The death, reported on Wednesday, was the first U.S. fatality from the highly contagious disease in a decade. Government data showed a growing outbreak

Mexia ISD updated its notice to the public about a possible measles exposure to say a school nurse confirmed it is a case of rubella.

State health officials insisted on Friday that there have been no confirmed cases of rubella or measles in Central Texas. However, Brazos Valley health officials are calling a couple of false alarms in Mexia a wakeup call.

After first reporting a confirmed case of measles, Mexia ISD said it was actually Rubella. The state health department says neither is true.

The main measles outbreak has been in the South Plains region of West Texas, where 124 cases have been confirmed. Most of the cases have been among unvaccinated children, although five people who are vaccinated have been among the cases, according to health officials.

The Mexia ISD confirmed a rubella case, initially misreported as measles, due to a miscommunication with a parent.
