There are seven exotic diseases of concern; three of these, the most unpredictable and least understood, are Lassa fever, Marburg virus disease and Ebola virus disease. In this article the epidemiologic aspects of these diseases are discussed, with particular emphasis on exportation from their indigenous areas in Africa and on the occurrence of secondary cases. Any of these conditions could be brought into Canada either by aeromedical evacuation or inadvertently. Between 1972 and 1978 there were seven occasions when Canada could have been involved with handling cases of Lassa fever. The Government of Canada has purchased several containment bed and transit isolators. These units, with filtered air under negative pressure, accommodate infectious patients being transported and cared for without contaminating medical attendants or the environment.
有七种令人关注的外来疾病；其中三种，即最难以预测且了解最少的疾病，是拉沙热、马尔堡病毒病和埃博拉病毒病。本文讨论了这些疾病的流行病学方面，特别强调了它们从非洲本土地区传出以及二代病例的发生情况。这些疾病中的任何一种都可能通过空中医疗后送或意外传入加拿大。在1972年至1978年期间，加拿大有七次可能涉及处理拉沙热病例的情况。加拿大政府已购买了若干隔离病床和转运隔离器。这些装置通过负压过滤空气，可容纳正在转运和接受护理的传染病患者，而不会污染医护人员或环境。
