SINGAPORE -- One British man, one Malaysian and two South Koreans. Four cases of the new coronavirus had something in common: All of the patients had been to a business conference at the Grand Hyatt Singapore hotel in late-January.
At the time, there were only around 200 confirmed infections outside China. The Malaysian man became his country's first case. The British visitor is believed to have transmitted the virus to several others while skiing in France. Three Singapore residents are also thought to have been infected at the meeting, which involved 109 participants from across the globe, including some from the Chinese province of Hubei.
