A family of RNA viruses, of the order MONONEGAVIRALES, containing filamentous virions. Although they resemble RHABDOVIRIDAE in possessing helical nucleocapsids, Filoviridae differ in the length and degree of branching in their virions. There are two genera: EBOLAVIRUS and MARBURGVIRUS.

An RNA virus infection of rhesus, vervet, and squirrel monkeys transmissible to man.

A genus in the family FILOVIRIDAE consisting of one species (Lake Victoria marburgvirus) with several strains. The genus shows no antigenic cross-reactivity with EBOLAVIRUS.

A genus in the family FILOVIRIDAE consisting of several distinct species of Ebolavirus, each containing separate strains. These viruses cause outbreaks of a contagious, hemorrhagic disease (HEMORRHAGIC FEVER, EBOLA) in humans, usually with high mortality.

A highly fatal, acute hemorrhagic fever, clinically very similar to MARBURG VIRUS DISEASE, caused by EBOLAVIRUS, first occurring in the Sudan and adjacent northwestern (what was then) Zaire.

Infections with viruses of the family FILOVIRIDAE. The infections in humans consist of a variety of clinically similar viral hemorrhagic fevers but the natural reservoir host is unknown.
