Hopes of a
breakthrough in the fight against Ebola have been raised by the 100 per
cent successful treatment of monkeys with the deadly disease.
The
experimental drug ZMapp cured the animals even when administered five
days after infection, while they were displaying severe symptoms.
All
18 rhesus macaques made a complete recovery, in contrast to three other
untreated monkeys that quickly fell seriously ill and died.
ZMapp is a blend of three laboratory-made antibodies designed to neutralise the virus.
Two U.S. doctors given the drug after they were infected with Ebola while working in Liberia subsequently recovered.
But
it is not known whether they were saved by the drug or just lucky.
About 45 per cent of those infected in the current outbreak have
survived without treatment.
At least two other patients treated with ZMapp have died, possibly because help got to them too late.
The
new research, published in a special report on Nature journal's
website, provides hard evidence that the drug works and can be highly
effective.
