Florida’s Broward County Health Department announced a confirmed case of Dengue in a woman who had not left the county for weeks. Broward County is now only the second location in the US to document a locally acquired case (Key West has seen 53 cases this year). For decades, almost all dengue cases in the 48 continental US states acquired the disease during international travel or visits to more tropical US locations (e.g. Puerto Rico and the US Virgin Islands). The identification of this locally acquired case means that a mosquito in Broward County was carrying Dengue and transmitted to the confirmed case. Therefore, other residents in the county are likely at risk as well..
