A seroprevalence study among people who visited public health facilities for antenatal care and routine HIV tests in the Cape Town area found that 40% of respondents had antibodies against the coronavirus.
Researchers stressed that the results are preliminary and based on a skewed sample of 2,700 people in South Africa’s Western Cape province who aren’t representative of the overall population. A representative seroprevalence study last month of residents in India’s capital, New Delhi, found that 30% have had the coronavirus.
