On May 25, the Public Health Agency of Canada (PHAC) was notified by the US Centers for Disease Control and Prevention (CDC) about a US citizen, recently diagnosed with extensively drug-resistant tuberculosis (XDR-TB), who arrived in Montreal on a flight from Prague, Czech Republic, and then drove to the US via the Champlain, New York, border crossing.
The individual is now in contact with CDC officials and is in a U.S. hospital undergoing further evaluation.
