A study of the incidence and prevalence of multiple sclerosis on the island of Newfoundland between 1960 and 1984 has yielded a current overall prevalence rate of 55.2 per 100,000, but wide variation is noted in the rates for different parts of the island (range, 15.9 to 105.0 per 100,000). The annual incidence rates for St. John's and the Avalon region of Newfoundland show cyclical variation on an approximate five- or six-year cycle. Suggestive evidence for a temporal link between varying incidence rates in these areas and recurrent local outbreaks of canine distemper was obtained.
一项关于1960年至1984年期间纽芬兰岛多发性硬化症发病率和患病率的研究得出，目前总体患病率为每10万人中有55.2例，但该岛不同地区的患病率差异很大（范围为每10万人中有15.9至105.0例）。纽芬兰圣约翰市和阿瓦隆地区的年发病率呈现出大约五到六年的周期性变化。研究获得了一些提示性证据，表明这些地区发病率的变化与犬瘟热的局部反复爆发之间存在时间上的联系。
