## Executive Summary
Florida is scaling up mosquito control and aerial treatments as dengue fever cases double in one week, with Hillsborough County identified as the epicenter.

## Intelligence Brief
Florida is currently managing a surge in locally acquired dengue fever cases, with a specific focus on several counties. According to reports from WFLA and Outbreak News Today, Hillsborough County has been identified as the epicenter of the outbreak. The situation has escalated rapidly, with WFLA reporting that the total number of dengue fever cases across the state doubled within a single week. In response, Hillsborough County has deployed helicopters to treat mosquito populations. This effort has been bolstered by Manatee County, which according to wtsp.com, has provided its own helicopters and a pilot to assist Hillsborough County in the fight against the spread of the virus. Coverage from multiple outlets emphasizes the regional nature of the response and the urgency of the containment efforts.


Spectrum News 13 and OCFL Newsroom report that Orange County has increased its mosquito control and surveillance efforts, specifically targeting the Pine Hills area following a reported dengue case. The Florida Department of Health has also intervened, with the Florida Surgeon General issuing reminders to residents to take necessary precautions against dengue. These warnings were specifically timed to precede the Labor Day weekend to ensure the public remained vigilant during a period of high activity. To understand the current stakes, it is necessary to note that the cases appearing in these reports are locally acquired, meaning the virus is being transmitted within the state rather than being imported from travel. The involvement of multiple county governments—Hillsborough, Orange, and Manatee—indicates a coordinated public health response to prevent further geographical expansion. The use of aviation assets for treatment highlights the scale of the infestation and the difficulty of managing mosquito populations on the ground in high-risk areas like the reported epicenter.


Moving forward, the focus remains on resident cooperation and intensified surveillance. OCFL Newsroom reports that Orange County is actively encouraging residents to take preventive actions to protect themselves and their communities. Monitoring will continue in Pine Hills and across Hillsborough County to determine if the aerial treatments and increased surveillance successfully slow the rate of infection. Public health officials will likely continue to monitor the case counts as they track the effectiveness of the coordinated efforts between the Florida Department of Health and local county mosquito control teams.
