Since 2000, South Africa has made significant progress towards controlling malaria, reducing incidence of the disease from 11.1 to 2.1 total cases per 1,000 population at risk, and shrinking the at-risk area down to portions of just three Provinces. However, despite sustained efforts, transmission has plateaued, requiring innovative methods for getting to zero.
Historically, reported cases were mapped to the health facility or the Sub-District level to understand burden of disease. While important for many operational reasons, mapping cases to the health facility indicates where treatment occurs, but may miss where transmission and infection actually occur. Acceleration toward malaria elimination will require increasingly accurate, fine scale stratification of malaria transmission, especially as transmission becomes increasingly heterogeneous. This accurate stratification of source of infection at the local level provides critical information to the programme on how best to direct limited dedicated resources, enabling more accurate and effective targeting of interventions such as vector control measures,
South Africa’s malaria programme has renewed their commitment to increasing fine-scale stratification and mapping in the new National Malaria Elimination Strategic Plan (2019-2023). To reach the goal of malaria elimination, they have utilized geographic information systems to enable fine-scale mapping, leveraging myriad data sources including open-source data, participatory mapping from provincial leaders, and case-based geographic data from the new DHIS2-based national malaria information surveillance system. Stratification of source of infection at the local level will help to ensure systematic elimination of malaria from municipalities and districts until South Africa is malaria-free.
