Hepatitis A Strain Linked to the European Outbreaks During Gay Events between 2016 and 2017, Identified in a Brazilian Homosexual Couple in 2017

Viruses. 2019 Mar 20;11(3):281. doi: 10.3390/v11030281.


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.

Keywords: European strain; HAV in Brazilian MSM; Hepatitis A virus (HAV).
