Government health workers are seen during the administration of blood tests for the Ebola virus in Kenema, Sierra Leone, June 25, 2014. West African states lack the resources to battle the world’s worst outbreak of Ebola and deep cultural suspicions about the disease remain a big obstacle to halting its spread, ministers said on Wednesday. The outbreak has killed 467 people in Guinea, Liberia and Sierra Leone since February, making it the largest and deadliest ever, according to the World Health Organization (WHO) Picture taken June 25, 2014.
