The global risk “remains low” from a deadly Ebola outbreak centred in the Democratic Republic of Congo, the World Health Organization chief said Wednesday, after a case was confirmed in France.

France on Wednesday announced its first confirmed case of Ebola identified on its territory: a doctor who had flown back from the DR Congo, which is fighting a major outbreak.

The case is the first of the deadly haemorrhagic fever identified outside the African continent during the current outbreak, which has also affected Uganda.

WHO chief Tedros Adhanom Ghebreyesus warned against “over-reaction” to the case — the first ever detected in France.

There is “no need for panic”, he said, insisting that “the risk to the rest of the world is low”.
