First sexually transmitted case of Zika virus is confirmed in the US, health officials warn

A patient diagnosed with the Zika virus in Texas became infected after having sexual contact with another sufferer, health experts said today.

It marks the first case of sexual transmission of the virus in the US, the Centers for Disease Control and Prevention confirmed.

Dallas County health officials said the patient’s partner fell ill after visiting a country where Zika is rife.

While six people in Harris County, close to Houston, have contracted the disease after traveling to affected regions, this is thought to be the first case of a person becoming infected on US soil, having not traveled.
