CDC: Measles cases highest in 6 years
Measles outbreaks in several states have led to more than 70 cases so far this year, the worst in six years, health officials said Thursday. Most of the cases have been traced to outbreaks overseas and are mainly in children who were not vaccinated for religious or other reasons, according to the Centers for Disease control and Prevention. Since measles vaccinations began in the early 1960s, cases have dramatically declined in the U.S.
