Twenty-two students have been detained in a hotel in Changchun, China, as a quarantine measure against swine flu. Canadian consular officials had limited access to the students yesterday but reported they had been well treated. The Canadian Embassy in Beijing has issued a diplomatic note to the Chinese Foreign Ministry requesting further information about the detention. "At this time, we are not aware of any medical risk factors which would have supported the decision," reported Canadian Department of Foreign Affairs spokesperson Alain Cacchione. Chinese law states that the students can be held in quarantine for seven days. "The Canadian students' temperature is normal, they are in good health and their mood is stable," Ma said. "And they're satisfied with the arrangement," said Ma Zhaoxu, Chinese Foreign Ministry spokesperson. The situation has exacerbated Canadian-Chinese relations after Canada recently protested about China's import bans of Canadian pork products despite no evidence to support transmission of swine flu through food.
