024 Fueled by Travel-Associated Cases

CDC data show a record 3,798 dengue cases in the United States and DC in 2024, up 359% from the 2010–2023 average, with travel-associated cases (97.2%) far exceeding locally acquired ones (2.8%). The Caribbean, Mexico, and Cuba were major exposure regions; Florida, California, and Texas reported local transmission in multiple counties. The median patient age was 49; 57.5% identified as Hispanic/Latino, and 36.1% were hospitalized, with six deaths (0.2%). DENV-3 was the most common serotype among those tested. The findings call for stronger prevention, vector control, and traveler-focused messaging, while vaccines are not yet available for short-term travelers; protective measures include EPA-approved repellents, protective clothing, screens, and reducing standing water.

Five Summer Moves to Deter Mosquito Bites, According to Experts

Experts say you can’t completely avoid mosquitos, but you can cut bites with five summer strategies: remove standing water around your home to curb breeding, use proven repellents (such as DEET, picaridin, or IR3535), wear protective clothing, keep doors and windows sealed with screens, and maintain landscaping to reduce mosquito habitats. The piece notes mosquitos can spread diseases like dengue and West Nile virus, and that climate change is expanding mosquito ranges and seasons in the U.S.

Kissing bugs and the hidden threat of Chagas disease

Kissing bugs in central and northern South America bite at night and can transmit the Trypanosoma cruzi parasite via their feces; this infection causes Chagas disease, which damages the heart and digestive muscles and can be fatal if untreated. The WHO estimates about 8 million people are infected worldwide with around 10,000 deaths annually, a history tied to Darwin’s South American travels.

Oropouche and Sloth Viruses: Emerging Threats in the Americas and UK

Guyana is the only Caribbean country with a confirmed case of Oropouche fever, a viral disease spreading across the Americas, primarily transmitted by midges, with no current vaccine or specific treatment. PAHO emphasizes the need for surveillance, vector control, and public health measures to prevent further spread, especially as climate change and urbanization increase midge populations.

Massachusetts Reports First EEE-Positive Mosquito of 2025 Season

Massachusetts has confirmed its second case of Eastern Equine Encephalitis (EEE) in mosquitoes this year, with no human or animal cases reported yet. The infected mosquitoes were found in Bridgewater and Belchertown, prompting health officials to advise precautions such as using insect repellent and eliminating standing water to reduce mosquito bites. EEE is a deadly virus with a high fatality rate and potential for severe neurological damage, but most human cases occur in late summer and early fall.
