一、引言麻疹系一种急性传染发疹疾患,据文献所载主要见于小儿,如Г.А.Ивашенцов等氏认为主要以5岁以前之发病率为最高,可视为儿童传染病;Rosenen氏谓97%之患者为15岁以下者;我国杨思源、王惠芬两氏统计之1216例麻疹患者中10—20岁者占0.3%,20岁以上者为0.4%。另一般均以为患本病后即可获得终身免疫,因而成人麻疹常被忽视。尽管本病在近十余年来由于早期发现以及应用化学、抗生疗法以预防合并症等措施,其死亡率已甚低,如Г.А.Ивашенцов等氏统计为0.3—
I. INTRODUCTION Measles is an acute contagious eruption disease which is mainly found in children’s literature. For example, Г.А.Ивашенцов et al. Think that the incidence of measles is the highest among children before the age of 5 and can be regarded as childhood infectious diseases. Rosenen’s That 97% of patients are under 15 years old; China Yang Siyuan, Wang Huifen two statistics of 1216 cases of measles patients 10-20 years accounted for 0.3%, 0.4% over the age of 20. Others generally think that the disease can get lifelong immunity, which is often overlooked adult measles. Although the disease in the past decade as a result of early detection and application of chemistry, antibiotic therapy to prevent complications and other measures, the mortality rate has been very low, such as Г.А. Ивашенцов et al statistics of 0.3-
