The epidemiology of hepatitis C virus (HCV) in the general population of South Africa (SA) is incompletely understood. A high HCV prevalence in key populations is known, but data are limited in terms of a broader understanding of transmission risks in our general population. ⋯ Data from a rural town cluster of patients suggest parenteral medical exposure as the probable common source of hepatitis C transmission risk. The cohort was of older age with a significant number having advanced fibrosis or cirrhosis, suggesting HCV acquisition in the distant past. Using a simplified care approach, treatment outcomes were very good.

Suboptimal antiretroviral therapy (ART) adherence is associated with viral resistance, opportunistic infections and increased mortality. ⋯ Of HIV-positive patients presenting to the ED, a high proportion were either not yet initiated on ART or ART non-adherent. HIV programmes should focus on HIV-positive ED attendees with the aim of identifying high-risk patients and providing adequate ART adherence support.

The threat of antimicrobial resistance driven by inappropriate and unnecessary use of antimicrobials is a global issue of great concern. Evidence-based approaches to optimising antimicrobial prescribing to improve patient care while reducing the rate of antimicrobial resistance continue to be implemented worldwide. However, the successes or failures of implementation of such approaches are seldom evaluated. ⋯ An ASP requires both thorough implementation and leadership support to have an impact in the reduction of antimicrobial resistance. Lack of leadership support poses a significant challenge to sustainability. There is an urgent need for behavioural change in hospital leadership.

HIV-serodiscordant couples are at high risk of HIV transmission. In sub-Saharan Africa, HIV-serodiscordant couples contribute ~30% of all new infections in the region. ⋯ Low HIV status awareness and poor VLS among HIV-positive partners are major gaps in preventing transmission among serodiscordant couples. Intensifying programmes that target couples to test for HIV and timely antiretroviral therapy initiation could increase VLS and reduce HIV transmission.
