The South African National Blood Service (SANBS) has found that there is a high percentage of people who have antibodies to fight Covid-19 in South Africa.
The organisation, which looks at blood being donated by blood donors in the country, have found that South Africans are building up immunity against Covid-19 with each wave of the virus.
A study conducted by the SANBS found that the number of blood donors who have Covid-19 antibodies increased from 47% during the wave of the Beta variant, to 71% during the Delta wave.
Executive, transfusion medicine, and technical services at SANBS, Marion Vermeulen believes that 71% of the country's population have been exposed to Covid-19.
She explained that their last survey which was conducted in November 2021 revealed that 55% of blood donors tested positive for Covid-19. This was then extrapolated in the general population which, through estimation, believes that 71% of the population was exposed to Covid-19.
“We saw that with Omicron there were a number of people that got reinfected but those antibodies still seem to provide some protection with regard to severe illness. These antibodies are only people who have been exposed, this does not even include people who have been vaccinated,” added Vermeulen.
In the last 24 hour cycle, 3 056 new Covid-19 cases were reported in South Africa. The National Department of Health reported 435 deaths and of these, 17 occurred in the past 24 to 48 hours according to the institute, a division of the National Health Laboratory Service.
The total number of deaths reported in South Africa due to Covid-19 related illnesses has increased to 97 955.
