Genetically modified mosquitoes could help Brazil combat the Zika virus, tests results released Tuesday by a British biotech firm suggest.

It's not entirely clear if Zika virus actually does cause birth defects but there's some strong evidence that it might.

According to official, the person who has tested positive for the virus in Hillsborough County recently traveled to Venezuela and two Miami-Dade County residents traveled to Colombia in December.

Yesterday, the Brazilian city of Piracicaba said it would expand the use of genetically modified mosquitoes to fight Aedes aegypti, the species that spreads dengue and chikungunya as well as the Zika virus.

Besides South America and Puerto Rico, outbreaks of Zika virus have been reported in the past in Africa and Southeast Asia.

Zika has been linked to potentially fatal birth defects in Brazil, where authorities are investigating a spike in newborns with microcephaly, or underdeveloped brains.

On Friday, the CDC came out with an alert asking pregnant women - at any stage of pregnancy - to postpone travel to 14 destinations in Latin America and the Caribbean.

Zika virus is spread to people through mosquito bites, similar to West Nile virus, and can cause fever, rash, joint pain and red eyes for several days to even weeks. She was likely infected while living in Brazil, Hawaii health officials said.

Mosquitoes carrying Zika have turned up across the Americas and the Caribbean.

The CDC says there were 30 times more cases of Zika reported in Brazil last year than in any year since 2010.

It's the first case of brain damage linked to the virus in the United States.

The alert followed reports in Brazil of microcephaly in babies of mothers who were infected with the virus while pregnant, but researchers have said additional studies are needed to determine the relationship, if any, between the virus and the defect.

The CDC is working on guidelines to care for pregnant women who may have been exposed.

What should you do if you contract Zika? If an uninfected mosquito bites an infected human, that mosquito can then transmit the pathogen to other humans. Because there is no commercial test for Zika virus, doctors will need to work with state or local health departments to facilitate testing for their patients, the CDC said.

"They all can be combated in the same way", Dr. Park told HuffPost, after highlighting the need for a state-wide campaign that raises awareness and educates the public on the dangers of mosquito hot-beds like standing water.
