Covid-19 positivity rate hits 22%

The positivity rate of Covid-19 tests in South Africa reached 22% on Sunday.

This comes after the South African Medical Research Council said last week that the occurrence of Covid-19 particles in the Sewage is increasing in three provinces.

Daily official updates released by the National Institute for Communicable Diseases (NICD) on Sunday showed that 3,838 infections had been detected in the past 24 hours – fewer than the figures reported last week. This was out of 17,473 tests performed.

No deaths were recorded, but 44 people were hospitalized.

Most new cases were reported in Gauteng (46%). and KwaZulu-Natal (29%). The Western Cape accounted for 11%, the Free State 4%, the Eastern Cape 3%, Mpumalanga and the North West each 2%, and the Limpopo and North Cape each 1%.

The NICD announced the New case positive rate is now 22%, higher than yesterday (21.5%), with the seven-day average positivity rate now at 20.4%.

Because many Covid-19 infections are receding undiagnosed, the positivity rate is taken as an indication of how quickly it is spreading. Rate is a measure of test level relative to outbreak size. Because limited testing makes it likely that many cases will be missed, the positivity rate can reveal where and how quickly the virus is spreading.

In November, SA announced the discovery of the Omicron variant and was the first country to experience a wave of infections caused by Omicron.

While scientists have predicted the start of the next wave sometime this month, the government is hoping vaccination will mitigate the effects.
