Article:

In the wake of the coronavirus disease 2019 (COVID-19) pandemic, the links between poor hygiene, unclean environments and human health cannot be overemphasised, particularly in South Africa with its high incidence of infectious diseases and overburdened health system. One very controllable factor that is often overlooked is the poor disposal of litter and waste management and its adverse effects on public health. By wearing masks, regular handwashing and sanitising, as well as making sure that neighbourhoods and public spaces are clean and safe, the spread of COVID-19 and other diseases can be prevented.
