Another large outbreak of mumps occurred in Lothian from October 2017, which coincided with the commencement of the higher education term. During this period 324 cases were notified, most of whom were aged 18-22 years old. Although previous outbreaks had a focus in student populations, 43% of current cases reported that they were not a student. There has been increases in private student housing where students from all universities live, which may have contributed to the wide spread of the outbreak and complicated outbreak control. Information on vaccination status was available for 244 cases (75%), of whom the majority (75.8%) reported having two MMR doses. To investigate potential waning vaccine immunity the mean length of time since last mumps containing vaccine was calculated as 14.3 years. The outbreak was declared over in May 2018 after case numbers returned to background levels. This outbreak highlighted that mumps outbreaks occur cyclically coinciding with new cohorts of susceptible students entering the Lothian population. The lessons from this outbreak are to encourage students to have two MMR doses and also be prepared for mumps outbreaks in the near future. In future outbreaks the utility of a third MMR for outbreak control could be examined.
2017 年 10 月,洛锡安区又爆发了一场大规模的腮腺炎疫情,恰逢高等教育学期开始。在此期间,共报告了 324 例病例,其中大多数年龄在 18-22 岁之间。尽管以前的疫情主要集中在学生群体中,但目前报告的病例中有 43%的人不是学生。私人学生宿舍的数量有所增加,所有大学的学生都住在那里,这可能导致了疫情的广泛传播和疫情控制的复杂化。有 244 例(75%)病例可提供疫苗接种情况信息,其中大多数(75.8%)报告接种了两剂 MMR 疫苗。为了调查潜在的疫苗免疫力下降,计算了距最后一次含腮腺炎疫苗接种的平均时间为 14.3 年。2018 年 5 月,病例数恢复到背景水平后,疫情宣布结束。此次疫情表明,腮腺炎疫情呈周期性爆发,与新的易感学生群体进入洛锡安区人口有关。此次疫情的教训是鼓励学生接种两剂 MMR 疫苗,并为未来的腮腺炎疫情做好准备。在未来的疫情中,可以研究使用第三剂 MMR 疫苗来控制疫情。
