A child who was not vaccinated has died from measles in West Texas. It's the first death in an outbreak that began late last month and the first from measles in the U.S. since 2015.

Now 124 people infected in West Texas, nine more in New Mexico and outbreak 'still has a lot of energy and steam behind it.'

The Mennonite population being affected by a measles outbreak in West Texas is part of a larger, loosely affiliated group of churches worldwide.
