麻疹係一種傳染力極强的濾過性毒疾病,以童年期發病者最多,15歲以內患過麻疹的佔97%;每在秋末冬初開始流行,到冬末春初最為猖獗。雖然這是一種盡人皆知的普通流行病,但因其死亡率較低,没有引起衛生工作者足够的重視。事實上這是流行病中發病数較高的疾病,以東北地區而論,1949年傳染病發生死亡統計中,麻疹發病数為89,427例,死亡人數達13,046人,佔各種傳染病罹病死亡率的首位。所以痲疹之流行,雖然沒有霍亂與鼠疫流行之可怖,但不能下認為嚴重的問题。麻疹為兒時的流行病,即因呈露傳染較易,而一次患病後又多能獲得免疫力,因此成人的發病數較低,而第二次患麻疹者又更屬少見,今 Measles is a highly contagious viral disease, with the highest incidence of childhood, measles accounted for 97% of the patients within 15 years of age; each late autumn and winter beginning of the epidemic, the most rampant late winter and early spring. Although this is a well-known pandemic, its low mortality rates have not given enough attention to health workers. In fact, this is a disease with a relatively high number of epidemics. In the northeastern region, the incidence of measles in 1949 was 89,427 and the number of deaths was 13,046, accounting for the morbidity and mortality of various infectious diseases first place. Therefore, the prevalence of measles, although not cholera epidemic epidemic, but can not be considered as a serious problem.

As a result, the number of adults is relatively low, and the second case of measles is even more rare. Today
