Dallas County confirms sexually-transmitted Zika case
Health officials say a patient in Dallas County has acquired the Zika virus through sexual transmission.
Dallas County Health and Human Services said Tuesday it received confirmation from the Centers for Disease Control and Prevention. The patient was infected after having sexual contact with an ill person who returned from a country where Zika was present.
The Zika virus is usually spread through mosquito bites. Investigators have been exploring the possibility the virus also can be spread through sex. It was found in one man's semen in Tahiti, and there was report of a Colorado researcher who caught the virus overseas and apparently spread it to his wife back home in 2008.
Health officials note there are no reports of Zika being locally transmitted by mosquitoes in Dallas county.
