Chikungunya in the CaribbeanUpdated January 20, 2015
Updated: January 13, 2015
What is the current situation?
In December 2013, the World Health Organization (WHO) reported local transmission of chikungunya in Saint Martin. Local transmission means that mosquitoes in the area have been infected with chikungunya and are spreading it to people. This is the first time that local transmission of chikungunya has been reported in the Americas.
Local transmission of chikungunya is now being reported in other countries in the Caribbean. As of January 9, 2015, the following Caribbean countries have reported cases of chikungunya:
- British Virgin Islands
- Cayman Islands
- Dominican Republic
- Puerto Rico
- Saint Barthelemy
- Saint Kitts
- Saint Lucia
- Saint Martin (French)
- Saint Vincent and the Grenadines
- Sint Maarten (Dutch)
- Trinidad and Tobago
- Turks and Caicos Islands
- US Virgin Islands
CDC recommends that travelers to the Caribbean protect themselves from mosquito bites. Some travelers may be more likely to get chikungunya, have severe disease, or be at higher risk for other reasons. CDC advises travelers in high-risk groups to discuss their travel plans with their health care provider. These groups include the following:
- People who have arthritis
- People with serious underlying medical conditions (such as high blood pressure, heart disease, or diabetes)
- People older than 65
- Women who are late in their pregnancies, because of the risk to babies born at the time their mother is sick
- Long-term travelers, including missionaries and humanitarian aid workers and people visiting friends and relatives
- People who might have difficulty avoiding mosquito bites, such as those planning to spend a lot of time outdoors or staying in rooms without window screens or air conditioning.
What is chikungunya?
Chikungunya is an illness caused by a virus that spreads through mosquito bites. The most common symptoms of chikungunya are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Chikungunya disease rarely results in death, but the symptoms can be severe and disabling. Most people who get sick feel better within a week. In some people, the joint pain may last for months or years.
Who is at risk?
Travelers who go to these islands in the Caribbean are at risk of getting chikungunya. In addition, travelers to Africa, Asia, and islands in the Indian Ocean and Western Pacific are also at risk, as the virus is present 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.
What can travelers do to prevent chikungunya?
There is currently no vaccine or medicine to prevent chikungunya. The only way to prevent chikungunya is to prevent mosquito bites. Preventing bites can be difficult, but it is important as you can get sick after just one bite. Follow these steps to reduce the chances that you will be bitten by mosquitoes during your trip.
