Objective To investigate the epidemiological characteristics of measles cases of new genotype D8 in Beijing from January to June,2013.Methods Epidemiological survey and descriptive analysis was conducted.Results 661 suspected measles were reported from January to June,2013.416 were confirmed measles cases by serology and etiology detection.28 measles cases were caused by genotype D8 measles virus by genotype identification.There were 2 measles outbreak including 14 cases and 14 sporadic cases.The incidence peak was during April and May.25 cases (89.3％,25/28) occurred in downtown and suburban districts.22 cases (78.5％,22/28) were adults aged 15-39 years and 19 cases (67.9％,19/28) were migrant population.12 cases (85.7％,12/14) in outbreak were migrant population working in clothing sales.There was epidemiological association between 2 outbreaks.Conclusion Measles cases of genotype D8 were found for the first time in Beijing.Genotype D8 virus mainly infected migrant adults and caused local outbreak and endemic.
