MIAMI — Florida health officials have trapped mosquitoes in an area of Miami-Dade County and are testing them for Zika to confirm whether a woman with the virus could be the first person infected directly by a mosquito bite in the continental United States.

Florida’s Department of Health and the U.S. Centers for Disease Control and Prevention did not immediately respond to questions about their investigation, but health officials said the case had no apparent connection to travel outside the country.

The patient is a 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.

“Mosquitoes have been trapped in the area of investigation and are being tested,” Health Department spokeswoman Mara Gambineri said in an e-mail Wednesday.

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 needle.

Officials predicted that would change this summer once the virus reaches U.S. mosquitoes and have mobilized to keep Zika from spreading beyond isolated clusters of cases.

Miami-Dade County has the most confirmed infections in Florida — 89 — but so far all have involved someone who traveled outside the U.S. mainland to areas with Zika outbreaks, such as Latin America and the Caribbean.

The White House said President Barack Obama had spoken by phone with Florida Gov. Rick Scott regarding the new Zika case. The president noted during the call that besides the $2 million the CDC already provided to Florida, the agency anticipates awarding Florida another $5.6 million in Zika funding through a grant this week.

According to a CDC response plan, health officials would want to see more than just one unexplained case before declaring that someone has been infected by a mosquito bite in the continental United States.
