China on Alert After First Mers Case

China is trying to track down at least 193 people who may have come in contact with a man with Mers, the country's first confirmed case of the virus.
The alert came as South Korea announced it had two more Mers cases, bringing the total within the country to nine.
China's first case was another South Korean who had ignored quarantine restrictions and flew to Hong Kong, before travelling south by bus.
It confirmed the case on Thursday night, two days after the 44-year-old made the trip.
