When two American aid workers recovered from Ebola after being treated with an experimental drug, the grieving family of Sierra Leone's most famous doctor wondered why he had been denied the same treatment before he died from the deadly virus.
Sheik Umar Khan was a hero in his small West African country for leading the fight against the worst ever outbreak of the highly contagious hemorrhagic fever, which has killed 1,427 people mostly in Sierra Leone, Liberia and Guinea.
When Khan fell sick in late July, he was rushed to a treatment unit run by Medecins Sans Frontieres (MSF) where doctors debated whether to give him ZMapp, a drug tested on laboratory animals but never before used on humans.
Staff agonised over the ethics of favouring one individual over hundreds of others and the risk of a popular backlash if the untried treatment was perceived as killing a national hero.
In the end, they decided against using ZMapp. Khan died on July 29, plunging his country into mourning.
A few days later, the California-manufactured pharmaceutical was administered to US aid workers Kent Brantly and Nancy Writebol who contracted Ebola in Liberia and were flown home for treatment. It is not clear what role ZMapp played in their recovery but the two left hospital in Atlanta last week.
Khan is among nearly 100 African healthcare workers to have paid the ultimate price for fighting Ebola, as the region's medical systems have been overwhelmed by an epidemic which many say could have been contained if the world had acted quicker.
In their village of Mahera, in northern Sierra Leone, Khan's elderly parents and siblings asked why he did not get the treatment. Khan saved hundreds of lives during a decade battling Lassa fever — a disease similar to Ebola — at his clinic in Kenema and was Sierra Leone's only expert on haemorrhagic fever.
“If it was good enough for Americans, it should have been good enough for my brother,” said C-Ray, his elder brother, as he sat on the porch of the family home. “It's not logical that it wasn't used. He had nothing to lose if it hadn't worked.”
Doctors who knew Khan and who were involved in the difficult decision, however, said it was based on sound ethical reasoning.
Ebola, which is passed on by direct contact with the bodily fluids of infected persons, strikes hardest at healthcare providers and carers who work closely with patients.
