- A rare, locally acquired case of chikungunya, a mosquito-borne virus, has been confirmed in the New York City suburbs, marking the first mainland US transmission in a decade and the first ever in New York.
- The Long Island patient developed symptoms in August following travel within the country, with the infection believed to be from a mosquito bite, though the virus has not been detected in local mosquito populations.
- Chikungunya typically causes mild symptoms like fever and joint pain, but can lead to debilitating, long-lasting joint pain in rare cases, with severe outcomes mostly affecting babies or elderly individuals.
- There is no specific treatment for chikungunya, but symptoms can be managed; two vaccines are approved in some regions, primarily for travellers.
