Measles is one of the most contagious diseases in the world. It was eliminated in the United States 25 years ago because of an effective vaccine. While cases periodically pop up, a growing wave of vaccine skepticism is giving this old virus new traction.Health reporter Fenit Nirappil and “Post Reports” producer Elana Gordon recently traveled to the heart of this growing outbreak, which officials say may take months to get under control.  Today, Martine Powers speaks with Fenit about the state of the Texas outbreak; we hear from a mom whose unvaccinated child recently got measles and from a pediatrician who has cared for hospitalized patients. Today’s show was produced by Elana Gordon, who also contributed to this report. It was edited by Peter Bresnan with help from Reena Flores and Maggie Penman, and mixed by Sam Bair. Thank you to Lenny Bernstein.Subscribe to The Washington Post here.
