“SARS-CoV-2 antibody surveys can be used to more accurately estimate how many people in the country have been infected with the virus that causes COVID-19. A few such surveys are underway in South Africa. In Gauteng, a survey has gathered data from just under 3,000 people. In total the survey aims to test 14,000 people from 7,000 households.”
