A large and isolated region of northeastern Canada entered a lockdown this week as cases of COVID-19 creep up in parts of the country with limited access to advanced medical care.

More than 80 cases have been identified this month in Nunavut, where around 39,000 people, predominantly Inuit, live in communities scattered across a territory the size of Mexico. The worst-hit area, Arviat, has 58 cases in a hamlet of fewer than 3,000 people.

The new lockdown started Wednesday and is set to last two weeks.
