Objective To understand the epidemiological characteristics of mumps in Bao’an District of Shenzhen City for the purpose of formulating scientific prevention and control strategies. Methods Epidemiological methods were used to analyze the epidemic data of mumps from 2009 to 2013 in Baoan District of Shenzhen City. The seasonality of mumps epidemics is described by the seasonal index. Results The number of mumps cases from 2009 to 2013 in Baoan District of Shenzhen City was 7677, with an average annual incidence of 34.41 / 100 000 and the highest incidence in 2011 (67.96 / 100 000). The months with season index greater than 100% were from April to July, of which the seasonal index in July was the largest (217.3%). The cases were mainly students, scattered children and preschool children, accounting for 31.84%, 26.20% and 16.26% respectively. Conclusions The incidence of mumps in Baoan District of Shenzhen City is concentrated in April to July. The vaccination rate of mumps vaccine should be raised in high-risk groups (children aged 5 to 9 years), monitoring of mumps in schools and nurseries, raising the handling capacity of epidemic situation and reducing the epidemic risks.
