Presidential communication approaches and the impact on public health: a comparative analysis of three South African presidents' communication on AIDS and COVID-19.

The HIV response in the African continent over past decades demonstrates the potency that the words and actions of political leaders have in either expediting or impeding the implementation and adoption of preventive measures at the individual and community levels. The article explores the health communication approaches employed by two South African past presidents (Thabo Mbeki and Jacob Zuma) in responding to the HIV epidemic, and contrasts these with the communicative approach of President Cyril Ramaphosa during the COVID-19 pandemic. Approached from this understanding, this article provides a comparative analysis of the communication approaches of these three presidencies across the two pandemics, and considers the variously trusted sources of top-down, government-driven and bottom-up, community-informed approaches to health communication. Critical lessons that emerged in South Africa during the HIV epidemic regarding the need to include communities in communicating about risks and behaviour change have not been adopted into the COVID-19 response. Political leaders are not best placed to communicate about these issues, and, in the context of pandemics, there is a clear need to reconsider top-down communication approaches that are designed without the participation of communities and ignore the interconnected nature of health and other social determinants of health.
