The Pan American Health Organization (PAHO) recently reported very positive news regarding the multi-year outbreak of dengue fever in the Region of the Americas.
On July 10, 2025, the PAHO reported In the epidemiological week #25 of 2025, a total of 3,349,004 suspected cases of dengue were reported this year. This data represents a significant 70% decrease compared to the same period in 2024 and an 11% decrease compared to the average of the last five years.
Additionally, a total of 1,600 fatalities have been recorded, resulting in a case fatality rate of 0.048%.
While the majority of dengue cases have been reported in Brazil, Mexico’s dengue outbreak remains a concern in 2025.
Mexico has reported 49,085 cases and 2,352 related fatalities this year.
From a sub-type perspective, Brazil, Costa Rica, El Salvador, Mexico and Panama report the simultaneous circulation of DENV1, DENV-2, DENV-3, and DENV-4.
This PAHO data indicates the need for international travelers to obtain dengue vaccinations may diminish during the summer of 2025. In the United States, only Puerto Rico offers dengue vaccinations.
