New, first-in-class oral antibiotics like zoliflodacin, developed in a public-private partnership, require an optimal introduction strategy while ensuring antibiotic stewardship. Zoliflodacin, given as a single dose for uncomplicated urogenital gonorrhoea, recently demonstrated non-inferiority to ceftriaxone plus azithromycin and safety in a phase 3 randomised controlled trial. Following regulatory approval, zoliflodacin could improve sexually transmitted infection (STI) management and help address the threat of untreatable gonorrhoea, as levels of resistance to current first-line treatments increase.

African AGYW have had high uptake of oral HIV pre-exposure prophylaxis (PrEP) but low adherence, which might be improved by point-of-care adherence monitoring with tailored counselling.
Methods: From August 2022 to July 2023, we conducted a PrEP demonstration project with sexually active AGYW ages 16-30 years from 20 sites in South Africa, Eswatini, Kenya, Malawi, Uganda and Zambia.
Background: Globally, there is suboptimal coverage of antiretroviral treatment to treat and prevent HIV. It is crucial for individuals to know their partner's HIV status so they may use all appropriate and available prevention tools. For sexual minority men in South Africa, a population known to face intersecting forms of marginalization including a disparate burden of HIV incidence, there are challenges to status sharing.

This study aimed to elucidate these factors, focusing on the interplay between socio-demographic, health, knowledge, beliefs and attitudinal indicators.
Methods: This was a cross-sectional online survey administered to HCWs across South Africa between August and October 2022.
Background: Regulatory actions are increasingly used to tackle issues such as excessive alcohol or sugar intake, but such actions to reduce sedentary behaviour remain scarce. World Health Organization (WHO) guidelines on sedentary behaviour call for system-wide policies. The Chinese government introduced the world's first nation-wide multi-setting regulation on multiple types of sedentary behaviour in children and adolescents in July 2021.

This guideline aims to be a comprehensive guide for healthcare workers in Southern Africa, offering practical insights into the epidemiology, pathogenesis, clinical manifestations, diagnostic testing, therapeutic principles, and public health responses to syphilis. Although the syphilis burden has declined over the years, recent data indicate a troubling resurgence, particularly among pregnant women and neonates.

This study assessed the binding efficacy of two novel IgG1 opsonic monoclonal antibodies (MABs; GG9 & JG7) at 5, 10, and 25 µg/mL to live cultures of , , , , and American Type Culture Collection laboratory reference strains, as well as clinical susceptible, multi-drug resistant, and extensively drug resistant strains using indirect enzyme-linked immunosorbent assays. These three MAB concentrations were selected from a range of concentrations used in previous optimization (binding and functional) assays.

However, the outcomes of VDS treatment have not been well documented. This study aimed to determine the incidence, risk factors, and microbial etiology of treatment failure in women with VDS.

WHO and Foundation for Innovative New Diagnostics (FIND) have a target product profile for a non-molecular N gonorrhoeae rapid point-of-care test that requires a clinical sensitivity of greater than 80% and a specificity over 95% to be considered useful in syndromic management; test turnaround time should be 30 min or under, and the test should cost less than US$3. A novel lateral flow assay (LFA) was developed to achieve that profile.

The presence of multiple microorganisms and genital tract inflammation could be the common mechanism driving early onset of labour. South Africa has high levels of preterm birth, genital tract infections and HIV infection among pregnant women.

We used a mixed-methods design with data from a web-based self-administered survey followed by semi-structured in-depth interviews (IDIs) with selected participants. Of the 6235 HCWs included in our analysis who had fully vaccinated, 3470 (56%) had taken their booster dose with a further 17% intending to get the booster.

Methods: We systematically searched for publications in PubMed® and Scopus, manually searched the grey literature and consulted with national health and nutrition officials, with no restrictions on publication type or language. We included low- and middle-income countries in the World Health Organization South-East Asia Region, and the Association of Southeast Asian Nations and China.
Background: There is a paucity of Neisseria gonorrhoeae antimicrobial resistance data from resource-constrained settings because of the lack of diagnostic testing and limited scale of surveillance programs. This study aimed to determine the antimicrobial resistance profile of N. gonorrhoeae in the rural Eastern Cape province of South Africa.

Randomised controlled trials have recently demonstrated high effectiveness of doxycycline post-exposure prophylaxis (PEP) for prevention of bacterial STIs in MSM, with 70% - 85% reductions in infection and syphilis, and approximately 50% reduction in infection. Doxycycline PEP was not demonstrated to be effective in reducing and infection among Kenyan cisgender women.

GMB represents a set of well-defined steps to engage key stakeholders to identify shared drivers and solutions of a given problem. However, GMB has not yet been applied specifically to develop multi-duty interventions that address multiple inter-related issues such as malnutrition in all its forms (MIAIF).
