[Objective]To understand the situation of serological monitoring and epidemiological characteristics of measles in Xinyang City from 2009-2011,and provide scientific evidence for measles control and elimination.[Methods]The epidemiological characteristics and laboratory test results of suspected measles cases from 2009-2011 were analyzed.[Results] From 2011 to 2009,a total of 818 suspected measles cases were reported,540 was measles IgM antibody positive.The laboratory-confirmed rate was 66.0%.The peak incidence appeared in 2009,with 448 cases.Most cases concentrated in March to June,with 423 cases,accounting for 78.3% of all cases.Four hundred and forty-one cases were children aged 0-7 years,which accounted for 81.7% of total cases.The groups with most cases were scattered children（64.8%）,students（24.4%） and farmers（5.0%）.The first 5 districts with most laboratory-confirmed cases were Pingqiao District（100.0%）,Shihe District（95.2%）,Xin County（87.4%）,Xi county（84.9%） and Huangchuan County（82.1%）.[Conclusion]It is necessary to strengthen the measles vaccination of children and implement the supplementary immunization.The management of vaccination should be further strengthened,especially the management of floating population,and the immunization coverage and timely vaccination rate should be strengthened.
