London, Dhu-AlQa'dah 17, 1435, Sep 12, 2014, SPA -- Cuba's health ministry said Friday it is sending more than 160 health workers to help stop the raging Ebola outbreak in Sierra Leone. World Health Organization chief Dr. Margaret Chan said the agency was extremely grateful for the help. "If we are going to go to war with Ebola, we need the resources to fight," she said. "This will make a significant difference in Sierra Leone. Human resources are most important," AP quoted Chan as saying, noting a crucial need for experienced doctors and nurses across the region. Ebola is believed to have killed more than 2,200 people in West Africa so far, the biggest-ever outbreak of the lethal virus. So far, the death rate is about 50 percent. Doctors and nurses are at high risk of catching Ebola. --SPA 13:39 LOCAL TIME 10:39 GMT www.spa.gov.sa/w
