Only about 50% of cases of Ebola in the Democratic Republic of Congo are being identified, the government's response co-ordinator has said.
Jean-Jacques Muyembe warned that the current deadly outbreak could last up to three years.

He said a man who died this week in the city of Goma, on the Rwandan border, had 10 children and had infected a number of people.

The Ebola outbreak has killed more than 1,800 people in the past year.

At least 2,700 people have been infected in the worst Ebola outbreak in the DR Congo's history.

Tackling the disease has also been complicated by conflict in the region.

Earlier this week, Rwanda briefly closed its border with the DR Congo amid fears the disease would spread to the country.

Speaking in Goma on Friday, Mr Muyembe said more needed to be done to tackle the outbreak, as an estimated half of Ebola cases were going unidentified.

"If we continue on that basis, this epidemic could last two or three years," Mr Muyembe warned.

Speaking about the latest victim in Goma, a gold miner, he said that the man "will have contaminated several people".

"But for the moment it is only his wife and one of his 10 children who are sick," Mr Muyembe said.

He added that the miner's sister had travelled to South Kivu province, but was quickly located and brought back to Goma.

Cases in the city earlier prompted the World Health Organization (WHO) to declare the outbreak as an emergency of international concern.
