An outbreak of measles in West Texas has been reported by the Texas Dept. of State Health Services. 10 cases have been identified and seven of those have been hospitalized. Eight of the cases are among school-aged children.

The outbreak in Gaines County, with a population of about 22,000, has grown since two cases were reported in January. All those who contracted measles were unvaccinated, health officials said.

On January 30, officials reported two measles cases in unvaccinated, school-age children in Gaines County, which sits at the border of New Mexico and is around 90 miles southwest of Lubbock, Texas. Both children were hospitalized in Lubbock and had been discharged.

As another community in Texas confirms positive measles cases, here's what to know about symptoms of the highly contagious virus that impacts children.

Two of the four cases are in Lubbock, which hasn’t seen a case in more than 20 years. Measles vaccination rates in Texas have fallen over the last four years.

A measles outbreak is growing in a rural area of West Texas where vaccination rates are well below the recommended level.
