Chikungunya Outbreak Alert in Seychelles

The Centers for Disease Control and Prevention (CDC) has issued a Level 2 warning regarding a chikungunya outbreak in Seychelles, emphasizing the need for travelers to practice enhanced precautions while visiting the region.

Chikungunya is a viral disease caused by the chikungunya virus and is primarily transmitted to humans through bites from infected mosquitoes. This virus is prevalent in various regions, including parts of Africa, the Americas, Asia, Europe, and islands in the Caribbean, as well as within the Indian and Pacific Oceans.

The onset of chikungunya symptoms typically occurs between three to seven days following a bite from an infected mosquito. The most common symptoms include fever and significant joint pain. Additionally, affected individuals may experience headaches, muscle aches, rash, and swelling in the joints. Although many individuals recover within a week, a portion may experience persistent joint pain that can last for months or even years following the initial illness.

Individuals who are considered at a higher risk for more severe disease outcomes include newborns infected at or around the time of birth, older adults aged 65 and above, and those with preexisting medical conditions like diabetes and heart disease. Fortunately, fatalities resulting from chikungunya are uncommon.

As there is no specific treatment available for chikungunya, preventive measures are critical. Travelers to Seychelles are advised to take the following precautions:

• Minimize exposure to mosquito bites: Use insect repellents, wear long-sleeved clothing and long pants, and stay in accommodations that offer air conditioning or have proper screening on windows and doors to deter mosquitoes.

• A vaccination recommendation is made for travelers going to areas where chikungunya outbreaks are reported. Travelers, particularly pregnant women close to their due date, should reconsider travel to affected regions. Infected mothers can transmit the virus to their newborns during or before delivery, which may result in serious health issues for the infants.

• While vaccination is generally recommended, pregnant individuals should defer vaccination until after childbirth unless the risk of exposure to the virus is significantly high. In such cases, it is crucial for pregnant travelers to discuss with their healthcare providers the potential risks associated with chikungunya infection for both themselves and their babies, alongside the benefits and risks of vaccination.

If you experience fever, joint pain, headaches, muscle pain, joint swelling, or rashes while traveling or after your trips, seek medical attention promptly.

For healthcare providers, it is advised to:

• Familiarize themselves with the information about chikungunya vaccination options.
• Discuss the potential benefits and risks of vaccination with travelers based on their age, underlying health issues, travel destination, duration of the trip, and planned activities.

Key informative resources are available through the CDC, including detailed guidelines for travelers visiting Seychelles, further details on chickungunya and vaccines, and recommendations on how to avoid mosquito bites.

For additional information, healthcare providers can refer to the CDC Yellow Book, which contains extensive details on chikungunya and recommendations specifically tailored for international travel.

The CDC reaffirms the importance of awareness regarding this chikungunya outbreak in Seychelles and encourages all travelers to stay informed and well-prepared.
