The Ebola Virus Disease has a mortality rate of 90% of those infected. When a person contracts Ebola virus, they start with an Ebola hemorrhagic fever that causes damage to the endothelial cells, which line the blood vessels. In turn, the blood is not able to coagulate properly, thus damaging the walls even more. Ultimately, the person will suffer from hypovolemic shock, which means a traumatic decrease in the blood pressure. If not given medical attention immediately upon showing signs, the hypovolemic shock can result in death. Even those who receive medical attention are still battling against the odds to survive. This article explains in detail ebola virus strains as well as ebola virus mutation which makes it more dangerous.
How Many Ebola Virus Strains Are There?
Ebolavirus is a part of the virus family Filoviridae, and often the members of this virus family are fatal in people and nonhuman primates. Ebola viruses cause Ebolavirus Disease (EVD), which is an illness that causes high fevers, rashes, vomiting, diarrhea, and hemorrhaging. Ebola virus gets its name from the Ebola River, located in Central Africa, and is a part of the Congo River. In 2014, the most devastating outbreak of Ebola occurred in west Africa.
The Ebola stains are often named after the area in which the strain was found in Africa. There five identified strains or species of ebolavirus are:
Zaire Ebolavirus (EBOV)
Sudan Ebolavirus (SUDV)
Tai Forest Ebolavirus (TAFV)
Reston Ebolavirus (RESTV)
Out of these different ebola virus species, the mostly commonly seen in humans is Zaire, Sudan and Bundibugyo Ebola Virus. Among the five ebola virus strains, Reston Ebolavirus only affects non-humans. The types of Ebola strains that are listed may not be the only types of strands that can be found. As the Ebolavirus mutates, new strands combine with one another and ultimately become a new strand of the virus.
Scientists have yet to confirm what type of animal is the host for Ebola, however, the majority of the scientific community seems to believe that the fruit bat is the main carrier.
