The Costa Rica Ministry of Health reaffirms its commitment to protecting the health of the population by strengthening dengue surveillance, prevention and control measures throughout the country as cases rise in the country.
According to the latest data reported by the Health Surveillance Directorate, as of epidemiological week 32 of 2026, 3,437 cumulative cases of dengue have been reported, representing a 30% increase compared to the same period in 2025, when 2,405 cases were recorded.
The North Central Region has the highest number of accumulated cases, with 1,050, while the Central Pacific Region has the highest rate, with 240.2 cases per 100,000 inhabitants.
Through the Vector Control Program, the Ministry of Health maintains a permanent intervention that includes actions of epidemiological surveillance, inspection, health education, identification, treatment and elimination of breeding sites, as well as fumigation in the areas that have a greater presence of the Aedes aegypti mosquito, the main transmitter of dengue.
As part of these actions, to date the Vector Control Program teams have visited 396,517 homes, eliminated or treated 2,424,609 breeding sites and fumigated 521,679 houses, contributing to reducing the conditions that favor mosquito reproduction and disease transmission.
These interventions are part of a comprehensive strategy that also requires community participation. Dengue control is a shared responsibility among institutions, families, communities, the private sector, and local governments.
For this reason, the Ministry of Health is calling on the population to maintain and reinforce prevention measures in homes, workplaces and communities, through the periodic review of patios, gardens and lots, as well as the elimination of containers and objects that can accumulate water, including tires, bottles, cans and other disused items.
Dengue fever can manifest with symptoms such as fever, muscle or joint pain, and general malaise. If warning signs appear, such as abdominal pain and vomiting, it is essential to seek medical attention promptly for evaluation and treatment. Likewise, self-medication is not recommended, and a healthcare professional should be consulted if symptoms consistent with dengue develop.
