Travel Alert: Chikungunya in Saint Martin (Caribbean)
On December 12, 2013, the World Health Organization (WHO) reported 10 cases of chikungunya that have been identified in people who live on the French side of St. Martin in the Caribbean. Laboratory testing is being carried out to confirm other possible cases. This is the first time that local transmission of chikungunya has been reported in the Americas. Local transmission means that mosquitoes in the area have been infected with chikungunya and are spreading it to people.
Chikungunya is an illness caused by a virus that spreads through mosquito bites. The most common symptomsof chikungunya are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash.
Travelers who go to St. Martin in the Caribbean are at risk of getting chikungunya. In addition, travelers to Africa, Asia, and islands in the Indian Ocean and Western Pacific also are at risk, as the virus is spread in many of these areas. The mosquito that carries chikungunya virus can bite during the day and night, both indoors and outdoors, and often lives around buildings in urban areas.
There is currently no vaccine or medicine to prevent chikungunya. Travelers can protect themselves by preventing mosquito bites.
