Ebola is a deadly virus disease that is transmitted through direct contact with contaminated surfaces or bodily fluids of humans or animals, (“Ebola virus disease,” 2016). It is not entirely known exactly how Ebola works in the body, but scientists have theories, (“What Does Ebola Do to the Body,” 2016). An article by Servick (2014) states that once it has entered the body, the virus attacks the victim’s dendritic cells, which activates the body’s T cells, so the body is unable to fend off the disease. The article notes that the virus is able to replicate itself quickly by intercepting interferons, which are molecules that stop viral reproduction, and potentially kill the victim if left untreated. Victims generally break out into fevers and have body pains in the early stages of infection, (“What Does Ebola Do to the Body,” 2016). Servick (2014) also indicates that next, macrophages, which are a type of white blood cell, eats the virus as it travels through the blood which in turn infects the macrophage and causes clotting in the blood vessels and decreases blood flow to vital parts of the body. She asserts that it also causes the blood vessels to leak because they produce nitric oxide, a gas, which leads to a symptom of some patients externally hemorrhaging and bleeding from certain orifices. Ebola either targets cells in different tissues or it signals for immune cells to release inflammatory molecules which also destroy cells, as mentioned in Servick’s article.…
