U.S. Health officials have issued a travel advisory for parts of Bolivia following an outbreak of chikungunya, a mosquito-borne virus that can cause fever and severe joint pain. The Centers for Disease Control and Prevention (CDC) issued a Level 2 Travel Health Notice on February 11, 2026, advising travelers to practice enhanced precautions in the Santa Cruz and Cochabamba departments. This alert comes as cases of the virus are rising, prompting concerns for those planning to visit the South American nation.
Chikungunya, while rarely fatal, can cause debilitating symptoms. The virus is transmitted through the bite of infected mosquitoes, and there is currently no specific treatment available. Prevention, is paramount. The CDC’s Level 2 advisory doesn’t recommend avoiding travel to Bolivia, but it does emphasize the importance of taking extra steps to protect against mosquito bites.
Understanding the Current Outbreak
The outbreak is currently concentrated in the Santa Cruz and Cochabamba departments of Bolivia. According to the CDC, a Level 2 “Practice Enhanced Precautions” notice is issued when there is an elevated health risk, such as an active disease outbreak. This means travelers should be particularly vigilant about protecting themselves from mosquito exposure. The CDC is continuing to monitor the situation and will update its guidance as needed.
Symptoms of chikungunya typically appear three to seven days after being bitten by an infected mosquito. These commonly include fever and joint pain, but can similarly manifest as headache, muscle pain, joint swelling, and rash. While most individuals recover within approximately a week, some patients experience persistent joint pain for months, or even years, following the initial infection. Certain populations—newborns, adults 65 and older, and individuals with underlying medical conditions like diabetes or heart disease—are at higher risk of severe illness.
Protecting Yourself from Chikungunya
The most effective way to avoid chikungunya is to prevent mosquito bites. The CDC recommends several preventative measures, including using insect repellent containing DEET, picaridin, or oil of lemon eucalyptus. Wearing long-sleeved shirts and pants can also help minimize exposed skin. Travelers are also advised to stay in accommodations with air conditioning or screens on windows and doors to keep mosquitoes out.
While there is no specific medication to treat chikungunya, supportive care can help manage symptoms. This includes rest, fluids, and pain relievers. The CDC notes that vaccination against chikungunya is recommended for those traveling to areas with active outbreaks, though availability may vary. It’s crucial to consult with a healthcare provider before traveling to discuss vaccination options and other preventative measures.
What the CDC is Saying
The CDC emphasizes the importance of proactive measures. According to the agency, “You can protect yourself by preventing mosquito bites, which includes using insect repellent, wearing long-sleeved shirts and pants, and staying in places with air conditioning or that have screens on the windows and doors. Vaccination is recommended for travelers who are visiting an area with a chikungunya outbreak.”
The CDC also provides specific guidance for pregnant travelers, advising them to reconsider nonessential travel to affected areas, particularly close to delivery, due to the risk of transmission to the baby around the time of birth.
Looking Ahead
The CDC continues to monitor the chikungunya outbreak in Bolivia and will provide updates to its travel health notices as the situation evolves. Travelers planning trips to the affected areas are encouraged to check the CDC website for the latest information and recommendations before their departure. Seeking medical attention if symptoms develop during or after travel is also crucial.
This outbreak underscores the ongoing threat of mosquito-borne illnesses and the importance of public health vigilance. As global travel resumes, staying informed about potential health risks and taking appropriate preventative measures is essential for a safe and healthy journey.
