The measles outbreak that began in West Texas is still growing, with exposures on university campuses and other places in San Antonio and San Marcos.

A Texas measles outbreak has doubled in the last week to 124 cases, state health officials said Tuesday, a day after they warned a person infected with the highly contagious disease had traveled from the outbreak zone.

The Texas measles outbreak is up to 124 cases in 9 counties, according to the latest numbers by the Texas Department of State and Health Services.
