Austin Leads Texas's Travel-Related Dengue Cases Again

Now in its third decade of serving travelers in Central Texas, Austin–Bergstrom International Airport welcomed over two million visitors last month, many of whom arrived from overseas.

Unfortunately, this year, eight visitors to Travis County, and Austin, Texas, contracted the Dengue virus while traveling abroad.

Last year, Travis County reported 18 travel-related cases of Dengue, the most in Texas.

According to the Texas Department of State Health Services' (DSHS) arbovirus weekly report #36, there have been 31 travel-related Dengue cases reported in Texas this year.

This news is relatively positive compared to 2024, when 143 imported Dengue cases and one related fatality occurred across 23 Texas counties.

Texas is not alone in reporting fewer Dengue cases in 2025.

Throughout the United States, 3,045 cases of mosquito-transmitted Dengue have been confirmed this year.

In 2024, 53 U.S. jurisdictions reported 9,391 Dengue cases.

Only a few states, such as Florida, reported locally acquired Dengue cases last year.

And in the Region of the Americas, as of epidemiological week 34, a total of 3,740,133 suspected cases of Dengue were reported in 2025. This data represents a 68% decrease compared to the same period in 2024.

To enhance disease detection, the U.S. Centers for Disease Control and Prevention (CDC) advised clinicians in July 2025 to consider Dengue in patients with fever who live in or have recently traveled to areas with a risk of Dengue.

Furthermore, to alert international travelers to this health risk, the CDC reissued a Global Travel Health Notice on August 21, 2025, regarding Dengue outbreaks in the Americas, Africa/Middle East, and Asia/Pacific regions, in countries such as India, Singapore, Thailand, the Philippines, Malaysia, and Myanmar. 

From a disease prevention perspective, the CDC says mitigating mosquito bites is the best option, as access to Dengue vaccines in the USA is currently limited to children in Puerto Rico.
