Ebola - disease and dissemination

The Ebola fever is native to West Africa and ensures epidemics with many deaths.

The haemorrhagic fever at a glance

Ebola is a member of the virus-induced haemorrhagic fever. The virus-induced haemorrhagic fever, as the name suggests, transmitted by viruses. They are extremely dangerous because they lead in many cases to death - even under intensive care. In addition, they are highly contagious. At diseases of this group an immediate, massive intervention is essential. It consists only of suspected hemorrhagic fever, individuals must be immediately isolated and intensive care. The disease is not only lethal in most cases, but also highly contagious. The group of virus-induced haemorrhagic fever in addition to the Ebola fever include the Hanta fever, Lassa fever and Marburg fever. In addition, you can expect to dengue fever and yellow fever.

  • The Marburg fever is also from West Africa, but occurred in humans for the first time in 1967 in a Marbuger laboratory. Intermediaries were imported from Uganda Affen.In West Africa there are people with antibodies to the virus. 25 percent of patients die.
  • The Hanta fever occurs mainly in East Asia before, but also in Europe mostly in a milder form. The mild form, epidemic nephropathy, has a mortality rate of only one percent, while the classic form of Hanta fever shows a mortality rate of up to 25 percent. If the lung affected die even 60 percent.
  • The Lassa fever is common in West Africa. Most cases are very mild or no symptoms. Cancels the disease but from threatening circulatory failure and renal failure.

Ebola, the most dangerous hemorrhagic fever

The pathogen is simply called Ebola virus. It is a virus from the group of filoviruses, including Marburg virus belongs, which causes the Marburg fever.

  • Where the pathogen comes at a Ebola epidemic, is not certain. He was often seen in monkeys. The virus is transmitted from person to person through close contact and body fluids. It is extremely anstreckend. Poor hygienic conditions favor the spread. Ebola does in front of anyone, not caring if young or old, man or woman.
  • The disease is difficult and is fatal in 50 to 90 percent. Sufferers first have a high fever with headache and body aches, diarrhea and vomiting. People feel extremely miserable. After a few days to begin the haemorrhage, thus the bleeding. It comes to Hauteinblutungen that create a rash and intestinal bleeding. The liver cells may die (hepatocellular necrosis). The people bleed to death and suffer from dehydration (dehydration) and severe drowsiness. They usually die in a coma.
  • Ebola is hardly attend with modern medicine. Is it only came to destroy the blood vessels, and the medicine is powerless and can only be treated symptomatically. With early treatment, ie before the bleeding, even success can be achieved.
  • Best intensive care and a robust health may give a chance of survival with Ebola. There is also research on a drug that has not yet been approved.
  • The virus runs but so rapidly fatal that the epidemic collapses itself within a short time. People are dying before they can continue to carry the virus.

Ebola epidemics in historical summary

Since spring 2014 rages the heaviest Ebola epidemic in West Africa, from Guinea. The countries of Sierra Leone, Liberia, Nigeria and Senegal are affected. The epidemic is by far demanded by their halt most of the dead. But it is not the first Ebola epidemic.

  • The first epidemic of Ebola fever broke 1976 in Zaire (now Demorkratische Republic of the Congo) from. 280 people died of the epidemic. In the same year there were in Sudan to an epidemic with 151 dead.
  • Until 1995 there was in West Africa (Zaire, Sudan, Gabon) and the East African Uganda repeatedly smaller epidemics with fewer than 100 dead. In addition, the virus arrived in Europe, in the USA and the Philippines, but was detected only in monkeys. There were a few asymptomatic infections in the UK, the US and the Philippines.
  • In 1995 came the next major epidemic with 254 deaths in the DRC. After a few cases, the next major epidemic followed with 425 deaths 2000/2001 in Uganda.
  • There were other smaller epidemics with fewer than 100 dead and two epidemics 2007 in the DRC, with 167, and 187 deaths. 2004 also came to a death in Russia by a laboratory accident.
  • The epidemic of 2014 is by far the worst epidemic in history. The WHO has therefore launched an international health emergency in August, 2014.

Ebola is one of the fastest and safest killing infectious disease of all time. The tragedy: Even those who survived the disease is often socially isolated. The fear of contagion is just too big.
