A British Columbia man has been confirmed as Canada's second case of H7N9 bird flu.

The unidentified man and his wife are believed to have contracted the virus during a recent trip to China.

They are the first North Americans known to have been infected with this virus.

B.C.'s deputy provincial health officer says the positive test result was confirmed late Thursday by the National Microbiology Laboratory in Winnipeg.

But Dr. Bonnie Henry says the province does not expect to see more cases associated with this event.

She says none of the couple's contacts have become ill, and if they were going to, they would have by now.

The couple returned to Canada on Jan. 12 and became ill a couple of days later. Both have since recovered.
