More MERS cases are anticipated – WHO

South Korea's outbreak of Middle East Respiratory Syndrome is "large and complex" and more cases are expected, World Health Organization experts say, the BBC reports.

But while it was premature to declare the outbreak over, the WHO said it had "found no evidence" of the Mers virus spreading wider in the community.

About 140 people have been infected since the start of the outbreak last month. Fourteen are known to have died.

Experts also urged the South Korean government to stay vigilant.
