"The Omicron variant of the coronavirus could have entered the Chinese capital Beijing via contaminated mail from Canada, the city’s centre for disease control said on Monday. Pang Xinghuo, deputy director of the Beijing Centre for Disease Prevention and Control, said the city’s first Covid-19 patient to be diagnosed with the variant had received a letter mailed from Canada on January 7. “We do not rule out the possibility that the person was infected through contacting an object from overseas,” she said."
