CDC is dispatching additional staff to Florida after the state’s governor, Rick Scott, on Monday called for a federal emergency response team. Members of the team will be assisting with measures like lab testing and mosquito control. Officials believe the virus began spreading in a small area just north of downtown Miami in early July.
Officials are especially concerned that mosquitoes have not dissipated despite insect-control efforts. Scientists are are trying to discover whether the mosquitoes are resistant to insecticides or if larvae are hiding in places that are difficult to reach.
