The Public Health Agency of Canada has confirmed the country’s first case of a more severe type of mpox in a person in Manitoba, though it says the risk to the general population remains low.

The agency says the travel-related case is associated with an ongoing outbreak of what’s known as clade 1 mpox in central and eastern Africa.
