Abstract

An outbreak of hepatitis A is ongoing in Portugal, with 71 confirmed cases from 7 October 2023 to 24 April 2024. Most cases are male, aged 18-44 years, with many identifying as men who have sex with men (MSM) and reported as suspected sexual transmission. Phylogenetic analysis identified the subgenotype IA, VRD 521-2016 strain, last observed in an MSM-associated multi-country outbreak in 2016 to 2018. We wish to alert colleagues in other countries to investigate potential similar spread.

摘要

葡萄牙正在爆发甲型肝炎疫情，自 2023 年 10 月 7 日至 2024 年 4 月 24 日，已确诊 71 例病例。大多数病例为男性，年龄在 18-44 岁之间，许多人被认为是男男性行为者（MSM），并报告为疑似性传播。系统进化分析确定为亚基因型 IA，VRD 521-2016 株，最后一次在 2016 年至 2018 年 MSM 相关多国暴发中观察到。我们希望提醒其他国家的同事调查潜在的类似传播情况。
