A Dallas County resident has become the first Zika patient to contract the virus in the U.S. without traveling abroad, according to the Centers for Disease Control and Prevention. County health officials said the patient was infected through sexual contact, not through a mosquito bite.
Dallas County Health and Human Services said the patient was infected after having sexual contact with an individual who developed symptoms after returning from a trip to Venezuela. The individual from Venezuela is also infected with the virus.
“A person who recently traveled to an area with Zika virus transmission returned to the United States and developed Zika-like symptoms. The person later tested positive for Zika, along with their sexual partner, who had not traveled to the area,” the CDC said in a statement.
Neither is pregnant. Both are thought to still be in Dallas County.
DCHHS said Tuesday that the CDC confirmed the Zika test and that the county health department confirmed the virus was transmitted sexually through a follow-up interview with the patient. The CDC’s statement did not confirm or rule out that the virus was transmitted sexually.
