辽宁省在麻疹疫苗 (MV)使用前 (1949～ 196 5年 ) ,麻疹报告发病率一直在 5 0 0 / 10万左右 ,居法定报告传染病的首位。流行曲线呈隔年一次高峰。自普遍使用MV后 (196 6～ 1978年 ) ,麻疹发病率降至 10 0 / 10万 ,流行曲线仍是隔年一小流行的周期。在实施计划免疫的初期 (1978～ 1984年 ) ,麻疹发病率持续下降 ,打破了隔年一个流行高峰的规律。 1985年后使用冻干MV ,免疫程序与全国统一 ,麻疹发病率逐年下降 ,1999年报告发病率为 0 5 2 / 10万 ,为历史最低水平。麻疹的地区分布无特殊规律。使用MV后 ,麻疹发病主要在 3～ 5月 ,以 2 5岁以下人群为主 ,呈现向大年龄组后移的现象。 1997～ 1999年麻疹发病以中小学生最多 ,约占 40 % ;其次是散居儿童 ,占 2 0 %。今后应继续加强冷链建设 ,提高疫苗接种率 ,认真做好麻疹疫情的主动监测和实验室监测 ,及时隔离传染源 ,彻底处理疫点和疫区 ,根据实际情况开展对高危人群的强化免疫 ,以达到控制和消除麻疹的目的
Before the measles vaccine (1949 ~ 196 5) was used in Liaoning Province, the incidence of measles reported was around 500,000 per 100,000 live births, ranking the first place in the legal reporting of infectious diseases. Popular curve was once every year the peak. Since the widespread use of MV (196 6 ~ 1978), the incidence of measles dropped to 10 0/10 million. The epidemic curve is still a pandemic every other year. In the early stages of implementing planned immunization (1978-1984), the incidence of measles continued to decline, breaking the law of a perennial peak. After 1985, the use of lyophilized MV, immunization program and the national unity, the incidence of measles declined year by year, the incidence in 1999 was 0 5 2/100 000, the lowest level in history. There is no special pattern of measles distribution. The use of MV, the incidence of measles mainly in March to May, mainly to people under 25, showing the phenomenon of the shift to the older age group. The incidence of measles was highest among primary and secondary students in 1997 ~ 1999, accounting for about 40%; followed by scattered children, accounting for 20%. In the future, we should continue to strengthen the construction of cold chain, raise the vaccination rate, conscientiously do the active monitoring and laboratory monitoring of the measles epidemic, isolate the source of infection in time, thoroughly deal with the epidemic and epidemic areas, and carry out intensive immunization against high-risk groups according to the actual conditions, In order to achieve the goal of controlling and eliminating measles
