Measles transmission among adults with spread to children during an outbreak: Implications for measles elimination in China, 2014.

Our investigation highlights adult susceptibility to measles.METHODS: We conducted a retrospective active case search, and analyzed confirmed case data to describe person, place, and time characteristics of the outbreak. All individuals with measles with onset during the first 2 months of the outbreak were interviewed face-to-face to determine source(s) of infection and transmission route (from whom and to whom).RESULTS: Among the 280 cases, 220 (77.6%) were among≥20-year-old adults, 24 (8.6%) were among 8-23 month olds, 22 (7.9%) were among
