Prevention of new HIV infections is crucial for controlling the HIV epidemic. Despite HIV pre-exposure prophylaxis (PrEP) being one of the highly effective approaches to preventing HIV, and being freely available through primary healthcare clinics (PHCs), the uptake of HIV PrEP in South Africa (SA) is low. ⋯ Among the healthcare workers tasked with generating demand and identifying clients eligible for HIV PrEP services, low knowledge of HIV PrEP and negative attitudes towards HIV PrEP may be barriers to the uptake of HIV PrEP. Training healthcare workers on HIV PrEP is recommended.

The coronavirus disease 2019 (COVID-19) pandemic placed an unprecedented strain on intensive care units (ICUs) in South Africa. Infection prevention and control (IPC) strategies were highlighted to minimise the risk to healthcare workers and for the protection of patients from contracting hospital-acquired infections (HAIs). During the third wave, our institution adopted a shift system to address severe burnout among ICU personnel. We noted an upstroke in the occurrence of HAIs, specifically carbapenem-resistant Enterobacterales (CRE) and multidrug-resistant (MDR) Acinetobacter baumannii. ⋯ We observed a very significant rise in HAIs in the COVID-19 ICU during the third wave compared with the first, with almost three times as many patients developing HAIs. Unsurprisingly, it was associated with a longer mean stay in ICU and a higher mortality. The outbreak of both CRE and A. baumannii, and the fact that many patients cultured the same CRE organism and A. baumannii, strongly suggests that a critical breakdown in IPC measures had occurred.

While the majority of COVID-19 cases in South Africa (SA) are mild, patients with severe COVID-19 requiring hospitalisation present with significant morbidity and mortality and place a substantial burden on healthcare services. Given the low vaccine uptake in SA and other low- and middle-income countries in sub-Saharan Africa, the high prevalence of comorbidities and limited healthcare system capacity, evidence-based interventions that reduce the risk of severe disease and death should be considered for implementation. ⋯ COVID-19 antivirals such as remdesivir, nirmatrelvir/ ritonavir and molnupiravir are safe and cost-effective and have received either full approval or emergency use authorisation from regulators. Using a proposed test-and-treat strategy, judicious use of antivirals could be impactful.

Mercury is a highly toxic heavy metal that may cause neurological, respiratory, gastrointestinal and dermatological illnesses. Previously described neurological manifestations of mercury toxicity are symmetrical, and include a pancerebellar syndrome, generalised seizures and encephalopathy. Mercury is used in the gold mining process, and in artisanal or illicit gold mining, often without necessary protection. ⋯ The neurological manifestations of mercury toxicity are typically symmetrical, whereas our two patients presented with markedly asymmetrical features. It is important to maintain a high index of suspicion for mercury poisoning, even in patients with atypical and unilateral or asymmetrical presentations. A prompt diagnosis and the commencement of early chelation therapy have the potential to produce good outcomes.
