[目的]探讨强化免疫对麻疹流行病学特征有何影响。[方法]对比2008年强化免疫麻疹疫苗后某市麻疹的发病情况。[结果]该地区2005~2008年麻疹报告病例数412,报告中,年发病率依次为8.03/10万、20.23/10万、14.76/10万、26.79/10万。其中5至8月份发病总数为总病例数的71.84%(296/412)。其中15岁以下麻疹患儿占85.19%(351/412)。麻疹患者中婴儿所占比例分别是18.75%、14.29%、20.69%及22.78%,其中麻疹疫苗接种史准确只有24%。从2008年10月份开始进行强化免疫接种麻疹疫苗,在2009年病例数只有14例,发病率仅为2.08/10万,比2008年降低了92.24%。[结论]强化免疫接种麻疹疫苗后效果明显。
[Objective] To investigate the impact of booster immunization on the epidemiological characteristics of measles. [Method] Contrast the incidence of measles in a city after the 2008 immunization with measles vaccine. [Results] The number of reported cases of measles from 2005 to 2008 in this area was 412, with the annual incidence rates of 8.03 / 100,000, 20.23 / 100,000, 14.76 / 100,000 and 26.79 / 100,000 respectively. The total number of cases from May to August was 71.84% (296/412) of the total number of cases. Among them, 85.19% (351/412) of measles children under 15 years of age. The proportion of infants in measles patients was 18.75%, 14.29%, 20.69% and 22.78% respectively, of which the measles vaccination history was only 24%. Since October 2008, there has been only 14 cases of measles vaccine boosted in 2009 with a prevalence of only 2.08 / 100,000, a decrease of 92.24% over 2008. [Conclusion] The effect of intensive immunization of measles vaccine is obvious.
