Recent evidence has confirmed the importance of bats as potential
reservoir species of filoviruses; however, it is unclear whether other
species are also involved or how transmission to humans and/orapes takes place. EHF is believed to persist in a reservoir species
generally found in endemic places. Apes, man, and perhaps other
mammalian species being susceptible to Ebola virus infection are
considered as end hosts of Ebola rather than as reservoir. Although
wide efforts have been made to find the natural reservoirs in large
outbreaks of EHF, neither potential hosts nor arthropod vectors have
been identified. For a long time, rodents and bats have been regarded
as potential reservoir species. This was proved by experimental
studies in African plants and animals that confirmed the transmission
of productive infection of African fruit and insectivorous bats
with ZEBOV, though a firm link could not be achieved[9,12]. The
inspection for potential vectors, especially among arthropods has
been always negative, including bedbugs (Cimex hemipterus)
captured in the beds of infected persons
