A group of researchers from various universities across the country have published a paper in the South African Medical Journal entitled “Understanding the differential impacts of Covid-19 among hospitalised patients in South Africa for equitable response”. The team looked at Covid hospital admissions between March 6 2020 and January 24 2021, and found that “an analysis of race, age and sex rates of hospitalisation showed variation”. Black African females had the highest hospitalisation rates at a younger age category of 30 to 39 years compared with other race groups. We speak to Prof Refilwe Phaswana-Mafuya,  professor of epidemiology and public health at the University of Johannesburg.
