High-yield clue

Long, thread-like (filamentous) filovirus; fruit bats are the presumed reservoir and person-to-person spread is via direct contact with body fluids.

Overview

A negative-sense single-stranded RNA filovirus (genus Orthoebolavirus) with a distinctive filamentous shape, studied as a classic cause of viral hemorrhagic fever with a fruit-bat reservoir.
