MONROVIA, Liberia — A Liberian doctor who received one of the last known doses of an experimental Ebola drug has died, officials said Monday.
The experimental drug known as ZMapp has been tried in only six people. Health experts caution that since ZMapp was never tested in humans, it is unclear whether it works. The small supply is now said to be exhausted and it is expected to be months before more can be produced.
Dr. Abraham Borbor, the deputy chief medical doctor at Liberia's largest hospital, had received ZMapp, along with two other Liberians. He "was showing signs of improvement but yesterday he took a turn for the worse," and died Sunday, Information Minister Lewis Brown told the Associated Press.
There was no update on the two other Liberians.
Earlier, it had been given to two American aid workers and a Spanish missionary priest, who died after he left Liberia. After receiving rigorous medical care in the United States, the Americans survived the virus that has killed about half of its victims.
The virus is transmitted through direct contact with the bodily fluids of the sick or from touching victims' bodies, leaving health care workers most vulnerable to contracting it.
