Abstrakt:	Objective: To evaluate the development and operation on measles surveillance system. Methods: To formulate surveillance program, and then establish surveillance system on measles in Hainan province before the case surveillance was conducted. Descriptive epidemiological method was used to analyze the measles cases reported through the notifiable diseases epidemic situation report system and measles surveillance system during 2004 - 2008 in Hainan province. Results: From 2004 to 2008, through surveillance system, 3040 suspected measles cases were reported which was 96.00% higher than that from the notifiable diseases epidemic situation report system. When the measles surveillance system was first established in 2004, the number of cases reported by the surveillance system was less than that from the epidemic report system, however, the sensitivity of the surveillance system had been increasing since 2005. In 2008, the number of suspected cases reported by surveillance system was 19.12 times more than from the epidemic report system. The proportion of confirmed cases in the total suspected cases was decreasing annually, from 90.34% to 4.48%, along with the increase of the sample collection rate, from 22.73% to 99.12%. The proportion of laboratory confirmed cases in the total confirmed cases increased from 7.55% to 86.97%. With suspected cases, the IgM antibody positive rate on measles and rubella were 31.57% and 34.52%, respectively. In Hainan, the epidemic pattern of measles had been sporadic, except for 2006 as there occurred several outbreaks in that year. The of disease incidence had an obvious seasonal peaks, from March to June. Measles mainly attacked children under 15 years of age, accounted for 86.68% of the age group. Children with no immunity or unknown immune history accounted for 85.67%. Conclusion: The sensitivity of surveillance system had been increasing annually since it was developed and the incidence had been dropping to its lowest level. These achievements had built a solid foundation for the eventual elimination of measles.
