Immunization of kindergarten and first and second grade students in Mason County, Kentucky, aborted a measles epidemic and precluded epidemic spread when measles was repeatedly reintroduced into this county. The failure of measles to spread among unimmunized preschool children illustrates that susceptible children who congregate at schools, kindergartens, or other places are essential for epidemic transmission of the disease.
