Ebola hemorrahagic fever is a 20 year old virus that, with a mortality rate of 50% to 90%, is one of the world's deadliest viruses. Its causative organism is called Ebola virus. Ebola virus is a member of filoviridae, a family of negative-strained RNA viruses. The filoviridae family consists of five known members, Marburg, Ebola Zaire, Ebola Sudan, Ebola Reston, and Ebola
Tai.
Ebola virus is spread in a number of ways. An outbreak starts when an infected animal or insect, called a vector, transmits the virus to a human.
Scientists know that monkeys are both a vector and victim of Ebola, but other vectors are unknown. The natural reservoir for the virus, or organism that is immune to it and carries it is also unknown. A search …show more content…
There is currently no cure or vaccine for the Ebola virus., although it is recorded that someone in the United Kingdom was infected with
Ebola Zaire and was injected with the plasma of a recovered Ebola Zaire victim and recovered fully. The opposite was also shown when recovered Ebola Reston monkeys were infected with Ebola Zaire and died faster than monkeys infected with just the Ebola Zaire strain. Therefore, it is thought that plasma injections only work on common strain victims. The first occurrence of the Ebola virus was discovered in July of 1979 near the Ebola River in Northern Zaire after a worker in a cotton factory in
Nzara, Sudan became very ill. Later that year a similar virus spread through more than 50 villages along the river in Zaire. This outbreak caused about 500 deaths. Scientists from the CDC in Atlanta named the new virus Ebola, subtype
Zaire. The virus that caused the outbreak in Sudan was later called Ebola Sudan. In 1977 a child in Tandala, Zaire died of a hemorrahagic fever. In 1977 another outbreak occurred in Sudan and the first case was pinpointed to the same room in the cotton factory that the victim in 1979 had worked in. In 1989 another strain of Ebola was found in Reston, Virginia.
