Mumps epidemic spreads, more vaccine is promised

In the largest mumps outbreak in the U.S. in more than 20 years, almost 1,000 people have contracted the disease in the Midwest, the U.S. Centers for Disease Control and Prevention (CDC) announced Wednesday, April 19. The epidemic began in Iowa, where the State Department of Public Health has reported 815 suspected or confirmed cases. It has spread to at least seven other states. Because of the effectiveness of the vaccine introduced in 1967, most people think of the mumps as an illness that had been eradicated. About half of the cases in Iowa involve college−age students, most of whom have been vaccinated. Federal and state health investigators have not pinpointed the origin of the epidemic, but the first cases were identified in December on a college campus. Julie Gerberding, director of the CDC, said the disease had spread quickly because of the dense concentration of students in affected cities and because the vaccine is not perfect. It has about an 80 percent efficacy rate for people who have been inoculated with one dose, and a rate of about 90 percent for people who have received two doses. Gerberding said the CDC was providing an additional 50,000 doses of the mumps
