Cambodia has reported 32 deaths from the coronavirus, a record daily increase, as authorities warn of the risk of a new wave of infections driven by the Delta variant.

The Southeast Asian country has recorded one of the world’s smallest virus caseloads, but an outbreak first detected in late February has driven up total cases to 52,350, with 660 deaths, Reuters reports.

In a speech on Thursday, Prime Minister Hun Sen had warned of the risk of another wave.

“There could be a third wave if no action is taken in time, because now there is a new outbreak caused by the Delta variant, and not just in Cambodia, but in the world,” Hun Sen said.
