Understanding how the ebola virus works in the body

Many drug companies are developing vaccines, although none of these vaccines is ready for full-scale production, or even approved for human treatment [6].

The virus progresses so quickly that researchers have struggled to tease out the precise sequence of events, particularly in the midst of an outbreak. During this period, used condoms should be handled safely, and safely disposed of, so as to prevent contact with seminal fluids.

Etiology of ebola virus disease

Once inside the cells, one of the proteins made by the virus is called Ebola virus glycoprotein [4]. Samples collected from patients are an extreme biohazard risk; laboratory testing on non-inactivated samples should be conducted under maximum biological containment conditions. Epidemiological modelling studies have shown that Ebola virus is about as infectious as influenza or very slightly more so — each infected person will probably infect two to four others. Unlike animals and plants, which also use DNA as a repository of information, viruses are not technically alive because they are incapable of replicating without help. In the 24 Ebola virus outbreaks prior to the present one, a cumulative total of 1, people, two-thirds of all cases, have died. How does this cell-by-cell infection translate to the full-body symptoms of Ebola? Ilana Kelsey is a student in the Biological and Biomedical Sciences graduate program. Here are some of the basic things we understand about how Ebola and humans interact. Laboratory workers are also at risk. Your body aches all over, you have chronic abdominal pain, the fever intensifies and you start to vomit and develop diarrhoea.

In the immediate future, the major challenges in bringing this epidemic under control will continue to be a focus on its containment, coupled with an influx of health-care facilities and experts capable of delivering the best care possible in onerous conditions.

This document provides overall guidance for control of Ebola and Marburg virus outbreaks: When an outbreak is detected WHO responds by supporting community engagement, disease detection, contact tracing, vaccination, case management, laboratory services, infection control, logistics, and training and assistance with safe and dignified burial practices.

While some virus particles are shaped like spheres, the particles that make up Ebola are filament-like in structure, giving them more surface area to potentially attack a greater number of cells. How does the Ebola virus infect people? Controlling infection in health-care settings Health-care workers should always take standard precautions when caring for patients, regardless of their presumed diagnosis.

Ebola triggers a system-wide inflammation and fever and can also damage many types of tissues in the body, either by prompting immune cells such as macrophages to release inflammatory molecules or by direct damage: invading the cells and consuming them from within.

Ebola virus contains a type of genetic material called RNA, which is similar to DNA and contains the blueprint for assembling new virus particles.
