Professor Riana Borman’s research seeks to understand the effects of endocrine-disrupting chemicals (EDCs) on human and environmental health, with a special focus on male reproduction. Most of her research is carried out in the rural areas of the Vhembe District in Limpopo, in communities where insecticide is sprayed to control malaria-carrying mosquitoes.
She began her career in the Department of Urology at the University of Pretoria (UP) in 1980 and had a research topic to explore within the first week, which triggered a career-long curiosity. “I am still researching the role of EDCs on human health today,” she says.

Prof Bornman, who obtained an MBChB at UP, says her research focus developed from her experiences in managing patients in clinical settings. “As a clinical physician, I realised that human and environmental health was intricately affected by environmental pollution, especially exposure to EDCs. Being a clinician at UP has created unique opportunities to conduct research in the Limpopo province.”

Her field of research addresses the unintentional health consequences of annual indoor residual spraying of insecticides to control malaria-carrying mosquitoes. In the Vhembe District, dichlorodiphenyltrichloroethane (DDT) is sprayed to control these mosquitoes and reduce cases of malaria and death. While DDT is largely a banned chemical, according to the Stockholm Convention on Persistent Organic Pollutants, it is allowed in some countries, including South Africa, for malaria vector control.

Dr Taneshka Kruger has been doing research at the University of Pretoria (UP) since 2012, which was when she did her postdoctoral fellowship on an innovative malaria mosquito vector control method. She joined the UP Institute for Sustainable Malaria Control (ISMC) as project manager and coordinator in the same year. Dr Kruger is also responsible for marketing the institute, and her research focus contributes to this.

Her research focus is innovative and novel malaria education and health promotion as proactive malaria transmission prevention methods and strategies. A large proportion of malaria deaths occur annually in children under five years of age. Dr Kruger’s research and communication initiatives often have her working directly with malaria-endemic communities, especially with young children of primary school age, in the rural Vhembe District in northeast Limpopo. The aim is to raise malaria awareness and to teach children how to prevent contracting the disease.

Malaria is still a major public health concern, with hundreds of thousands of people dying annually from the disease, despite it being both preventable and treatable. Dr Kruger says her research matters because it contributes towards proactive malaria prevention strategies, specifically identifying novel education and health promotion interventions that have the potential to contribute towards malaria elimination.
