Nigeria requested the experimental Ebola drug ZMapp on Wednesday, as the country reported its third death from the virus ravaging several West African nations, dpa reported. "The Nigerian government has reached out to the United States Center for Disease Control to request for the unapproved Ebola drug, ZMapp, for the treatment of affected persons in Nigeria," said Information Minister Labaran Maku, adding it was still awaiting a response from Washington. The appeal came a day after the World Health Organization (WHO) said untested treatments could be given to patients given the severity of the Ebola outbreak - the worst in history. Canada's Public Health Agency said it could send between 800 to 1,000 doses of a different experimental Eboal drug to the WHO. Nigeria is the second African country to request ZMapp after Liberia. Guinea, Liberia, and Sierra Leone, which share a border, have been the hardest-hit countries by Ebola.
