A baby girl in Texas has died due to a Zika-related condition, marking the first official death due to the mosquito-borne virus in that state.

The baby was born with microcephaly, a condition in which a baby’s head is much smaller than expected, and in many cases halts brain development. The mother had traveled to Latin America during her pregnancy and acquired the Zika virus there.

Peter Horetz, dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, told USA Today that although this is the first death in Texas, “we should expect many similar deaths, and also stillbirths” related to Zika.

Since the breakout of the disease, 15 babies have been born in the U.S. with Zika-related defects, reports USA Today. In addition to that, seven women have miscarried pregnancies due to the disease — and doctors expect that number to grow.

Miami has seen the most cases in the United States so far, where the neighborhood of Wynwood has 17 infected people, according to USA Today.

“Zika’s impact on unborn babies can be tragic, and our hearts are with this family,” John Hellerstedt, commissioner of the Texas Department of State Health Services told USA Today. “Our central mission from the beginning has been to do everything we can to protect unborn babies from the devastating effects of Zika.”
