BEIJING, Oct. 30 (Xinhuanet) -- The World Health Organization says it has confirmed 10 cases of polio in northeast . It’s the first confirmed outbreak of the disease in the country in 14 years.

The UN health agency also says there is a high risk of the disease spreading across the region. The origin of the outbreak is still being investigated.

"The next step will be to genetically look at these isolated viruses and see where they came from, so that should give some clarity on the origin. A lot is still unknown and investigations are still ongoing. They all appear to be very young, so less than aged 2, and they all appear to be under- or un-immunised," said Oliver Rosenbauer, spokesman of World Health Organization.
