Nine South Florida schools began the fall term this week on Zika alert, after more than a dozen cases of locally transmitted virus have been reported in the surrounding one-square-mile area. Crews from the Miami Dade County Public Schools have been eliminating standing water, where mosquitos breed, in Miami’s Wynwood and Midtown neighborhoods, according to the Miami Herald. Officials have also sent voice messages to parents advising them to dress their children in long-sleeve shirts and long pants, despite the summer heat, and to apply insect repellent before they leave home.
