Another 42,848 COVID-19 cases and 127 coronavirus-related deaths have been recorded in the latest 24-hour period.
That compares to 50,584 infections on Friday and 143 deaths.
A week ago, daily infections stood at 39,567 and fatalities at 131.
The number of booster vaccinations – or third doses – administered has risen to 19,809,442 (34.4% of the population aged 12 and over).
The latest number of people in hospital with COVID is 7,373 – a drop of almost 2,300 since the start of November.
In other news, a marked rise has been seen in the number of children admitted to hospital in South Africa – the epicentre of the new Omicron variant – but cases are “mild”, a public health expert has said.
The increase has sparked concerns that the latest COVID-19 strain, which has spread rapidly around the world, could pose a greater risk to youngsters.
