[Objective]To investigate the epidemic features and trends of measles in Heping district,Shenyang city, so as to provide theoretical basis for strategies of measles elimination scientifically. [Methods]Using descriptive epidemiological method,the data of measles during 2006-2010 were analyzed systematically. [Results]A total of 255 cases of measles were reported accumulatively during 2006-2010 and the average annual incidence rate was 7.18/10^5. The incidences of measles were 17.17/10^5 ,0.14/10^5 ,2.65/10^5 , 14.90/10^5 ,and 1.84/10^5 during 2006-2010 respectively. The average annual incidence rates were 264.35/10^5 ,22.21/10^5 ,20.54/10^5 ,15.31/10^5 ,and 21.15/10^5 for the age group of G1,1-2,3-6,7-14 and 15-54 years old during 2006-2010（ P 〈0.01）. The average annual incidence rate in males was 8.29/10^5 ,and 6.00/10^5 in females（ P 〈0.05）. The average annual incidence rate in the urban and urban fringe area was 6.15/10^5 ,and 52.47/10^5 in the rural area（ P 〈0.01）. The cases of domestic unemployment, scattered children, students and kindergarten children, other occupation accounted for 33.33 %, 22.75 %, 14.90% and 29.02 % respectively in the 255 cases. There was high incidence from March to June, accounting for 84.31%. Cases which had immune history accounted for 37.26 %. There were 250 scattered cases, accounting for 98.04%. [Conclusion]The incidence of measles in Heping district tends to decrease slightly, the incidence in the urban area is higher, and the cases of domestic unemployment are high-risk population.
