Canada and a growing list of more than 20 countries have confirmed cases of omicron, the latest version of the COVID-19 virus to be labelled a "variant of concern" by the World Health Organization.
Despite omicron's global reach, dozens of nations are enforcing travel bans on mainly southern Africa, where the variant was originally detected. Some countries have celebrated South Africa's identification of the variant mere moments before announcing restrictions.
Meanwhile, vaccine stockpiling by outside nations has contributed to spotty supply and high hesitancy on the continent. Africa faces a looming wave of omicron, with a full vaccination rate in the single digits.
Today on Front Burner, infectious diseases physician Dr. Zain Chagla explains how measures by countries like Canada have put Africa into this precarious position with omicron, and why vaccines are more important in regions that are currently seeing far fewer doses.
