A mosquito-borne virus that causes high fever and joint pain is believed to have infected more than 35,000 people across the Caribbean, according to news reports.
Most of the 4,000 confirmed cases of the chikungunya virus are in the French islands of Martinique, Guadeloupe and St. Martin. The painful illness was first detected in December in St. Martin.
It is rarely fatal and most patients rebound within a week, but some people experience joint pain for months to years. There is no vaccine and it is spread by the same pervasive Aedes aegypti mosquito that transmits dengue fever.
In late April, St. Vincent & the Grenadines and Antigua & Barbuda became the latest Caribbean countries to report confirmed cases.
