curred among children under 16 months old; and one occurred in a schoolchild who had not been vaccinated because of a history of physician-diagnosed measles. None of the cases was imported. Of the 11 (32%) preventable cases, five involved children under 6 years old who were not enrolled in day-care centers or preschool, and four involved adults 19-24 years old. These nine cases were defined as "hard-to-reach." Although conclusive epidemiologic links have been shown for only 19 (56%) of the 34 cases, this outbreak probably represents a single extended chain of transmission involving up to seven generations of spread. Editorial Note: A previous large outbreak of measles, involving primarily preschool-aged and school-aged Hispanic children, occurred in the Bronx in the spring of 1983 (1). Unlike the current East Harlem outbreak, several Bronx cases were traced to an imported case from Puerto Rico.
