Ebola virus is a member of the filovirus family, so-named because it is shaped like a filament. It has been found in Africa and the Philippines. The Filipino strain does not appear to cause disease in humans although, like at least one of the African strains, it is often fatal to monkeys. Pressurized air circulates inside it, reducing the chance that airborne contaminants might contact the body. Experiments are done inside wall niches, called hoods, that also have specialized air-flow systems.
