FREETOWN, Sierra Leone – Earlier this year, experts believed the Ebola outbreak in West Africa was about to come to an end.
The World Health Organization reported on Wednesday that a steady decline in the number of Ebola cases is over. Now, the numbers are going back up in Guinea and Sierra Leone.
At this point, experts say it is not entirely clear where some of the patients were infected.
Health care workers hope to track down and check everyone who might have been in close contact with patients.
“A total of five of the 16 cases reported from Guinea arose from unknown sources of infection,” WHO said.
So far, Ebola has infected more than 27,000 people and killed more than 11,000 in West Africa, according to NBC News.
