Hepatitis A virus (HAV) outbreaks among men who have sex with men (MSM) have been reported worldwide and associated primarily with sexual transmission through oral-anal sex. Here, we provide the molecular and evolutionary description of a European strain, linked to HAV outbreaks among MSM, detected in a Brazilian homosexual couple. Bayesian analysis provided evidence that the viral isolates were introduced in Brazil from Spain between the end of 2016 and the beginning of 2017.
甲型肝炎病毒(HAV)在男男性行为者(MSM)中的爆发已在全球范围内报道,主要与通过肛交的性传播有关。在这里,我们提供了与 MSM 中的 HAV 爆发相关的欧洲毒株的分子和进化描述,该毒株在巴西的一对同性恋者中被检测到。贝叶斯分析提供了证据表明,病毒分离株是在 2016 年底至 2017 年初从西班牙传入巴西的。
