Argentina’s dengue season began slowly, with 1,443 confirmed cases as of March 10, 2025. Most cases were locally transmitted, primarily in the Central and Northwest regions. Health authorities are implementing strategic plans and spatial analyses to combat future outbreaks, while the U.S. CDC issues travel advisories for at-risk visitors.

Argentina’s dengue season for 2024/2025 commenced during week 31 of 2024, with the Ministry of Health confirming a total of 1,443 cases as of March 10, 2025. Notably, 96.9% of these cases were locally transmitted, reflecting a high level of mosquito transmission within the country.

The Central and Northwest regions of Argentina have reported the highest incidence of dengue cases, with totals of 816 and 237 respectively. There were also 45 cases associated with travel to countries such as Brazil, Cuba, Mexico, and others. This situation arises amidst significant international travel to Argentina, particularly to Buenos Aires.

In the previous year, Argentina recorded approximately 581,000 dengue cases alongside 400 fatalities related to the virus. As part of its response to combat dengue, Health Minister Mario Lugones convened a meeting on March 11, 2025, to review ongoing actions and develop strategies for enhanced response capabilities against future outbreaks.

Additionally, plans for a new national dynamic map are underway, which will compile geographic, demographic, and climatic data such as rainfall and temperature. This initiative aims to facilitate timely preventive measures and predict potential dengue outbreaks.

In light of ongoing dengue transmission, the U.S. Centers for Disease Control and Prevention (CDC) has reiterated its Travel Health Advisory for regions experiencing dengue in the Americas. They advise travelers to endemic areas to avoid mosquito bites, particularly due to the unavailability of dengue vaccines in the United States.

The dengue season in Argentina has been marked by significant local transmission, with a majority of cases reported in the Central and Northwest regions. The health authorities are proactively addressing the situation through strategic planning and the development of a dynamic national map. Travelers are advised to exercise caution, following CDC guidance, amidst the current dengue epidemic.
