Dengue Cases in Argentina: A Declining Trend
The Pan American Health Organization (PAHO) has released a recent report highlighting a significant decrease in dengue cases in Argentina. As of November 4, 2025, the country has reported a total of 17,689 dengue cases and 17 related fatalities this year, a substantial drop from the over 580,000 cases confirmed in 2024. This positive development comes as a relief to health authorities and travelers alike, especially considering the potential risks associated with dengue fever.
The focus of PAHO's efforts is on the Southern Cone subregion, which includes Argentina, Brazil, Chile, Paraguay, and Uruguay. In Argentina's Central and Northwest regions, three dengue serotypes—DENV-1, DENV-2, and DENV-3—have been detected over the past year. This information is crucial for travelers and residents, as it highlights the ongoing risk in specific areas.
The U.S. Centers for Disease Control and Prevention (CDC) emphasizes that anyone living in or traveling to regions with a dengue risk is susceptible to infection. Despite this, Argentina is currently not included in the CDC's Global Health Notice, indicating that the country has successfully managed the dengue outbreak. However, it's essential for travelers to stay informed and take necessary precautions when visiting areas with a higher risk of dengue transmission.
This decline in dengue cases is a testament to the effective measures implemented by health authorities in Argentina. As the country continues to monitor and manage the situation, travelers can feel more confident about their visits, knowing that the risk of dengue fever is significantly reduced compared to previous years.
