Ebola, one of the world's most deadly viruses, has spread from a remote forested corner of southern Guinea to the country's seaside capital, raising fears that the disease, which causes severe bleeding and almost always death, could spread far beyond this tiny West African nation's borders.
In the first outbreak of its kind here, Ebola already has killed at least 70 people including one man whose family brought him to Conakry, the capital, for medical treatment. Now six of his relatives and two others exposed to him are being kept in isolation at a hospital.
Health officials warn that the arrival of Ebola in this sprawling city of some 2 million people with an international airport could spell disaster. Among the poorest countries in the world, Guinea has severely limited medical facilities and a large population living in slums where the virus could spread quickly.
"Poor living conditions and lack of water and sanitation in most parts of Conakry poses a serious risk of this epidemic spiraling into a crisis," said Ibrahima Toure, country director for the aid group Plan International.
Panic already has grown among residents since the government announced the Conakry cases late Thursday on national television. While most days up to 300 patients seek treatment at Donka Hospital, less than 100 came on Friday as news spread that the Ebola patients were being quarantined there.
"My daughter is sick and coughing but I prefer to keep her at home. I wouldn't set foot inside Donka Hospital for anything in the world right now," said Djalikatou Balde, a teacher.
International aid groups like Doctors Without Borders and Plan International are trying to educate Guineans about how the disease is spread, and working to identify and isolate anyone who may have been exposed. There is no cure for the disease and the virus strain in Guinea has a fatality rate of up to 90 percent. Some 111 people have fallen ill already and authorities in neighboring Liberia and Sierra Leone are also investigating suspected cases.
Medical teams have been traveling on foot to villages where cases have been reported. The number of people possibly contaminated expanded exponentially when the Conakry patient traveled some 300 miles across the country in search of help.
The Ebola virus causes severe hemorrhagic fever in patients, in some cases leading to grisly deaths as patients bleed both internally and externally. Its initial symptoms— high fever, headache and weakness—an mimic malaria.
Joseph Gbaka Sandouno, a program unit manager with Plan International in the village of Gueckedou, said it's been especially difficult for people to stay calm after having witnessed "frightening scenes where people have died with severe bleeding."
