本文研究了甘肃省１９５９～１９８８年发生的２３起６３例人间鼠疫的流行病学特征。研究结果表明本省人间鼠疫在地理分布上具有分散性、孤立性、局限性和与鼠疫疫源地的关联性；在时间分布上具有间断性、突发性、不均衡性和集中于狩猎旱獭期的季节性；传染源主要是染疫的喜马拉雅旱獭（Ｍａｒｍｏｔａｈｉｍａｌａｙａｎａ）和肺型鼠疫病人，死于鼠疫的患者尸体和其他染疫动物尸体可能起到过传染源的作用；传播途径以直接接触传染源为主，首发病例均有接触动物史，经飞沫传播次之；人群对鼠疫普遍易感，腺鼠疫和败血症的发生频率高，总病死率为６０．３１％，病例数以农民居多。基于研究掌握的流行特征，提出实施了切实可行的防治措施，人间鼠疫的发生从１９６３年后明显下降，１９８９年至今再未发生人间鼠疫。
This article studies the epidemiological characteristics of 23 human plague cases in 23 cases in Gansu Province from 1959 to 1988. The results show that the human plague in our province has the geographical distribution of dispersibility, isolation, limitations and the relevance of the plague foci; in the time distribution of intermittent, sudden, uneven and concentrated in hunting marmot ; The source of the infection is mainly the infected Marmotahimalayana and the patients with pulmonary plague. The dead bodies of plague patients and other corpse of infected animals may play a role as the source of infection. The route of transmission is direct contact with the source of infection Mainly the first case of contact with animal history, followed by the droplets spread; the crowd is generally susceptible to plague, bubonic plague and sepsis frequency of occurrence, the total case fatality rate was 60.31%, the majority of cases to farmers. Based on the prevailing epidemiological features of the study, it put forward practical prevention and control measures. The occurrence of plague in the world decreased significantly after 1963, and no human plague occurred in 1989.
