The prevalence of probable multiple sclerosis in Monreale city, close to the university city of Palermo, Sicily, is at least 43 per 100 000. If the possible multiple sclerosis patient is included, it is 47 per 100 000. This prevalence is not significantly different from that found in Enna city, 53 per 100 000. The prevalence in Sicily and, no doubt, in Italy has, in the past, been seriously underestimated. This confirms the need for thorough studies of small populations if many patients are not to be overlooked in a prevalence survey.
在西西里岛巴勒莫大学城附近的蒙雷阿莱市,可能患有多发性硬化症的患病率至少为每10万人中有43例。若将可能患有多发性硬化症的患者计算在内,则为每10万人中有47例。这一患病率与恩纳市每10万人中有53例的患病率并无显著差异。过去,西西里岛乃至整个意大利的患病率都被严重低估了。这证实了在患病率调查中,若不想遗漏众多患者,就需要对小群体进行全面研究。
