The Texas Department of Health and Human Services announced the first case of Zika virus in Texas transmitted by a mosquito. The case is in Cameron County, which is in the Rio Grande Valley.

According to a press release issued Monday, the patient is from Cameron County and is not pregnant. Lab tests were confirmed last week through patient's urine, but not the blood stream, which means the virus can no longer be spread from her by a mosquito.

"We knew it was only a matter of time before we saw a Zika case spread by a mosquito in Texas," said Dr. John Hellerstedt, DSHS commissioner. "We still don't believe the virus will become widespread in Texas, but there could be more cases, so people need to protect themselves from mosquito bites, especially in parts of the state that stay relatively warm in the fall and winter."

Cameron County, DSHS and the Centers for Disease Control and Prevention are working together to investigate and respond to this case.
