What is Ebola and why is it so deadly? | archive



(Meredith / CNN) – The ongoing outbreak of Ebola in the Democratic Republic of Congo is "a crucial moment," the World Health Organization said on Friday.

Since the outbreak on August 1 has been declared, 116 people are infected, including 77 deaths. As of Wednesday, 86 of the cases were confirmed by laboratory results and 30 were likely.

But what is Ebola and why is it so deadly?

Ebola facts

Ebola hemorrhagic fever is a disease caused by one of the five different Ebola viruses. Four of the strains can cause serious diseases in humans and animals. The fifth, Reston virus, has caused disease in some animals, but not in humans.

There are five subspecies of the Ebola virus: Zaire Ebola virus (EBOV) Bundibugyo Ebola virus (BDBV) Sudan Ebola virus (SUDV) Taï Forest Ebola virus (TAFV) Reston Ebola virus (RESTV)

Infectious, but not very contagious

Ebola is extremely contagious, but not extremely contagious. It is contagious because an infinitesimal number of diseases can cause. Laboratory experiments on non-human primates suggest that even a single virus may be sufficient to cause a fatal infection.

Ebola can be considered as moderately contagious because the virus is not transmitted by air.

Humans can be infected by other people if they come into contact with body fluids from an infected person or infected objects from infected people. People can also be exposed to the virus, for example by slaughtering infected animals.

Although the exact reservoir of Ebola viruses is still unknown, researchers think that the most likely natural hosts are fruit bats.

What are the symptoms?

Symptoms of Ebola are usually: Weakness Fever Pears Diarrhea Vomiting Gastric pain Rash Red eye Chest pain Sore throat Difficulties with breathing Swallowing Haemorrhage (including internal) Symptoms seem to be eight to ten days after exposure to the virus, but the incubation period may be two to 21 days.

Unprotected healthcare workers are prone to infections because of their close contact with patients during treatment.

How do people get Ebola?

Ebola is not transferable if someone is asymptomatic and usually not after someone has recovered from it. However, the virus was found in sperm for up to three months and "possible" is transmitted by contact with that sperm, according to the CDC.
