The measles outbreak in Texas has reached nearly 150 cases, according to a Friday morning update from the state health department. The agency said 146 cases have been identified since late January. Twenty of those patients have been hospitalized, and one school-age, unvaccinated child has died.

A Texas doctor warned people not to attend "measles parties" after the virus infected more than 100 West Texas residents over the past few weeks. Newsweek reached out to the Texas Department of State Health Services (DSHS) for comment via email.
