South Africa's COVID-19 Tracing Database: Risks and rewards of which doctors should be aware

In response to the COVID-19 pandemic, South Africa (SA) has established a Tracing Database, collecting both aggregated and individualised mobility and locational data on COVID-19 cases and their contacts. There are compelling public health reasons for this development, since the database has the potential to assist with policy formulation and with contact tracing. While potentially demonstrating the rapid facilitation through technology of an important public service, the Tracing Database does, however, infringe immediately upon constitutional rights to privacy and heightens the implications of ethical choices facing medical professionals. The medical community should be aware of this surveillance innovation and the risks and rewards it raises. To deal with some of these risks, including the potential for temporary rights- infringing measures to become permanent, there are significant safeguards designed into the Tracing Database, including a strict duration requirement and reporting to a designated judge. African states including SA should monitor this form of contact tracing closely, and also encourage knowledge-sharing among cross-sectoral interventions such as the Tracing Database in responding to the COVID-19 pandemic

The practices of spray operators in the Mpumalanga Malaria Control Programme using insecticides for residual indoor spraying

Pesticide poisoning poses a health risk to individuals throughout the world. In Mpumalanga Province spray teams apply local insecticides to indoor surfaces of households just prior to the rainy season to control malaria. Workers are exposed to pesticides during this process. This cross sectional study compared prescribed safe handling and deltamethrin application practices of Mpumalanga malaria spray operators versus actual practices in the field. Most (91) of the spray operators were included in the study. A tick list and interview was utilized to observe field practices and enquire about reasons for non-compliance. Only 28 of operators complied with all prescribed safe handling practices. Gloves; face shields and masks were not utilized as recommended and contributed to the highest levels of non-compliance. Compliance was found to be dependent on gender; age; years of experience; education level and employment status. The low compliance rate necessitates further investigation of the malaria programme occupational safety management system. All stakeholders need to be aware of the consequences of pesticide poisoning and to collaborate in efforts to work towards prevention
