The Pasadena Public Health Department (PPHD) has confirmed the presence of locally acquired dengue fever in the area, marking a significant public health concern. A report published in the CDC's Morbidity and Mortality Weekly Report (MMWR) reveals that dengue was first identified in a Pasadena resident in October 2023, with no recent travel history.

Subsequent investigations found a second local case in Pasadena, indicating that dengue may be more widespread than initially thought. Manuel Carmona, Acting Director of Public Health, emphasized the need for community vigilance: "Recent cases highlight the importance of preventing mosquito breeding."

In 2024, nine local dengue cases were reported in Baldwin Park, El Monte, and Panorama City, with another in Escondido.

Prevention Tips

To reduce the risk of dengue infection, PPHD advises residents to:

• Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus
• Wear long-sleeved, light-colored clothing
• Fix window screens to prevent mosquitoes indoors
• Eliminate standing water in containers, gutters, and other items
