The Zika virus, which can be dangerous for unborn babies, has been transmitted through sex in the United States, health officials said Tuesday.
Up until now, only mosquitoes were thought to be transmitters.

The Centers for Disease Control and Prevention confirmed that a patient in Texas is the first case of Zika acquired inside the U.S., and that it was sexually transmitted.
"Dallas County Health and Human Services has received confirmation of a Zika case associated with acquiring locally,” said Dr. Christopher Perkins of Dallas County Health and Human Services. “We have received confirmation that it has spread otherwise through sexual activity."
Up until now, all other U.S. cases were thought to be from travelers who were bitten by a mosquito while in Latin America and then returned to the U.S.
Also on Tuesday, the Florida Department of Health reported six new cases of the Zika virus in the state.
State health officials think the virus was acquired outside of Florida. It brings the total to nine travel-related cases of the Zika virus in Florida:
- Miami-Dade: 4 cases
- Hillsborough: 2
- Lee: 2
- Santa Rosa: 1
Zika has been linked to a birth disorder in newborns that results in babies born with small heads, causing severe developmental issues and sometimes death. Infected patients often report no symptoms.
The Florida Department of Health officials recommend that residents and visitors protect themselves from mosquitoes by draining standing water, covering skin with repellent and clothing and covering windows with screens. They’re concerned mosquitos carrying the Zika virus will make their way to Florida.
The CDC says mosquitoes are still the primary vector for Zika spreading to at least 24 countries. But with this latest case in Texas, health officials are recommending partners use protection during sex.
