Cases of chikungunya virus, a painful, mosquito-borne disease that has spread rapidly through the Caribbean in recent months, spiked higher in New York and New Jersey in the past week, according to new federal data.
The number of cases in New Jersey more than doubled to 25, while New York has recorded 44 cases, the highest number outside Florida, where the disease first established a toehold in the United States, according to data released late Tuesday by the Centers for Disease Control and Prevention. Officials in New Jersey and New York do not believe any of the cases originated in their state. Symptoms, which develop three to seven days after being bitten by an infected mosquito, include high fever, headache, muscle pain, back pain and rash. In rare cases it is fatal.
