Hello Nairalanders
It is often said that “knowledge is power”. thus I have packaged for us all you need to know about the virus. Please don’t ignore just read, like the page and comment or share. Thanks

(CNN) - It began with a just a handful of cases in Guinea in March. But it spread quickly to two other countries and is now the deadliest outbreak of Ebola virus on record.

At least 759 people in Guinea, Sierra Leone and Liberia have been infected by Ebola since its symptoms were first observed four months ago, according to the World Health Organization. 467 of them have died. That's a 61.5 percent mortality rate.

The WHO says "drastic action is needed" to contain the virus, which has spread from rural areas to cities in West Africa. It has dispatched teams of experts to the region and is holding talks this week with the health ministers from 11 countries about what to do next.

Why does Ebola generate such fear?

Medecins Sans Frontieres (MSF) describes Ebola as "one of the world's most deadly diseases."

"It is a highly infectious virus that can kill up to 90% of the people who catch it, causing terror among infected communities," it says.

There is also no vaccination against it.

Of Ebola's five sub-types, the Zaire strain -- the first to be identified -- is considered the most deadly.

The WHO said preliminary tests on the Ebola virus in Guinea in March suggested that the outbreak there was this strain, although that has not been confirmed.

What is Ebola?

The Ebola virus causes viral hemorrhagic fever (VHF), which according to the U.S. Centers for Disease Control and Prevention (CDC), refers to a group of viruses that affect multiple organ systems in the body and are often accompanied by bleeding.

The virus is named after the Ebola River in the Democratic Republic of Congo (formerly Zaire), where one of the first outbreaks occurred in 1976. The same year there was another outbreak in Sudan.

The WHO says there are five different strains of the virus -- named after the areas they originated in. Three of these have been associated with large outbreaks of hemorrhagic fever in Africa.

These are the Bundibugyo -- an area of Uganda where the virus was discovered in 2007 -- Sudan and Zaire sub-types.

There has been a solitary case of Ivory Coast Ebola. This subtype was discovered when a researcher studying wild chimpanzees became ill in 1994 after an autopsy on one of the animals. The researcher recovered.

Finally, Reston Ebola is named after Reston in the U.S. state of Virginia, where this fifth strain of the Ebola virus was identified in monkeys imported from the Philippines.

The CDC says while humans have been infected with Ebola Reston, there have been no cases of human illness or death from this sub-type.

What are Ebola's symptoms?

Early symptoms of the Ebola virus include sudden onset of fever, weakness, muscle pain, headaches and a sore throat. These symptoms can appear two to 21 days after infection.

The WHO says these non-specific early symptoms can be mistaken for signs of diseases such as malaria, typhoid fever, meningitis or even the plague.

MSF says some patients may also develop a rash, red eyes, hiccups, chest pains and difficulty breathing and swallowing.

The early symptoms progress to vomiting, diarrhea, impaired kidney and liver function and sometimes internal and external bleeding.

Ebola can only be definitively confirmed by five different laboratory tests.

How is it treated?

There are no specific treatments for Ebola. MSF says patients are isolated and then supported by health care workers.

"This consists of hydrating the patient, maintaining their oxygen status and blood pressure and treating them for any complicating infections," it says.

There have been cases of healthcare workers contracting the virus from patients and the World Health Organization has issued guidance for dealing with confirmed or suspected cases of the virus.

Carers are advised to wear impermeable gowns and gloves and to wear facial protection such as goggles or a medical mask to prevent splashes to the nose, mouth and eyes.

MSF says it contained a 2012 outbreak in Uganda by placing a control area around its treatment center. An outbreak is considered over once 42 days -- double the incubation period of the disease -- have passed without any new cases.

How does it spread?

The WHO says it is believed that fruit bats may be the natural host of the Ebola virus in Africa, passing on the virus to other animals.

Humans contract Ebola through contact with the bodily fluids of infected animals.

The WHO says in Africa there have been documented cases of humans falling ill after contact with dead or ill chimpanzees, gorillas, fruit bats, monkeys, forest antelope and porcupines.

It says Ebola later spreads from human-to-human via contact with bodily fluids containing the virus. The virus can be spread through contact with an object contaminated with infected secretions.

Direct contact with the corpses of Ebola victims can also result in infection and the virus can be transmitted via infected semen up to seven weeks after clinical recovery.

