An experimental Ebola drug, ZMapp, has cured all 18 of the laboratory monkeys infected with the deadly virus.
According to Reuters, these include those suffering the fever and hemorrhaging characteristics of the disease and had been hours from death.
Monkeys not treated until five days after infection also survived.
Reportedly, no other experimental Ebola therapy has shown such success in primates. Five days of infection in the animals has been said to be the equivalent of nine to 11 days after infection in humans.
Although, two American aid workers who contracted Ebola in Liberia were cured after receiving ZMapp, their physicians do not know if the drug helped.
