Although the patient has been allowed to leave, 46 people who had come in contact with her are still being monitored. All the aspects of the Ebola response remain in place to ensure that any new cases are detected quickly and treated. The end of the outbreak can only be ascertained when no infections arise 42 days after the last reported case has tested negative.

“I applaud the tireless efforts that have been made to respond to this outbreak and I’m truly encouraged by the news that the last Ebola patient has left the treatment centre healthy,” said Dr Matshidiso Moeti, the World Health Organization (WHO) Regional Director for Africa. “It is not yet the end of Ebola in the Democratic Republic of the Congo. We must stay vigilant in the coming weeks and beyond.”

The current outbreak, which was declared on 1 August 2018, is the DRC’s tenth and the second-worst globally after the 2014–2016 epidemic in West Africa. As of 1 March, there were 3 444 confirmed and probable cases and 2 264 deaths.

Surveillance, pathogen detection and clinical management are ongoing, including validating alerts, monitoring the remaining contacts, supporting rapid diagnostics of suspected cases and working with community members to strengthen surveillance on deaths in the communities.
