The Uganda health ministry says there have been 34 suspected Ebola cases.
This is as it believes 21 deaths were probably caused by the Ebola virus.
To this effect, health teams are continuing to trace any people that may have come into contact with it.
The outbreak began in the central district of Mubende but has now spread to two neighboring districts.
The 4th outbreak of Ebola in the country is yet to be confirmed in the capital Kampala, even as neighboring countries remain on high alert.
