A large measles outbreak has been ongoing in Milan and surrounding areas. From 1 March to 30 June 2017, 203 measles cases were laboratory-confirmed (108 sporadic cases and 95 related to 47 clusters). Phylogenetic analysis revealed the co-circulation of two different genotypes, D8 and B3. Both genotypes caused nosocomial clusters in two hospitals. The rapid analysis of epidemiological and phylogenetic data allowed effective surveillance and tracking of transmission pathways.
米兰及周边地区一直在发生大规模麻疹疫情。2017年3月1日至6月30日,有203例麻疹病例经实验室确诊(108例散发病例,95例与47个聚集性病例群有关)。系统发育分析显示两种不同基因型D8和B3共同传播。两种基因型均在两家医院引发了医院内聚集性病例。对流行病学和系统发育数据的快速分析有助于对传播途径进行有效监测和追踪。
