Democratic Republic of Congo Health Minister Oly Ilunga Kalenga says an outbreak of Ebola which killed four people has been brought under control.
Mr Kalenga said a new case had not been recorded for 21 days – the maximum period between exposure to the disease and initial symptoms.
Health workers used an unlicensed American vaccine to stop the disease spreading in remote terrain in the north-east of DR Congo.
