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.
Uganda last reported an Ebola outbreak in 2022.
The index patient's wife is the second confirmed case, and 3 close contacts are isolated for treatment and testing.
In a related development, Ugandan scientists who sequenced the virus say they don't see a link to the country's 2022 outbreak.
The index patient is a 32-year-old man who worked as a nurse at a hospital in Kampala and died after seeking care at multiple facilities.
