A Fort Worth Independent School District employee has contracted the mumps, Tarrant County health officials say.
The employee works in the district's Professional Development Center, not a school campus, The Fort Worth ISD said Friday afternoon.
The announcement comes as the number of mumps cases has jumped both in Texas and nationwide.
A mumps outbreak in Johnson County has grown to 57 cases.
In Dallas County, eight adults have been diagnosed with mumps. Six of the cases were contracted at the same Halloween party, and two others are unrelated. One person traveled back from Minnesota and another from Arkansas, according to Dr. Christopher Perkins, medical director of the Dallas County Department of Health and Human Services.
Health officials also warned they expect to see even more cases over the next few weeks because of holiday travel.
Health officials believe a family trip to Arkansas is how the virus got to North Texas. It's part of a larger outbreak that has hit schools in almost every state this year.
There's no word from the CDC as to why this outbreak has been so severe. People who lack the proper immunizations are at the highest risk of getting the mumps.
The Texas Department of State Health Services is holding a vaccine clinc in Cleburne on Saturday from 6 to 8 p.m. The clinic will be held at 303 South Nolan River Road.
