FREETOWN, Sierra Leone (AP) — As a boy, marathon runner Idrissa Kargbo sprinted through the villages of Sierra Leone on errands for his grandmother and later as a coffee courier. Kargbo joined nearly 30,000 volunteers and health care workers who fanned out across the country on Friday to distribute soap and information on how to prevent Ebola, which the World Health Organization says has killed more than 560 people in Sierra Leone and more than 2,600 in the region. Despite the late delivery of some supply kits, officials said Saturday the campaign got off to a smooth start, with little evidence of the resistance that plagued the early Ebola response and still lingers in pockets of the hardest-hit countries: For Kargbo, spreading Ebola awareness was a welcome break from idleness after the outbreak cut off all opportunities for him to train and compete. After it was announced earlier this month, Doctors Without Borders warned it would be "extremely difficult for health workers to accurately identify cases through door-to-door screening." The kits contain bars of soap, cards listing Ebola symptoms, stickers to mark houses visited and a tally sheet to record suspected cases.
