Understanding the Chikungunya Outbreak in Costa Rica
The recent outbreak of chikungunya in Costa Rica, specifically in the Guanacaste Province, has prompted the U.S. Centers for Disease Control and Prevention (CDC) to issue a Level 2—Practice Enhanced Precautions warning for travelers. As of July 16, 2026, the CDC has advised travelers to take necessary precautions to prevent mosquito bites, which can spread the virus. The outbreak has been reported in Playa Langosta, with 4 confirmed cases and 17 probable cases tied to the mosquito-borne virus.
Chikungunya disease is caused by the chikungunya virus and is spread to humans through mosquito bites. The symptoms of chikungunya usually begin 3–7 days after a bite by an infected mosquito and can include fever, joint pain, headache, muscle pain, joint swelling, or rash. While most people infected with chikungunya virus develop some symptoms, some can have severe joint pain for months to years following acute illness. People at risk for more severe disease include newborns infected around the time of birth, older adults (65 years or older), and people with medical conditions such as diabetes or heart disease.
