Can Marburg virus be sexually transmitted?

Background And Aim: Marburg virus (MARV) is a highly virulent virus of animal origin and the cause of a lethal infection (known as Marburg virus disease [MVD]) with a case-fatality ratio ranging from 24% to 90%. While the potential nonzoonotic routes of virus spread are plausible, the risk is not yet fully determined. Here, we described the ways by which MARV spreads within the human population focusing mainly on the potential of sexual transmission.
