A day after World Health Organization said the Ebola outbreak in the Democratic Republic of Congo was on track to surpass the deadliest in history, officials said it has spread to a sixth province.

The Africa Centres for Disease Control and Prevention on Thursday said a man who had travelled from a neighbouring region has died in the previously unaffected Bas-Uele province.

He was a motorcycle-taxi driver who had sought treatment at several hospitals before he passed away in Buta, and tested positive for the haemorrhagic virus posthumously.

His colleagues then tried to forcibly take his body, prompting police intervention and concerns that more people may have been exposed to the illness.

The death toll of 2,100 people so far in the outbreak in eastern Congo, has been reached almost three times faster than in the 2014 to 2016 epidemic in West Africa.
