分析一起发生在中学生的麻疹暴发流行,症状轻、病程短、不典型,既非儿童麻疹亦非成人麻疹为其特点。认为原因是患者接种麻疹疫苗后获得的免疫力下降乃至消失。建议应对中学生进行血清学筛选,对阴性者再次接种疫苗,以阻止麻疹发病年龄后移现状的发生。
The outbreak of measles that occurred in secondary school students was analyzed with mild symptoms, short course of disease and no typical measles. It was neither measles nor adult measles. The reason is that the immunity acquired by the patients after measles vaccination is reduced or even disappeared. It is suggested that serological screening should be conducted for middle school students and vaccination should be conducted again for the negative ones so as to prevent the recurrence of measles age.
