San Diego County has reported its first locally acquired case of dengue fever, marking a significant milestone in the region's fight against mosquito-borne diseases. The infected person, an Escondido resident, had not traveled to areas where dengue is common, indicating local transmission.

To prevent the spread, County Vector Control has begun spraying for mosquitoes at around 170 homes in Escondido. The treatments, which started Friday, will continue until October 10. These efforts follow similar treatments conducted in Oceanside and Mount Hope earlier this year as a precautionary measure.

Dengue, typically found in tropical regions, is spread when an infected mosquito bites a person, and it can cause symptoms like fever, chills, aches, and rashes. Severe cases may require hospitalization.

Residents are encouraged to take preventive measures such as dumping standing water, using EPA-approved insect repellents, wearing long sleeves, and ensuring window and door screens are intact.
