 The South African COVID-19 Modeling Consortium was formed in March 2020 to provide support for government planning for COVID-19 cases and related health care. Models were developed jointly by local disease modeling groups to estimate cases, resource needs and deaths due to COVID-19. Initially, the models were compartmental, but they were later adapted to include more detailed information about the clinical profiles of SARS, COV, two patients and the availability of treatment options. The models were updated 11 times between March and September 2020, with four major releases to generate new sets of projections and scenario analyses to be shared with planners in the National and Provincial Departments of Health, the National Treasury and other partners. The models were adjusted to reflect the unique characteristics of South Africa's population and health system, including its large population size and the need for greater access to treatment. Additionally, the models were updated to incorporate more local data, such as the number of people who access treatment and the impact of public health measures on the spread of the virus. This demonstrated the importance of using locally developed models to accurately assess the needs. This article was authored by Sheetal Prakash Silo, Juliet R. C. Pulliam, Jessyne Myrath and others.
