Millions of dollars are unaccounted for in Ebola response, officials say. This is what we know.

DAKAR, Senegal (AP) — Africa's top public health agency and Congolese officials have raised concerns over $700 million in Ebola aid which is unaccounted for, and called on aid groups to provide more information about their finances.This comes as the world's fastest-growing Ebola outbreak on record continues to outpace efforts, and the virus has spread into eight provinces in Congo and into neighboring countries, Kenya and Uganda.The revelations renew long-standing questions about transparency and accountability in Congo, a country battered by decades of major epidemics, including repeated Ebola outbreaks. In recent months, the AP reported extensively on strikes of frontline healthcare and support workers over unpaid salaries, bonuses and dangerous conditions in eastern Congo.Previous Ebola outbreaks were marked by allegations of corruption and mismanagement of funds, which experts said have contributed to the mistrust of local communities, complicating the efforts to halt the spread.He
