Health officials are investigating an alarming spike in Ebola cases in the Democratic Republic of the Congo, with many blamed on a single individual who appears to have contracted the disease for a second time this year.

Amid the struggle to bring the 16-month outbreak under control, the World Health Organization noted an almost 300% increase in cases in the last three weeks, with 17 of 27 linked to a single chain of transmission.
