We assessed the epidemiological characteristics of a mumps virus epidemic (genotype D) that occurred in the Netherlands between August 2007 and May 2009 and its association with a subsequent mumps outbreak in Canada. In the Netherlands, five data sources were used: notifications (only mandatory since the end of 2008) (56 cases), laboratory confirmation data (177 cases), a sentinel general practitioner (GP) database (275 cases), hospitalisation data (29 cases) and weekly virological reports (96 cases). The median age of cases in the notification, laboratory and GP databases ranged from 13 to 15 years. The proportion of cases that were unvaccinated ranged from 65% to 85% in the notification, laboratory and GP databases. Having orthodox Protestant beliefs was the main reason for not being vaccinated. In Canada, a mumps virus strain indistinguishable from the Dutch epidemic strain was detected between February and October 2008 in an orthodox Protestant community with historical and family links to the affected community in the Netherlands, suggesting that spread to Canada had occurred. Prevention and control of vaccine-preventable diseases among population subgroups with low vaccination coverage remains a priority.
我们评估了 2007 年 8 月至 2009 年 5 月期间在荷兰发生的腮腺炎病毒流行（基因型 D）的流行病学特征及其与随后在加拿大发生的腮腺炎暴发的关系。在荷兰，使用了五个数据源：通知（仅在 2008 年底之后强制要求）（56 例）、实验室确诊数据（177 例）、哨点全科医生（GP）数据库（275 例）、住院数据（29 例）和每周病毒学报告（96 例）。通知、实验室和 GP 数据库中病例的中位年龄在 13 至 15 岁之间。通知、实验室和 GP 数据库中未接种疫苗的病例比例在 65%至 85%之间。没有接种疫苗的主要原因是具有正统新教信仰。在加拿大，2008 年 2 月至 10 月期间，在与荷兰受影响社区有历史和家庭联系的正统新教社区中检测到一种与荷兰流行株无法区分的腮腺炎病毒株，表明已经传播到加拿大。在疫苗接种率低的人群亚组中预防和控制疫苗可预防疾病仍然是一个优先事项。
