Katherine Wells, the public health director in Lubbock, Texas, describes her fight to stop the largest measles outbreak since 2000, despite a chaotic reorganization of federal health agencies.

The measles outbreak centered in northwest Texas appeared to slow on Friday, as health officials reported just seven new cases since earlier this week. The latest update from the Texas Department of State Health Services shows the state has seen 709 measles cases since the outbreak began spreading in late January.

Texas' measles outbreak that began in Gaines County in January has now expanded to 709 cases, officials said on May 9.
