MEXICO CITY (Reuters) - The new H1N1 flu killed its first patient in Canada, making it the third country after Mexico and the United States to report a death from the virus that has sickened more than 3,000 people in 27 countries.
Alberta's chief medical officer said on Friday that the woman in her 30s who died on April 28 had not traveled to Mexico, the epicenter of the swine flu outbreak, which suggests a more sustained spread of the infection.
Her death raised the confirmed global death toll to 48 from the virus, a strange coupling between a triple-hybrid virus with pig, human and bird elements and a European swine virus not seen before in North America.
Alberta was also where a herd of pigs became infected with the H1N1 swine flu, apparently infected by a man who had traveled to Mexico.
The World Health Organization kept its global pandemic alert at 5 out of 6 because the new virus was not spreading rapidly outside North America, where U.S. officials expect it to spread to all 50 states.
