The 10 keys of Ebola virus

The Government has launched the repatriation operation from a Spanish aid worker from Mali for possible spread of Ebola. The same sources said that would be an MSF doctor from Navarra who apparently suffered a puncture after treating an infected patient.

1. What is it?

A virus that causes the disease eponymous five varieties: Sudan, Zaire, Reston, Côte d'Ivoire (Ivory Coast) and Bundibugyo, which, Sudan, Zaire and Bundibugyo have been associated with large outbreaks of hemorrhagic fever in Africa.
The virus alters a cell type called "endothelial" lining the inner surface of blood vessels and coagulation. To damage the blood vessels platelets are not able to coagulate, and patients succumb to hemorrhagic shock which results in a very severe loss of blood.

2. Appearance

The Ebola virus was first detected in 1976 in two nearly simultaneous outbreaks occurred in Nzara (Sudan) and Yambuku (DRC). The village where there was the second one is located near the Ebola River, which gives it its name.

3. Outbreaks

So far, the worst episode of Ebola was registered in 2000 in Uganda, where some 170 people from more than 400 infected died.

4. Transmission

The virus is transmitted to humans by wild animals and spread in human populations by direct contact with blood, body fluids or tissues of infected persons.
Although monkeys have been a source of infection for humans, it is considered that the fruit bats of the Pteropodidae family are the natural hosts of the virus.

5. Symptoms

The first symptoms of this disease include sudden high fever, severe weakness and muscle pain, headache and sore throat, followed by vomiting, diarrhea, rash, impaired kidney and liver function and intense internal and external bleeding.

6. Demonstration

The incubation period (interval from infection to onset of symptoms) ranges from 2-21 days, but symptoms usually appear between 5 and 10 days after infection.

7. Diagnosis

Ebola is usually diagnosed by testing urine and saliva. The most common tests, according to the World Health Organization (WHO) explains, are tests: enzyme linked immunosorbent assay (ELISA) antigen detection, neutralization, polymerase chain reaction with reverse transcriptase and virus isolation by cell culture.
Samples of infected patients have enormous biohazard and must be taken under maximum protection.

8. Treatment

You still do not have any specific treatment or vaccine, even if they are testing several experimental vaccines. Outbreaks of Ebola have occurred mainly in remote villages in central and western Africa, near rainforests.

9. Forecast

Ebola hemorrhagic fever is one of the deadliest diseases to humans, with a mortality rate of 25 to 90 percent. The average period from onset of symptoms to death is between 2 and 21 days.

10. Prevention

Several are being tested, but for now there is no vaccine against Ebola.
