Definition

A family of RNA viruses, including Ebola and Marburg, known for causing severe and often fatal hemorrhagic fever in humans and non-human primates.

Etymology

The term is derived from the Latin 'filum' (meaning 'thread') and the Latin 'virus' (meaning 'poison' or 'venom'), referring to the distinct, thread-like physical structure of these viruses when viewed under a microscope.
