The global incidence of dengue fever has reached a record high in 2024. Over 9.7 million cases were reported in the Americas, more than double the number in 2023. This alarming trend underscores the growing threat of dengue fever, particularly in the United States.

Dengue Fever Cases Surge in the US
The United States has witnessed a concerning rise in dengue fever cases. From January 1 to June 24, 2024, 2,241 cases were reported, including 1,498 cases in Puerto Rico. The severity of the situation prompted Puerto Rico to declare a public health emergency.
Travel-Associated Dengue Fever
A significant portion of dengue cases in the US is linked to travel. By June 24, 2024, 745 cases were reported among US travelers. This highlights the risk of contracting dengue fever while traveling to affected areas.
Local Transmission of Dengue
Worryingly, there have been instances of locally transmitted dengue fever in states with warm climates, including Florida, Texas, Hawaii, and Arizona. California also reported its first locally transmitted case in Pasadena last year. This indicates that dengue-carrying mosquitoes are establishing themselves within the US.
CDC Responds to Dengue Threat
In response to the escalating dengue fever risk, the Centers for Disease Control and Prevention (CDC) has issued a health advisory to raise awareness among healthcare providers and the public. The CDC is actively enhancing laboratory capacity and collaborating with local authorities to strengthen disease surveillance efforts.
Preventing Dengue Fever
Preventing dengue fever requires a multi-pronged approach. Individuals are advised to use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus. Wearing long-sleeved clothing and pants can also reduce the risk of mosquito bites.
Maintaining mosquito-free environments is crucial. Using air conditioning or ensuring window screens are intact can help keep mosquitoes at bay. Removing standing water, where mosquitoes breed, is also essential.
Public Health Actions
Public health authorities are urging individuals to seek immediate medical care if they experience fever or dengue symptoms, especially if they have recently traveled to areas with dengue outbreaks.
Travelers to regions with frequent or continuous dengue transmission are advised to take precautions against mosquito bites during and after their trips.

Conclusion
The increasing incidence of dengue fever, both globally and within the US, demands attention. While travel-associated cases remain a concern, the emergence of local transmission in several states necessitates heightened vigilance. By understanding the risks, taking preventive measures, and seeking prompt medical attention when necessary, we can mitigate the impact of this growing public health threat.
