U.S. authorities have urged pregnant women not to travel to a Miami neighborhood after Florida detected 10 more cases of Zika caused by the bite of local mosquitoes, bringing the total to 14.
U.S. Centers for Disease Control and Prevention or CDC on Monday recommended pregnant women who have visited the one-square-mile area just north of downtown Miami to talk with their doctors and take tests for Zika.
At Florida’s request, the CDC is also sending an emergency response team to assist in the situation.
On Friday, Florida Governor Rick Scott announced the first four locally spread cases of Zika in the continental United States.
Before that, more than 1,600 Zika cases have been reported in the country, but none of which are locally spread cases.
Most people infected with Zika will not have symptoms. However, Zika infection during pregnancy can cause a serious birth defect of the brain called microcephaly and other severe foetal birth defects.
