The deadly Ebola virus has continued to spread in West Africa, where it has killed more than 100 people, health authorities said Tuesday. In Guinea, where the outbreak started, 95 people have died since February, while 151 others are infected with the virus, for which there is neither a vaccine nor cure, dpa quoted health officials as saying on local radio. Some eight people have reportedly recovered from the disease, which has a fatality rate of up to 90 percent, according to the World Health Organization (WHO). The Ebola virus also spread to neighboring Liberia - where 10 people died from the disease, and 21 have been infected - as well as Mali and Sierra Leone, where there are six and two suspected cases respectively. Ebola is one of the most contagious viral diseases known and is transmitted through blood, bodily fluids or close contact with infected people. Ebola's symptoms are extraordinarily painful and include severe vomiting, diarrhoea, fever, impaired kidney and liver function as well as internal and external bleeding.
