Chikungunya Outbreak in Seychelles Triggers Global Travel Warning

A surge in cases of the chikungunya virus has prompted health authorities to issue a travel warning for the Seychelles, a popular tourist destination known for its stunning beaches and vibrant wildlife. The Centre for Disease Control (CDC) in the United States has classified the situation as a level 2 travel warning, advising travelers to take appropriate precautions. Local health officials report that the virus is becoming increasingly prevalent in the archipelago, with the European Centre for Disease Control (ECDC) predicting a rise in cases, including several imported infections in EU countries linked to travel to the Seychelles since December 2025.

Understanding Chikungunya

Chikungunya is a mosquito-borne virus primarily transmitted through bites from Aedes mosquitoes, which are active during the day, particularly at dawn and dusk. The virus is prevalent in over 100 countries across Africa, Asia, the Americas, the Caribbean, and Pacific islands. While it is less common in Europe, rising temperatures have led to the emergence of the virus in southern regions, specifically Italy and France.

Symptoms typically manifest four to eight days after being bitten, starting with a high fever and severe joint pain. Additional symptoms may include a rash, headache, fatigue, nausea, and muscle pain. Although serious complications are rare, certain groups, including infants, the elderly, and individuals with pre-existing health conditions, are at higher risk. Most people recover within a week, but some may experience lingering joint pain and arthritis for several months or even years post-infection. Other potential complications can affect the eyes, neurological system, heart, and gastrointestinal tract.

Preventing Infection

Currently, there is no specific treatment for chikungunya. The most effective method of prevention is to minimize the risk of mosquito bites. Those planning to travel to areas affected by chikungunya are advised to use insect repellent containing DEET and wear light protective clothing to cover exposed skin.

In the UK, two chikungunya vaccines have recently received approval for use in certain travelers. Eligibility for vaccination includes those traveling to regions experiencing outbreaks, frequent travelers to areas with recent chikungunya transmission, and laboratory personnel working with the virus. Health professionals recommend discussing vaccination options and other protective measures before traveling to areas with active outbreaks.

As the situation in the Seychelles continues to develop, travelers are encouraged to stay informed and take necessary precautions to protect their health. For more information on preventing chikungunya while traveling, visit the National Travel Health Network Centre.
