Division into Districts of African Natural Foci Province in the Relation to Filoviridae-associated Fevers

The review presents the following division of the African natural foci province into districts: I. Upper Guinea natural focus region includes the following individual natural foci: I.1. Kazamans; I.2. North Guinea; I.3. Volta; I.4. Adamawa; I.5. São Tome. II. Central Africa: II.1. Southern Guinea; II.2. Katanga; II.3. Congo; II.4. Azande; II.5. Ruwenzori. III. South-Eastern Africa: III.1. Mafungabusi; III.2. Drakensberg; III.3. Comoros; III.4. Madagascar; III.5. Seychelles; III.6. Mascarenes. For each natural focus the article describes the characteristic landscapes and species list of fruit-bats (Chiroptera, Megachiroptera) which are natural reservoir for viruses belonging to Filoviridae family, the types of epidemic outbreaks and the intensity of filovirus circulation. Possible explanations of narrowness of filoviruses areal in comparison with fruit-bats areal in Africa are discussed.
