Laura Brackett, the Executive Director for March of Dimes Milwaukee is discouraging pregnant women from traveling to Florida.

The warning comes after more cases show transmission from U.S. mosquitoes just north of downtown Miami.

 
"We are very concerned since it is now transmitted through mosquitoes in the United States," Brackett said Monday during a live interview on the CBS 58 News at 4. "We are discouraging people to travel in Zika infected areas. But that doesn't mean you can't prevent and be cautious here in the Milwaukee area."

Zika is spread through blood, sexual transmission and things like blood transfusions. But mainly its spread through mosquitoes.

There are five key ways to zap Zika according to March of Dimes:

Bug Spray. Deet is safe for pregnant women.

Get rid of standing water.

Don't expose skin. Wear long sleeves.

If you suspect you have it, go to a medical professional immediately.

Use air conditioning or make sure screens are on windows and doors.

(CBS NEWS) The CDC has issued an advisory urging pregnant women to avoid travel to the small area of Miami-Dade County in Florida where the Zika virus is being spread by mosquitoes.

The announcement comes after the Florida Department of Health confirmed Monday that 10 additional cases were transmitted through local mosquitoes in the one-mile radius just north of downtown Miami, bringing the total number to 14.

In a press briefing today, CDC director Dr. Tom Frieden said that in addition to pregnant women avoiding travel to the area known as Wynwood, pregnant women who live and work there should take every precaution possible to avoid getting bitten by mosquitoes.

This includes using an insect repellent with DEET, wearing long pants and long sleeves, staying indoors with air conditioning or window screens, and eliminating all standing water in and outside of homes where mosquitoes could breed.

Zika can also be spread through sex, so men and women who visit, live or work in this area should use condoms to avoid pregnancy and prevent spreading the virusto their partners, Frieden said.

People who have visited this area since June 15th (when the first infection is believe to have occurred) or later should avoid getting pregnant for eight weeks, health officials advised. Pregnant women who have visited the area on or after this date should be screened for Zika.

Zika is usually mild in adults and often causes no symptoms at all, but it is a much bigger hazard for pregnant women because the virus can cause severe birth defects.

The CDC has sent an emergency response team to Florida to assist in the ongoing investigation.
