Produced by the National Institute of Allergy and Infectious Diseases (NIAID), under a magnification of 25,000X, this digitally-colorized scanning electron microscopic (SEM) image depicts numerous filamentous Ebola virus particles (blue) budding from a chronically-infected VERO E6 cell (yellow-green).
Ebola is one of numerous Viral Hemorrhagic Fevers. It is a severe, often fatal disease in humans and nonhuman primates (such as monkeys, gorillas, and chimpanzees).
Ebola is caused by infection with a virus of the family Filoviridae, genus Ebolavirus. When infection occurs, symptoms usually begin abruptly. The first Ebolavirus species was discovered in 1976 in what is now the Democratic Republic of the Congo near the Ebola River. Since then, outbreaks have appeared sporadically.
