There were 688 reported cases of measles in Winnipeg from January to June 1973. Seventy-three cases (10.6%) occurred among previously immunized children, 59% of whom had received their inoculations at less than 1 year of age. Seventy-five cases (10.9%) were severe enough to require admission to hospital, and 92% of these patients developed complications, most often pneumonia. Since 89.4% of the cases occurred among nonvaccinated children and another 6.3% were due to immunization at less than 1 year of age, the nonuse and misuse of measles vaccine appear to be the major causes of the present epidemic.
1973年1月至6月期间，温尼伯市共报告了688例麻疹病例。73例（10.6%）发生在之前已接种疫苗的儿童中，其中59%在1岁以下接种了疫苗。75例（10.9%）病情严重到需要住院治疗，这些患者中有92%出现了并发症，最常见的是肺炎。由于89.4%的病例发生在未接种疫苗的儿童中，另有6.3%是由于1岁以下接种疫苗导致的，麻疹疫苗的未使用和误用似乎是当前疫情的主要原因。
