The World Health Organization has confirmed that an outbreak of the ebola virus that has killed 70 people in Guinea has spread to Liberia. Two cases of the disease have been reported in the country, and Reuters says that another 11 deaths in Liberia and Sierra Leone — both of which share borders with Guinea — are suspected to be linked to ebola. 
  
 The WHO took seven samples from the Foya district of Liberia, a region less than 12 miles (20 kilometers) from the border with Guinea. The organization said two of those samples tested positive for the ebola virus. The outbreak in Guinea was first reported on March 23rd, when the WHO and Guinea's Ministry of Health acknowledged fatal cases of the ebola virus in south-eastern areas of the country. The disease then spread to Guinea's capital, Conakry, with four suspected cases of the virus confirmed by laboratory analysis. Guinea's Ministry of Health claimed a fatality rate of 63 percent, with 70 deaths from 111 cases of haemorrhagic fever. Ebola appears to have made its way into Liberia more than a week ago: the WHO said that a 35-year-old woman who died on March 21st tested positive for the virus. 
  
 11 deaths in Sierra Leone and Liberia are suspected to be linked to Ebola 
  
 Guinea's neighbors have reacted to quell the spread of the disease. Reuters reports Senegal closed its land border with Guinea on Saturday, and halted the operation of weekly markets in the area. Senegal has also implemented sanitary checks on flights between its capital Dakar and Conakry, while West African airline Gambia Bird has delayed the launch of a new route to Guinea's capital. 
  
 Ebola is spread primarily through contact with infected bodily fluids. It's a highly contagious and regularly lethal disease — 68 percent of all recorded cases in the past have been fatal — that has killed more than 1,500 people since its first recorded transferal to humans in 1976. The confirmed cases in Guinea and Liberia are particularly notable because they are the first to be recorded in the west of the continent — prior to this outbreak, every known case of fatal Ebola infection (excluding laboratory accidents) took place in in south and central Africa. Should the outbreak continue to gather pace, it could stretch West African health providers to the limit. ||||| * Geographical spread of Guinea Ebola outbreak a worry -MSF

 CONAKRY, March 31 Guinea faces an Ebola epidemic on an unprecedented scale as it battles to contain confirmed cases now scattered across several locations that are far apart, medical charity Medecins Sans Frontieres said on Monday. 
  
 The warning from an organisation used to tackling Ebola in Central Africa comes after Guinea's president appealed for calm as the number of deaths linked to an outbreak on the border with Liberia and Sierra Leone hit 80. 
  
 The outbreak of one of the world's most lethal infectious diseases has spooked a number of governments with weak health systems, prompting Senegal to close its border with Guinea and other neighbours to restrict travel and cross-border exchanges. 
  
 Figures released overnight by Guinea's health ministry showed that there had been 78 deaths from 122 cases of suspected Ebola since January, up from 70. Of these, there were 22 laboratory confirmed cases of Ebola, the ministry said. 
  
 "We are facing an epidemic of a magnitude never before seen in terms of the distribution of cases in the country," said Mariano Lugli, coordinator of MSF's project in Conakry. 
  
 The organisation said it had been involved in nearly all other recent Ebola outbreaks, mostly in remote parts of central African nations, but Guinea is now fighting to contain the disease in numerous locations, some of which are hundreds of kilometres apart. 
  
 "This geographical spread is worrisome because it will greatly complicate the tasks of the organisations working to control the epidemic," Lugli added. 
  
 The outbreak of Ebola - which has a fatality rate of up to 90 percent - has centred around Guinea's southeast. But it took authorities six weeks to identify the disease, allowing it to spread over borders and to more populated areas. 
  
 APPEAL FOR CALM 
  
 Cases were last week confirmed in Conakry, bringing the disease - previously limited to remote, lightly-populated areas - to a sprawling seaside capital of two million people. 
  
 Guinea's President Alpa Conde late on Sunday appealed for calm. "My government and I are very worried about this epidemic," he said, ordering Guineans to take strict precautions to avoid the further spread of the disease. 
  
 "I also call on people not to give in to panic or believe the rumours that are fuelling people's fears," he added. 
  
 Liberia has recorded a total of seven suspected and confirmed cases, including four deaths, the World Health Organisation said. Sierra Leone has reported 5 suspected cases, none of which have been confirmed yet. 
  
 Brima Kargbo, Sierra Leone's chief medical officer, said a screening process had been introduced on the country's northern border with Guinea. Travellers are being asked where they are coming from and whether they or anyone they had been in contact with had fallen ill, he said. 
  
 Senegal, another neighbour of Guinea's, closed its land border over the weekend and has suspended weekly markets near the border to prevent the spread of the disease. 
  
 Regional airline Gambia Bird delayed the launch of services to Conakry, due to start on Sunday, because of the outbreak. 
  
 If the deaths are all confirmed as Ebola, a disease that leads to vomiting, diarrhoea and external bleeding, it would be the most deadly epidemic since 187 people died in Luebo, in Congo's Kasai Orientale province, in 2007.

The scale of the Ebola epidemic that has now killed at least 80 people in Guinea is "unprecedented," according to Doctors Without Borders. "We are facing an epidemic of a magnitude never before seen in terms of the distribution of cases in the country," says a coordinator at the medical charity. Cases of the disease are scattered among several distant locations, which will make the epidemic more difficult to control, Reuters reports. As the outbreak grows, Senegal has closed its border with Guinea, and other neighboring countries are restricting travel. The hemorrhagic fever is one of the most lethal infectious diseases in the world, with a fatality rate as high as 90%. The current fatality rate is 63%, the Verge reports. Ebola has recently spread to more populated areas, including Conakry, the country's capital. There are also seven suspected and confirmed cases in Liberia, and five suspected cases in Sierra Leone.
