New details on first Fla. mosquito-bite Zika cases

MIAMI, Fla. (WPVI) -- We're getting a few more details about the first people to get the zika virus from mosquitoes in South Florida - and the questions they raise.

Just this afternoon, we learned there is one more case of Zika virus not related to travel in South Florida. That brings the total to 22.

Officials continue to say all the cases are connected to a small area North of downtown called Wynwood.

But a new report in the Wall Street Journal is raising some questions.

It says one of the first cases in Florida - A pregnant woman - Has no clear connection to that area.

Two other people infected also don't have any connection to the neighborhood.

This calls into question whether that is the only area with active Zika spreading by local mosquitoes.

Aerial spraying was done over the Wynwood area again this morning.

Miami-Dade County's mosquito control director says the insect's population is dropping in the Miami neighborhood health officials have linked to 21 Zika infections.

Chalmers Vasquez said his department finds just one mosquito a day in each trap in the Wynwood district.

He said two weeks ago, about two dozen mosquitoes were found in the traps daily.

The county's 12-person mosquito control staff has ballooned to nearly 100 people, with the addition of contractors.

In addition to the aerial and truck spraying, teams are dropping insecticide into 150,000 storm drains.

New Jersey U.S. Sen. Bob Menendez can add a personal motivation to his efforts to get Congress to approve federal funding to combat the spread of the Zika virus.

Menendez said this week his daughter is five months' pregnant in Miami with his first grandchild.

Pregnant women are being cautioned not to visit parts of Miami where the virus has been detected.

The Centers for Disease Control estimates more than 7,300 Americans have been infected.

Last week, Menendez joined Senate Democrats including New Jersey Sen. Cory Booker to ask Republican congressional leaders to call Congress back into session to pass emergency funding legislation.
