Ebola viruses. Coloured transmission electron micrograph (TEM) of Ebola viruses, the cause of Ebola fever. These filoviruses are elongated and often, as here, are looped at one end. The disease can be contracted by handling material from infected African green monkeys, but sometimes there is no obvious cause. A number of major outbreaks of Ebola have occurred in equatorial Africa since 1976, causing severe and often fatal symptoms. These include high fever, haemorrhaging and central nervous system damage. There is no absolute cure for the disease, but if excellent supportive therapy is given, most victims recover. Magnification: x7,250 at 5x7cm size.
