The country has recorded 1,886 new virus cases since Saturday and 22 deaths from coronavirus.

Health Minister Joe Phaahla has urged more people to get vaccinated.

"We knew it was a matter of time before the fourth wave comes," he said during an interview with ENCA television.

Mr Phaahla says the uptake of vaccines has gone down in recent days.

The government says it has no plans to enforce a hard lockdown during the wave.

There is optimism that it will be less devastating than the other waves but the government is cautious in case of any new variants.

The fourth wave was predicted to start next month through January.
