The family Filoviridae is the taxonomic home of several related viruses that form filamentous virions. Two members of the family that are commonly known are Ebola virus and Marburg virus. Both viruses, and some of their lesser known relatives, cause severe disease in humans and nonhuman primates in the form of viral hemorrhagic fevers. All accepted members of the family (all ebolaviruses and marburgviruses) are Select Agents,World Health Organization Risk Group 4 Pathogens (requiring Biosafety Level 4-equivalent containment),National Institutes of Health/National Institute of Allergy and Infectious Diseases Category A Priority Pathogens,Centers for Disease Control and Prevention Category A Bioterrorism Agents, and listed as Biological Agents for Export Control by the Australia Group. It is expected that "cuevaviruses", suggested to be additional members of the family, will be classified in a similar way in the near future.

The family Filoviridae is a virological taxon (i.e. a man-made concept) that was created in 1982 and emended in 1991, 1995, 2000, 2005, 2010 and 2011. The family currently includes the three virus genera "Cuevavirus", Ebolavirus, and Marburgvirus and is included in the order Mononegavirales. The members of the family (i.e. the actual physical entities) are called filoviruses or filovirids. The name Filoviridae is derived from the Latin noun filum (alluding to the filamentous morphology of filovirions) and the taxonomic suffix -viridae (which denotes a virus family).

Stephen Joseph "Steve" Scalise (born October 6, 1965) is the U.S. Representative for Louisiana's 1st congressional district, serving since 2008. He is a member of the Republican Party. He previously served in the Louisiana Senate and the Louisiana House of Representatives.

Scalise graduated from the Catholic Archbishop Rummel High School in Metairie in Jefferson Parish and earned a bachelor of science degree from Louisiana State University in Baton Rouge, with a major in computer programming and a minor in political science. While at Louisiana State University Representative Scalise was initiated as a member of the Acacia Fraternity.

Scalise was elected three times to the Louisiana House of Representatives: 1995, 1999, and 2003. His legislative peers named him to the House Appropriations Committee as the representative of the First Congressional District. Scalise initially succeeded fellow Republican Representative Quentin D. Dastugue, who made an ill-fated bid for governor in the 1995 primary. Scalise opposed the 2002 Stelly Plan, a proposal by Lake Charles Representative Vic Stelly to reduce certain state sales taxes on food for home consumption and utilities in exchange for higher state income taxes.
