Marburg virus disease (MVD) is a rare but severe hemorrhagic fever that affects humans and non-human primates. MVD is caused by Marburg virus, a genetically distinct virus Zoonotic (or animal-borne) RNA viruses Filovirus Filovirus life cycle begins with virus particles attached to Specific cell surface receptors, followed by fusion of the virion envelope with the cell membrane, and release of the viral nucleocapsid into the cytoplasm. https://en.wikipedia.org › Wiki › Filoviridae
