Filovirus virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The exact transmission mode from the natural virus reservoir to a host(nonhuman primate)is unknown. However, animal-to-person and person-to-person transmission occurs via direct contact of infected bodily fluids or contaminated materials. Hemorrhagic fever, organ failure and internal/ external bleeding are the clinical signs in humans and nonhuman primates.
