And in more public health news, the measles outbreak has now hit over half of U.S. states. Sixty new cases were identified over the past week, bringing the total to 940 cases in 26 states so far this year. New York has the highest number of new infections, according to the Centers for Disease Control and Prevention. Experts expect the number of cases to exceed the outbreak of 1994, in which 958 cases were identified. Public health officials blame lower vaccination rates based on misinformation for the current surge in infected people. Meanwhile, Maine became the fourth state, along with California, Mississippi and West Virginia, to end most nonmedical exemptions for childhood vaccines.