MSF says while the virus is believed to be able to survive for some days in liquid outside an infected organism, it is fragile and chlorine disinfection, heat, direct sunlight, soaps and detergents can kill it.

MSF epidemiologist Kamiliny Kalahne says outbreaks usually spread in areas where hospitals have poor infection control and limited access to resources such as running water.

"People who become sick with it almost always know how they got sick: because they looked after someone in their family who was very sick -- who had diarrhea, vomiting and bleeding -- or because they were health staff who had a lot of contact with a sick patient," she says.

How many cases have there been?

The CDC estimates there have been more than 1,800 cases of Ebola and more than 1,300 deaths.

The last recorded outbreaks before the current one in Guinea were in 2012 -- in Uganda and Democratic Republic of Congo.

The Uganda outbreak involved a total of 24 probable and confirmed cases, and 17 deaths, according to the WHO, which declared it had ended in October 2012.

MSF said the Uganda outbreak had been the Sudan strain, while the virus found in DRC was the Bundibugyo sub-type.

According to the CDC, the most deadly outbreak was the 1976 outbreak in then Zaire, when 280 of 318 infected people died. In 2000, there were 425 cases of Ebola Sudan in Uganda, which resulted in 224 fatalities.

If Ebola is so infectious, why hasn't it spread further?

MSF epidemiologist Kamiliny Kalahne says there have not yet been any cases of Ebola being spread to a developed country.

"This is because people generally transmit the infection when they are very sick, have a high fever and a lot of symptoms -- and in these situations, they don't travel.

"And even if they do get sick once they travel to a developed country, they will be in a good hospital with good infection control, so they are very unlikely to infect others," she says.

dont forget the virus has already enterd Nigeria

NIGERIAN DOCCTOR FINDS CURE FOR EBOLA ?

Four out of five people who get infected die

A plant has been found to halt the deadly Ebola virus in its tracks in laboratory tests, scientists have said.
The extract can be eaten or rubbed into the skin
They used a compound from Garcinia kola, a plant commonly eaten in West Africa. Compounds from the plant have also proved effective against some strains of flu.
If the anti-Ebola compound proves successful in animal and human trials, it will be the first medicine to successfully treat the virus that causes Ebola haemorrhagic fever - an often-fatal condition.
The discovery was announced at the 16th International Botanical Congress in St Louis in the US.
Four deaths per five cases
The Ebola virus was first documented in 1976 after an outbreak in Zaire - now the Democratic Republic of the Congo - where 88% of the 318 human cases died.



The Ebola-Zaire virus close up
More recently, a 1995 outbreak in the same country had a death rate of 81% of the 315 infected.
There are four types of the virus - Ebola-Zaire, Ebola-Sudan and Ebola-Ivory Coast all affect humans, while Ebola-Reston has so far only affected monkeys and chimpanzees.
However, doctors have been unable to stop the virus once infection has taken hold - hence the disease has gained a terrifying reputation.
Traditional origins
Dr Maurice Iwu, who set up and heads the Bioresources Development and Conservation Programme, led the research.



Dr Maurice Iwu said the discovery was a breakthrough
It started 10 years ago when researchers were led to the plant by traditional native healers who have used the plant for the treatment of infectious diseases for centuries.
"This is a very exciting discovery," said Dr Iwu, who himself comes originally from a family of traditional healers.
"The same forest that yields the dreaded Ebola virus could be a source of the cure."
Fighting chance
The virus multiplies rapidly in the human body and quickly overwhelms it, and in advanced cases the patient develops high fever and severe bleeding.



Towns are quarantined following an outbreak
The Garcinia kola compound has been shown to halt multiplication of the virus in the laboratory. If repeated in humans, this would give the body a chance to fight off the virus.
The active compound is what is known as a dimeric flavonoid, which is two flavonoid molecules fused together.
Flavonoids are non-toxic and can be found in orange and lemon rinds as well as the colourings of other plants.
Drug hopes
The tests are in the early stages still, but the researchers hope that if they continue to prove successful the compound the US Food and Drug Administration will put it on a fast track - making a drug available to humans within a matter of years.
"The discovery of these important properties in a simple compound - flavonoids - was very surprising," said Dr Iwu.
"The structure of this compound lends itself to modification, so it provides a template for future work.
"Even if this particular drug does not succeed through the whole drug approval process, we can use it to construct a new drug for this deadly disease."
