The World Health Organization authorized the use of experimental drugs in the fight against Ebola on Tuesday as the death toll topped 1,000 and a Spanish priest became the first European to succumb to the latest outbreak of the virus.
The declaration by the UN's health agency came after a US company that makes an experimental serum said it had sent all its available supplies to hard-hit west Africa.
"In the particular circumstances
of this outbreak, and provided certain conditions are met... it is
ethical to offer unproven interventions with as yet unknown efficacy and
adverse effects," the WHO said in a statement following a
teleconference between medical experts.
The
current outbreak, described as the worst since Ebola was first
discovered four decades ago, has now killed 1,013 people since early
this year, the WHO said.
Cases
have so far been limited to Guinea, Liberia, Sierra Leone and Nigeria,
all in west Africa where ill-equipped and fragile health systems are
struggling to cope.Monrovia said it had requested samples of an experimental drug, ZMapp, that has shown some positive effects on two US aid workers but failed to save the Spanish priest.
Supplies would be brought in by a representative of the US government later this week, the Liberian government said.
There
is currently no available cure or vaccine for Ebola, which the WHO has
declared a global public health emergency, and the use of experimental
drugs has stoked an ethical debate.
- Early phase -
Despite
promising results for the ZMapp treatment, made by private US company
Mapp Bio pharmaceutical, it is still in an early phase of development and
had only been tested previously on monkeys.
ZMapp
is in very short supply, but its use on the Western aid workers
evacuated to the United States last week triggered controversy and
demands that it be made available in Africa.
Mapp said it had sent all its available supplies to West Africa.
