由于农村自然条件生活条件的特点,往往在麻疹流行前期易感儿童的百分比较高,有的高达90%以上,一旦传染源输入,如果采取防治措施不力,很快波及自然村及邻近的社队大面积暴发流行,合并症多,死亡率高,对儿童健康和生命安全威胁很大。在还没有普遍使用麻疹减毒活疫苗注射免疫以前,如何在易成率较高的情况下,控制大流行,推迟发病年龄;如何在医务力量比较薄弱,医疗技术较差的条件下,防止或控制麻疹流行,减少麻疹合并症,降低病死率,是我们农村医务工作者面临的重要任务。
Due to the nature of living conditions in rural areas, the percentage of susceptible children in the pre-measles epidemic period is often high, some as high as 90% or more. Once the source of infection is imported, poor prevention and control measures quickly affect natural villages and neighboring community teams Outbreaks of area, with more complications, high mortality, a great threat to children’s health and life safety. How to control the pandemic and postpone the onset of the disease at a time when the immunization rate of measles vaccine is not yet universal before the immunization of live attenuated measles vaccine; how to prevent or reduce the incidence of Controlling the epidemic of measles, reducing measles complications and reducing mortality is an important task for rural medical workers in our country.
