Abstract

Objective To analyze epidemiological characteristics of measles in Zhongshan City and to estimate the vaccine effectiveness (VE) of measles containing vaccine (MCV). Methods Descriptive epidemiological methods were applied to analyze the incidence of measles during the period from 2005 to 2018. A case-control study design was used to estimate the VE of MCV. MCV vaccination data were obtained from field survey of vaccination rate in Zhongshan in 2017 and 2018. Results A total of 6 516 measles cases were reported in Zhongshan from 2005 to 2018. The average annual incidence was 15.4/10⁵, ranging from 0.5/10⁵ (2017) to 63.7/10⁵ (2005). The incidence reached peak from April to September. The male to female ratio was 1.4:1. The majority of measles cases were scattered children (59.4%). 77.4% of meas-les cases aged from 8 months to 10 years had MCV unvaccinated. In 2017 and 2018, the vaccination rate of MCV in Zhongshan was 97.6% and 98.4% respectively, and the timely vaccination rate of the first-dose of MCV was 65.2% and 58.0% respectively. Among children aged 1-10 years, VE estimates were 93%(95% CI:89%-96%)and 96% (95% CI: 93%-98%) for one dose and two doses of MCV, respectively. Conclusions The incidence of measles decreased significantly from 2005 to 2018 and kept low in recent years, but the spread of measles virus was not interrupted. We should continue to strengthen measles surveillance, and maintain a high level of vaccination rate and timely vaccination rate of MCV, and finally achieve the goal of measles elimination.
