According to the latest figures, at least 1,751 people have now died as a result of the Ebola outbreak in the country.
At the same time, 3,874 cases have been confirmed.
The outbreak began in May and has been linked to the Bundibugyo variant, for which there is currently no vaccine or specific treatment.
WHO Director-General Tedros Adhanom Ghebreyesus is now calling for more comprehensive efforts to combat the spread.
"The outbreak is spreading faster than we can scale up our efforts, and the number of new cases has doubled in some hotspots in the past week alone," the WHO chief wrote on X.
