OTTAWA — Health Minister Marjorie Michel says Canada is very closely following reports that a woman who worked at a plague research institute in Siberia has died. Russian authorities say the woman contracted pneumonia from an unknown source and there’s no evidence it was caused by any of the pathogens she worked with. Media outlets in Siberia have reported that the woman died of pneumonic plague, a less common but still severe form of plague. Local authorities have placed a hospital in quarantine and are monitoring people who were in contact with the woman. Michel says there’s no risk to Canada but her government is working with the World Health Organization and other countries to stay on top of the situation. U.S. Secretary of State Marco Rubio says the United States is also watching the situation closely.
