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.

Measles was considered to be eliminted in the U.S. in 2000, thanks to vaccine developments. But vaccination rates have dropped since the covid pandemic began.
