GENEVA (Reuters) - Militia violence in Democratic Republic of Congo has prevented aid workers from reaching some potential cases in an outbreak of Ebola that has so far killed 44 people, the World Health Organization said on Friday.
At least 1,500 people have been potentially exposed to the deadly virus in North Kivu province but the violence means officials cannot be sure if they have identified all the chains by which it is spreading in the east of the vast country.
"We don't know if we are having all transmission chains identified. We expect to see more cases as a result of earlier infections and these infections developing into illness," WHO spokesman Tarik Jasarevic told a news briefing in Geneva.
"The worst-case scenario is that we have these security blindspots where the epidemic could take hold that we don't know about," he said.
The WHO, using figures compiled with Congo's Health Ministry, said confirmed and probable cases numbered 78 in total, including 44 deaths. About 1,500 people have been identified as contacts of people infected with the disease, which causes fever, vomiting and diarrhoea.
The outbreak is spreading across the lush farmlands of eastern Congo. Its epicentre is the town of Mangina in North Kivu province and it has already reached neighbouring Ituri province.
Congo has experienced 10 Ebola outbreaks since the virus was discovered on the Ebola River in 1976, and it has altogether killed some 900 people altogether.
An epidemic between 2013 and 2016 killed more than 11,300 people in West Africa.
The United Nations children's agency UNICEF said an unusually high proportion of the people affected in this outbreak were children.
Two children have already died from the disease, and centres in Beni and Mangina were treating six children infected by the disease or suspected to be.
UNICEF said it had also identified 53 orphaned children who have lost their parents to Ebola.
"The impact of the disease on children is not limited to those who have been infected or suspected," said Gianfranco Rotigliano, the UNICEF representative in Congo, said in a statement.
"Many children are faced with the illness or death of their parents and loved ones, while some children have lost large parts of their families and become isolated. These children urgently need our support".
The WHO said more than 500 people including health workers have been vaccinated against the disease. It had deployed more than 100 experts to Mangina and Beni towns to oversee tracing, vaccination and safe burials.
There were however "red zones" near Mangina which aid workers could not enter for security reasons, Jasarevic said.
