All you need to know about the Ebola virus

Infection with this virus begins with the symptoms of a common cold, but escalates to bleeding, pain and irritation.

The first signs that this extremely dangerous virus has entered the body are: high temperature, headache and sore throat. It starts attacking immune cells during this time, leaving the impression of an ordinary cold. As progresses, small blood vessels burst, causing internal and external bleeding.

The virus has an incubation period of between 2 and 21 days and has a death rate of 90 percent.

It is transmitted through contact with the blood of a human or animal already infected, by fluids, organs and sexual intercourse, even after 40 days after a person has healed. When fever and headache are installing, that person is already a source of infection.

In the case of this virus, the immune system turns against the body and in a few days the patient reaches the critical point, where, either recovers or passes in fatal stage. There is no vaccine against this disease and those who survive have to do tests on a regular basis.

World Health Organization (WHO) recommends travel and trade restriction, but the risk for travelers is low because the transmission from person to person is resulting from direct contact with body fluids.
