Another mainland case suspected

A Chinese man who recently traveled through the US and Canada could become the mainland's fourth confirmed victim of A(H1N1) flu.

The 59-year-old man surnamed Yang, of Nanhai city in Guangdong province, returned to the mainland on Friday after an independent overseas tour in late April. Yang caught Korean Air flight KE020 from Seattle to Seoul last Tuesday. The next day he caught Korean Air flight KE607 to Hong Kong.

Yang developed a sore throat, blocked nose, and began coughing on Thursday.
