Abstract To understand the epidemic of measles in China in the past 20 years, such that to provide important information for dynamical models and to provide theoretical basis and suggestions for control measures to eliminate measles. Reviewed related literature in the past two decades on studies of measles in China, including the epidemiology characteristics of measles, vaccination coverage, supplemental immunization activities (SIA) and their effects, serological investigation in population and the possible driving factors for cases annual seasonality. Reported cases in the post-vaccination era still had annual seasonality, however seasonal peak shifted to late Spring; case percentage in age groups shifted and the percentage in elder population increased; the overall immunization rate of measles in China has reached a high level, but the vaccination coverage in urban and rural areas are uneven; SIA had significant effect on the reduction of measles cases there is a significant correlation between the number of cases of measles and the environmental factors. A nationwide comparative analysis in the epidemiology of measles is lack; it is necessary to study the vaccination coverage difference between rural and urban areas; it is worth to apply dynamical transmission models to analyze the persistent prevalence of measles in China even though there has been a high level vaccination implemented.
