Most of Vietnam’s 22 million students returned to class today after a three-month closure to tackle Covid-19, the state-run Vietnam News Agency reported.

Eighteen of the country’s 63 provinces and centrally-run cities will open all schools starting today, while 30 others are reopening primary schools and kindergartens as secondary students went back in late April.

Ten other localities including the main cities of Hanoi and Ho Chi Minh City will resume primary schools and kindergartens later.

VNA reports many schools have “rearranged desks while others had to consider dividing classes into smaller ones” but that many schools are facing “difficulties in keeping the minimum distance of one metre among students due to the shortage of teachers and classrooms.”

In addition, some schools changed class schedules and will continue to teach through the internet and televised classes.
