The Ministry of Health confirmed on April 17 the fifth positive case of chikungunya fever in the country for 2026, based on results from the laboratory at the Costa Rican Institute for Research and Teaching in Nutrition and Health (INCIENSA).
This development is important as it highlights ongoing concerns about imported cases of mosquito-borne diseases and underscores public health efforts to monitor and control outbreaks.
According to health authorities, the latest case involves a 37-year-old woman residing in Tibás who recently traveled to Nicaragua. The epidemiological investigation determined that she entered Costa Rica during the incubation period of the virus, leading officials to classify this as an imported case.
Earlier this year, four other cases were confirmed: two in Esparza canton, one in Guanacaste, and one in Heredia. Chikungunya symptoms typically include high fever (over 39°C), joint pain and swelling, headache, nausea, and general discomfort.
The Ministry stated that epidemiological surveillance remains active nationwide. Authorities continue coordinating actions aimed at controlling the mosquito vector responsible for transmission to protect public health and prevent further spread.
In its statement, “El Ministerio de Salud reafirma su compromiso con la prevención y la atención oportuna de las enfermedades e insta a la ciudadanía a mantenerse informada únicamente por medio de los canales oficiales.” This translates as: “The Ministry of Health reaffirms its commitment to prevention and timely care for diseases and urges citizens to stay informed only through official channels.”
Health officials recommend that residents remain vigilant regarding disease prevention measures while following updates provided by official sources.
