MIAMI (AP) – Health officials in Florida are investigating whether the Zika infection of a woman in the Miami area could be the first transmission of the virus from a mosquito bite in the continental United States.

Lab tests confirmed the Zika infection, according to statements from the U.S. Centers for Disease Control and Prevention and Florida’s Department of Health.

Health officials said the case had no apparent links to recent travel outside the country. They did not immediately respond Wednesday to questions about ruling out other methods of transmission, such as sex.

The patient is an adult woman who lives in Miami-Dade County, according to a health official familiar with the case who wasn’t authorized to reveal details beyond the statements of the agencies involved, and thus spoke on condition of anonymity.

No other details about her case were released.
