Diagnosis

What happened & Why?

Ebola is difficult to diagnose because many of the early signs and symptoms resemble those of other infectious diseases, such as typhoid and malaria. But if doctors suspect that you have been exposed to Ebola virus, they use laboratory tests that can identify the viruses within a few days.

Ebola hemorrhagic fever (EHF), caused by Ebola Zaire, Ebola Sudan and Ebola Cote d'Ivoire, "is often characterized by the sudden onset of fever, weakness, muscle pain, headache and sore throat. This is followed by vomiting, diarrhoea, rash, limited kidney and liver functions, and both internal and external bleeding. Blood begins to leak from every opening in the infected primate's body during the last stages of Ebola hemorrhagic fever.

The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission.Fruit bats of the Pteropodidae family are considered to be the natural host of the Ebola virus.Ebola is introduced into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals.

Symptoms:Sudden onset of fever, intense weakness, muscle pain, headache and sore throat. This is followed by vomiting, diarrhoea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding. Laboratory findings include low white blood cell and platelet counts and elevated liver enzymes.

Transmission

The human immune system can normally recognize infected cells and target them for destruction. Many viruses can partially protect their host cells from the immune system, but it seems that Ebola is particularly adept at this behavior, by a largely unknown mechanism.What's known so far is that the Ebola virus encodes for two glycoproteins, one of which disrupts cell attachment. Experiments suggest that Ebola-infected cells display fewer proteins on the cell surface that are critical for immune recognition; the identity of the repressed proteins depends on the type of infected cell.

Ebola first appeared in 1976 in 2 simultaneous outbreaks, in Nzara, Sudan, and in Yambuku, Democratic Republic of Congo. The latter was in a village situated near the Ebola River, from which the disease takes its name.
