Florida steps up efforts to combat Zika; Philadelphia takes precautions

Teams have stepped up their efforts to stop the spread of mosquitoes carrying the Zika virus in South Florida.

And Philadelphia is launching a campaign to make sure the virus doesn't make its way here.

Planes with insecticide were ready to go early Wednesday morning, but aerial spraying was postponed due to stormy weather. The air assault was rescheduled for later in the day.

But it's unclear how well it will work - this type of mosquito sticks close to the ground, not high up in the air.

Still, officials say it's worth a try.

They've also stepped up their ground efforts, tripling the number of inspectors going door to door.

And many medical clinics in Miami are now testing every pregnant woman.

"Regardless if she lives in an area of concern or not, she's going downstairs to have blood work done," said Juliana Duque, Nurse Practitioner in South Florida.

While the battle continues in Florida, so does the fight for funding from Congress. Right now, government health agencies are borrowing funds from other programs, but money will run out.

As for whether we'll see Zika spread in our area, Dr. Eric Sachinwalla, an infectious disease expert at Einstein Medical Center, says, "I think it's possible, but I think it's less likely than seeing cases in South Florida."

Just in case, Philadelphia is preparing. The city's department of public health has launched an information campaign.

There are no locally-transmitted cases of Zika, but residents are still urged to protect themselves from mosquitoes.
