As severe floodwaters slowly recede across western Broward County after days of heavy rain, public health and city officials are warning that standing water could lead to more mosquitoes carrying viral illnesses, including dengue.
The downpours flooded Davie and nearby communities, closed local schools, stalled vehicles on flooded roads and kept some residents trapped in their homes. Floodwaters began dropping Friday, but several recreational areas, including Oakhill Equestrian Park, remained closed because of standing water.
Local authorities said pooled, stagnant water is an ideal breeding ground for mosquitoes. The concern comes as Florida tracks elevated dengue activity statewide. The Florida Department of Health has logged nearly 300 dengue cases this year, according to its data. State health officials reported no confirmed dengue cases in Broward County this month, but medical experts said prolonged ponding after storms raises the chance of local spread.
Dr. Craig Harrison of Broward Health Medical Center said dengue can cause fever, body aches and headaches, often felt behind the eyes. In severe cases, patients may develop a rash or bleeding.
The Town of Davie has started mosquito spraying. Municipal crews are assessing neighborhoods to decide whether more ground fogging or aerial treatment is needed before larvae mature.
Health agencies recommend the “Drain and Cover” approach: emptying standing water from flower pots, gutters, pet dishes and pool covers, using repellent containing DEET, and wearing long sleeves during peak mosquito hours.
