The number of people with measles in Texas increased to 146 in an outbreak that led this week to the death of an unvaccinated school-aged child, health officials said Friday. The number of cases — Texas’ largest in nearly 30 years — increased by 22 since Tuesday.

Twenty-five years after the disease was declared “eliminated” in the U.S., cases are rising again, with a Texas outbreak now spreading to New Mexico. Measles cases continue to rise in the United States nearly two and a half decades after the virus had been declared eliminated in the country.
