Cases are declining in some hot spot countries, as officials warns that nations outside Africa are still reporting imported cases.
Suspected case-patients, one of them a woman who became ill while pregnant, have links to the western part of Uganda.
The newly confirmed cases are linked to a 4-year-old boy who died from his Ebola infection last week.
The death of a mother and her newborn baby are connected to a recent case and raise more concerns about undetected transmission.
The new case raises the death toll to 2 and the case count to 10 in this outbreak.
In the first of the 2 outbreaks, affected children had contact with bats. Further investigations are under way for both events.
Contact monitoring is still under way for 216 people who are at quarantine facilities located throughout the country.
No transmission has been found outside of a single chain, and eight patients in treatment are stable.
The death total remains at one, the index patient who died in late January.
