MIAMI — Health officials in Florida are investigating what could be the first Zika infection from a mosquito bite in the continental United States, involving a resident of the Miami area.

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 person has 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.

More than 1,300 Zika infections have been reported in the U.S., none involving bites from local mosquitoes; 14 of these were sexually transmitted and one lab worker was stuck with a contaminated needle.

Miami-Dade County has the most confirmed infections in Florida so far – 88, but all have involved someone who traveled to areas such as Latin America and the Caribbean where Zika outbreaks are widespread.

Health officials predicted the virus would reach U.S. mosquitoes this summer and have mobilized to keep Zika from spreading.

Mosquito control inspectors have been going door-to-door in the Miami area under investigation since health authorities alerted them late last week, spraying to kill mosquitoes and emptying containers of the water they need to breed.
