The measles outbreak in rural West Texas has grown to 58 cases as of Tuesday, and eight people in neighboring eastern New Mexico also have been diagnosed with measles. New Mexico health department spokesman Robert Nott said Tuesday that the agency hadn’t “identified any direct contact” between cases in its state and cases in Texas.

An ongoing measles outbreak that began in one of Texas' least vaccinated counties has mushroomed to 90 cases across a cluster of seven counties in the state, according to an update by the Texas Department of State Health Services on Friday.

When the local hospital warned of a brewing measles outbreak, Kaleigh Brantner urged fellow residents of this rural West Texas community to beware of vaccinating their children. Two weeks later, her unvaccinated 7-year-old son came home from school with a fever.
