MIAMI (CBSMiami) – The aerial spraying to kill mosquitoes in the fight against the spread of the Zika virus is hit or miss right now.

Zika 101: Prevent Spread By Protecting Yourself

The Centers For Disease Control and Prevention (CDC) said the spraying is working in Wynwood - where two pesticides are being used to kill both adult mosquitoes and mosquito eggs, but that's where the good news ends.

In other parts of the Zika zone, mosquitoes, in particular, the breed that carries the Zika virus are thriving.

The CDC says this is because those areas are not getting the double dose of pesticides. The department's initial advice to Miami-Dade County was a single pesticide treatment in areas that didn't have active transmission of Zika.

It remains unclear if the procedures will change.

As of Tuesday, the Florida Department of Health's daily report shows 12 new travel-related cases with one involving a pregnant woman, and no new non-travel related cases.

In another development, One Blood told CBS4's Tiani Jones in a statement that they "continue to test every unit of blood donated." They also said, "any positive results are immediately reported to the Florida Department of Health."

On Tuesday a man in El Paso, Texas who recently visited Wynwood has contracted the virus.

"We only heard it on the TV," said German tourists Evelin Auerswald, "We thought its only in Brazil and now it's here."

A new CBS poll asked people, "How comfortable would you be traveling to places affected by Zika in the U.S.?

More than half of the people polled wouldn't be comfortable. Twenty-six percent said not too comfortable and 32 percent said not at all comfortable.

A big chunk also said they were concerned about an outbreak of Zika in the U.S. Twenty-six percent said they're very concerned and 38 percent somewhat concerned.

And while many have heard of the Zika transmission in Wynwood, but they're still coming. Those who are still choosing to come to the area, most of them associate Zika with pregnant women or women trying to become pregnant and therefore have little fear of the virus.

"I mean, I'm not worried about it because I mean I just think that it's not going to affect me," said a girl walking through Wynwood.
