aReported location where patient received a “bite.” Although some investigators felt the disease was related to the bite, the patient had traveled widely in Zimbabwe and parts of South Africa and was exposed to wildlife at several locations in Zimbabwe (6).

1Although filovirus taxonomy undergoes frequent revision, we follow nomenclature most recently established by the International Committee of Taxonomy of Viruses in 2002. Filoviruses consist of two genera. The genus Marburgvirus contains one species, Lake Victoria marburgvirus, with several recognized strains, and Ebolavirus contains four species: Ivory Coast ebolavirus, Reston ebolavirus, Sudan ebolavirus, and Zaire ebolavirus. For simplicity, we refer to the viruses using the unitalicized vernacular (e.g., Ebola Zaire). We use “Ebola viruses” to refer in general to members of Ebolavirus and “Marburg viruses” to refer in general to members of Marburgvirus. The diseases caused by filoviruses are termed Ebola hemorrhagic fever (HF; diseases caused by Ebola viruses) and Marburg HF (diseases caused by Marburg viruses).
