(Reuters) – Texas officials on Monday reported the state’s first case of the Zika virus that was likely transmitted by a local mosquito, expanding the spread within the continental United States of a virus that has been linked to microcephaly, a rare birth defect.

The case involved a woman living in Cameron County near the Mexico border, the Texas Department of State Health Services said. The state said it currently has no other suspected cases of local transmission.
