When an orphanage in Bunia took in a newborn baby after his mother died from Ebola, the nuns who ran it hoped they were giving the infant a chance for life. The baby survived for only another two weeks. Now four of the nuns who cared for him have fallen sick with the deadly virus.
It is a snapshot of the tragedies at the centre of an outbreak in which the number of victims is roughly doubling every week, according to the World Health Organization (WHO).
