The World Health Organization (WHO) has notified a rise in the number of new Ebola cases in west Africa for the second week, after a previous fall.

A drop in new cases in recent weeks had given rise to optimism that the worst ever Ebola epidemic was coming to an end, before the WHO last week reported the first rise for 2015 in the weekly number of cases in all three countries. The WHO said, "The spike in cases in Guinea and continued widespread transmission in Sierra Leone underline the considerable challenges that must still be overcome to get to zero cases. The infrastructure, systems, and people needed to end the epidemic are now in place; response measures must now be fully implemented."
