The Texas Department of State Health Services (DSHS) has reported the first locally acquired case of dengue virus in 2024 in a resident of Cameron County. The announcement comes amid an active year for dengue virus globally, with 106 travel-associated cases, including one death, already reported in Texas. This figure marks the highest annual case count in the state since 2002.
Health officials have emphasized the importance of precautions against mosquito bites both within Texas and during international travel to regions where the virus is endemic. These areas include the South Pacific, Asia, the Caribbean, South and Central America, and Africa.
Dengue virus is spread by infected mosquitoes. Approximately 25% of those infected show symptoms such as fever, nausea, vomiting, rash, muscle aches, joint pain, bone pain, eye pain, and headaches after an incubation period of three to fourteen days. Most individuals recover completely within two weeks; however, about one in twenty symptomatic patients may develop severe infections that can be fatal if not treated.
DSHS Commissioner Jennifer Shuford stated: “It is important for health care providers to consider a diagnosis of dengue virus and if their patient has symptoms consistent with the disease.” She added that "CDC has many resources for clinical management."
To prevent mosquito-borne diseases like dengue fever, DSHS recommends several protective measures:
- Wear long sleeves and pants to create a barrier against mosquito bites.
- Apply insect repellent containing DEET or other recommended substances.
- Remove standing water from items like toys or plant pots to eliminate breeding grounds.
- Use air conditioning and ensure window and door screens are well-maintained to keep mosquitoes out of homes.
Residents experiencing symptoms should seek medical advice promptly and mention any recent exposure to mosquitoes.
Since 2013, Texas has recorded 665 cases of dengue virus infection. Of these cases, 40 were locally acquired across various counties including Cameron and Hidalgo. With mosquitoes remaining active into November and December in much of Texas, public health officials urge continued vigilance.
