19世纪末与20世纪初喉部常见慢性病是结核,且治疗多无效。早期肺结核中有5％患喉结核,重度患者中可达37％。20世纪50年代抗生素治疗结核后,喉结核发病率大减。近年报告(Farer,1978)美国按人口计有7％感染结核。由于结核可与其他病情混淆而常误诊给人们带来危险。最近调查(Barrett-Connor,1979)医生的发病率至少是同年龄组群众的两倍,特别是耳鼻喉科手术医师因间接喉镜检查,面对患者张口、咳嗽,有45%接触感染源的机会,居最多接触医
The common chronic disease of the larynx in the late 19th and early 20th century was tuberculosis, and treatment was ineffective. Throat tuberculosis is present in 5% of early tuberculosis, up to 37% in severe patients. After the antibiotic treatment of tuberculosis in the 1950s, the incidence of laryngeal tuberculosis dropped significantly. Recent reports (Farer, 1978) that the United States has 7% of tuberculosis by population. Misdiagnosis is often dangerous to people because tuberculosis can be confused with other conditions. In the most recent survey (Barrett-Connor, 1979), the prevalence of physicians was at least twice that of the same age group, and in particular otolaryngologists were 45% exposed to infection due to indirect laryngoscopy, patient mouth opening and coughing Opportunity, Habitat access to medicine
