The number of immigrants to Canada from countries where malaria is endemic increased sevenfold between 1964 and 1974. From January 1973 through July 1975, 15 cases of malaria were treated at the Hospital for Sick Children, Toronto. The only symptom common to all patients was fever, and it was not always cyclic. For any child with a fever of unknown cause who has been in a region where malaria is endemic within the previous 6 months, a blood smear should be examined for parasites. If the smear is negative even when stained with acridine orange, serologic testing should be performed. Acurrate species identification is important since therapy varies according to the causative organism.
1964年至1974年间，来自疟疾流行国家的加拿大移民数量增长了七倍。1973年1月至1975年7月，多伦多病童医院共治疗了15例疟疾患者。所有患者唯一的共同症状是发热，且并非总是呈周期性。对于任何在过去6个月内曾身处疟疾流行地区且病因不明发热的儿童，都应检查血涂片以查找寄生虫。即便用吖啶橙染色后涂片仍为阴性，也应进行血清学检测。准确的物种鉴定很重要，因为治疗方法会因致病生物体的不同而有所差异。
