Ebola Hemorrhagic Fever: Should we fear another outbreak?

Ebola hemorrhagic fever, also know as Ebola HF, is not a common disease. However, this disease is severe and often fatal in humans and also primates such as monkeys, gorillas, and chimpanzees. Ever since it's initial recognition in 1976, there have been four reported sporadic outbreaks in humans around the world. "The first two, in Zaire and in western Sudan, were large outbreaks that resulted in more than 550 cases and 340 deaths. The third outbreak, in Sudan, was smaller, with 34 cases and 22 deaths" (2). The most recent outbreak was reported only eight years ago in Kikwit, a surrounding area of Bandundu Province, and 316 deaths were reported. In most of these cases the outbreaks were reported in health-care settings, a situation known as amplification, and were caused by poor nursing techniques and usage of unsanitary hospital supplies.

This Ebola virus, named after a river in the Democratic Republic of the Congo, is one of two members of a family of RNA viruses known as Filoviridae (http://web.uct.ac.za/microbiology/ebola/ebomurph.gif). Even though the exact origin of the virus is unknown, evidence tells researchers that the virus is animal borne and is usually maintained in an animal host. Evidence also informs researchers that the animal host is native to Africa. Because the origin of the virus is unknown, the carrier state of the virus is also unknown. Therefore the process in which a human is infected with Ebola virus is also undetermined.

An infected human patient can transmit the virus in several ways, by direct contact with blood or bodily secretions of an infected patient, and by contact with objects such as needles used to treat an infected patient. A transfer of the virus from the host to healthy patients is a process known as nosocomial transmission, and occurs frequently through out the period of...
