Quick summary: The Centers for Disease Control and Prevention has issued a Level 2 Travel Health Notice for Guanacaste Province, Costa Rica, after a chikungunya outbreak was linked to Playa Langosta. Travelers are advised to take enhanced precautions to avoid mosquito bites; pregnant women should reconsider travel to the affected area.
The advisory was prompted after Costa Rica’s Ministry of Health reported four confirmed cases and 17 probable cases connected to a cluster in Playa Langosta. The counts — 4 confirmed and 17 probable — come from the Costa Rica Ministry of Health and are being tracked alongside CDC guidance on prevention and clinical risk.
Chikungunya outbreak: where cases are and counts
Most cases tied to the investigation have been reported in and around Playa Langosta, a popular beach area in Guanacaste Province. Officials say the cluster includes both residents and visitors; health authorities are continuing contact tracing, testing and case confirmation work.
The Costa Rica Ministry of Health provided the specific counts: four confirmed infections and 17 probable cases. Local and national health teams are coordinating with international guidance from the CDC to monitor travel-related risk and to advise clinicians caring for suspected patients.
Symptoms and long-term risk
Chikungunya is a mosquito-borne viral illness that most commonly causes sudden onset fever and severe joint pain. Typical symptoms appear three to seven days after an infectious mosquito bite and often include headache, muscle pain, joint swelling and a rash.
Most people recover within days to a week, but the CDC notes that some patients can experience prolonged joint pain lasting months to years after the initial infection. There is no specific antiviral treatment; medical care is supportive and emphasizes pain relief and hydration.
Prevention and CDC travel advice
The CDC’s Level 2 Travel Health Notice recommends travelers take enhanced precautions to avoid mosquito bites. Key, explicit measures listed by the CDC include: “using insect repellent,” “wearing long-sleeved shirts and pants,” and “staying in accommodations with air conditioning or window screens.”
Because chikungunya infection near the time of delivery may pose risks to newborns, the CDC also advises that pregnant women reconsider travel to areas with active transmission, particularly late in pregnancy. Travelers should consult their health care provider before travel if they are pregnant or have underlying health concerns.
Local response and control measures
Local health teams in Guanacaste have mobilized quickly to reduce mosquito populations and lower transmission risk. Authorities report fumigating approximately 5,000 homes and conducting targeted source-elimination campaigns to remove standing water and other mosquito breeding habitats.
Public health staff are performing community outreach to educate residents and visitors on how to identify and eliminate breeding sites, and are conducting door-to-door vector-control work in neighborhoods near reported cases. These measures follow standard outbreak control practices used for Aedes-transmitted diseases such as chikungunya.
Practical steps for travelers
If you are planning travel to Guanacaste or are already in the region, follow CDC guidance closely. Use an EPA-registered insect repellent on exposed skin and clothing, wear long sleeves and long pants when mosquitoes are active, and sleep or stay in places with air conditioning or intact window screens.
Pack symptom-relief basics such as acetaminophen for fever and pain, and seek medical care if you develop fever with severe joint pain, rash, headache or other concerning symptoms during or after travel. Inform clinicians about recent travel to areas with reported cases so appropriate testing and supportive care can be provided.
What health officials are watching next
Health teams are monitoring for new cases and evaluating mosquito activity across the province. Counts reported by Costa Rica’s Ministry of Health remain under active investigation and could change as laboratory testing and case reviews continue.
Authorities will continue fumigation, source elimination and public education until transmission is controlled. Travelers should monitor official health channels and follow any local advisories while public health actions continue.
