<h4>
Where does Ebola come from?</h4>
The first known incidents of the Ebola virus
 were in 1976. There were two simultaneous outbreaks in Nzara in Sudan 
and Yambuku in Zaire (now the Democratic Republic of Congo). The name of
 the Ebola river near Yambuku was given to the new epidemic.<br />

Outbreaks have mainly occured in remote villages in Central and West Africa, close to tropical rainforests.<br />

In the current outbreak, which began in March 2014, more than 1,000 
people have died in West Africa, mainly in Guinea, Sierra Leone and 
Liberia.<br />

Ebola is described by the World Health organisation (<span class="caps">WHO</span>) as “one of the most virulent viral diseases known to humankind.”<br />

There are five distinct species of Ebola and the survival rate ranges from 25 to 90%.<br />

There is no licensed vaccine for Ebola although several are currently being tested.<br />

<h4>
How is the Ebola virus transmitted?</h4>
<ul>
<li>Ebola is passed to humans through close contact with the blood or 
bodily fluids of infected animals. Fruit bats, monkeys and chimpanzees 
can all carry the virus.</li>
</ul>
<ul>
<li>Ebola then spreads through human-to-human transmission, again from contact with blood or bodily fluids.</li>
</ul>
<ul>
<li>Burial ceremonies where mourners touch the body of the dead person can also spread the disease.</li>
</ul>
<ul>
<li>The incubation period (the time from infection to the onset of symptoms) is between two to 21 days.</li>
</ul>
<ul>
<li>People remain infectious as long as their blood and secretions contain the virus.</li>
</ul>

<h4>
What are the symptoms?</h4>

Initial symptoms include the sudden onset of a high fever,  muscle pain, general weakness, headache and sore throat. <br />

Further symptoms include vomiting, diarrhoea, rashes, damage to the kidney and liver function.<br />

In some cases symptoms can include both internal and external bleeding. <br />

There is no known cure or vaccine for Ebola. <br />

<h4>
How can the virus be prevented?</h4>
<ul>
<li>Routinely cleaning and disinfecting farms to inactivate the virus.</li>
</ul>
<ul>
<li>Animals should be handled with gloves and  protective clothing. Meat should be thoroughly cooked before eating.</li>
</ul>
<ul>
<li>If an outbreak is suspected in animals, the premises should be quarantined and infected animals culled.</li>
</ul>
<ul>
<li>Avoiding physical contact with people infected with Ebola and protective clothing must be worn.</li>
</ul>
<ul>
<li>Washing hands after visiting patients in hospital, or after taking care of those infected at home.</li>
</ul>
<ul>
<li>Inform the authorities when a community is affected so containment measures can be taken.</li>
</ul>
<ul>
<li>Ebola victims should be buried quickly and safely, with no direct contact with the corpse.</li>
</ul>
<h4>
What is being done to treat it?</h4>
Several vaccines are being tested, but none have been approved for clinical use.<br />

One of the untested drugs, Zmapp, has been used on two American 
missionaries who are said to be improving. It was also given to a 
Spanish priest who later died. Its effectiveness is unknown but the <span class="caps">WHO</span> has ruled its use ethical in the circumstances.<br />

Severely ill patients require intensive supportive care. Patients 
are frequently dehydrated and require oral rehydration with solutions 
containing electrolytes or intravenous fluids.<br />

Stocks of Zmapp, which was developed by an American pharmaceutical 
company, have been sent to West Africa. The company says it has given 
the treatment free of charge.<br />

Canada has also sent around 1000 doses of an experimental drug 
developed by government laboratories. It has previously shown promising 
results in animals but has never been tested on humans.<br />
