FAQ
Chikungunya is a mosquito-borne virus primarily transmitted to humans through the bite of infected Aedes mosquitoes, such as Aedes albopictus. The virus is most common in tropical and subtropical regions but has appeared locally in New York recently.
The recent case was confirmed in Nassau County on Long Island, New York. The individual began experiencing symptoms in August 2025 and had not traveled outside the area, indicating local mosquito transmission.
Symptoms usually appear within 3 to 7 days after a mosquito bite and include fever, severe joint pain, headache, muscle pain, joint swelling, rash, nausea, and fatigue. Most recover within a week, but newborns, older adults, and those with underlying conditions are at higher risk for severe illness.
There is no specific antiviral treatment for chikungunya; care focuses on managing symptoms like fever and joint pain. A vaccine is available for travelers to prevent the disease, but it is not broadly available for the general population.
People are advised to use EPA-registered insect repellents, wear long sleeves and pants, reduce standing water around homes to eliminate mosquito breeding sites, and repair window and door screens to prevent mosquito entry.
