Due to climate change and other pressures, the frequency and scale of cholera outbreaks in southern Africa is rising. Outbreaks are occurring in places that rarely experienced them before, with impacts that are often more severe than they should be. In mid-May 2023, Hammanskraal in South Africa’s Gauteng Province became the epicentre of the second biggest cholera outbreak in the country this century, resulting in approximately 900 cases and 34 deaths. To ensure that emergency response teams in South Africa will be able to respond quickly and contain any future cholera outbreaks that may occur, MSF teamed up with the National Department of Health (NDoH), the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) to deliver cholera readiness trainings for government teams from all nine provinces. The trainings were a blend of theory and outdoor simulation exercises, which gave the participants hands-on experience in chlorinating water to the right specifications, and setting up cholera treatment units.
