Epidemiological characteristics analysis of rubella and discussion of its control strategies in Fengxian District of Shanghai, 2003-2015

ObjectiveTo analyze the epidemiological characteristics of rubella in Fengxian District of Shanghai, 2003-2015, and to provide evidence for rubella control.

MethodsData on rubella cases in 2003-2015 were obtained from the Infectious Disease Reporting System of Shanghai, and analyzed by descriptive epidemiologic methods.

ResultsA total of 518 rubella cases were reported in Fengxian District, in 2003-2015, with annual average incidence of 4.32 per 100 000 population. Yearly incidence ranged from 3 (2005, 2013, 2014) to 185 (2007), and incidence rates ranged from 0.26 per 100 000 population (2014) to 21.81 per 100 000 population (2007). The incidence in males was higher than that in females. Most cases occurred in 20 to 39 years old. The peak season was from April to July. Cases in local population were more than those in migrant population. Cases with no or unknown immunization with rubella-containing vaccine (RCV) were more than those with RCV immunization.

ConclusionThe rubella epidemic was generally within the controllable range from 2003 to 2015 in Fengxian District, and the incidence rate has been kept at a low level in recent years. We suggest to strengthen rubella surveillance and promote routine immunization in children and/or supplementary immunization activities in immigrant workers.
