At least, three deaths have been recorded so far and WHO says they are taking the situation “very seriously”.
One of those killed had tested positive for Ebola after coming down with a haemorrhagic fever last month in Bas-Uele, a province which borders the Central African Republic.
WHO spokesman Christian Lindmeier noted that work is under way to find people who may have been in contact with the Ebola sufferer.
The health agency’s regional director is also on their way to Bas-Uele, where residents are being given advice on how to treat their loved ones and perform safe burials.
Another WHO spokesman, Eric Kabambi, said:
The case is in a very remote zone, very forested, so we are a little lucky.
In a statement, the DRC’s health ministry said:
Our country must confront an outbreak of the Ebola virus that constitutes a public health crisis of international significance.
