The county did not identify the person infected. The CDC said it did not investigate how the virus was transmitted.
There have been six confirmed travel-related cases of Zika virus disease, all among residents of Harris County, where Houston is located, the Texas Department of State Health Services said.
In medical literature, there has been only one case of Zika transmitted sexually and one case in which the virus was detected in semen.
