Asymptomatic carriage of Streptococcus pyogenes (Strep A) may contribute to transmission, yet its role remains poorly understood and evidence on optimal detection methods is limited. While self-collected throat swabs are used in infectious disease surveillance, their value for identifying asymptomatic Strep A carriage in adults is uncertain. This pilot prospective cohort study, conducted at a Perth medical research institute between August and October 2024, assessed feasibility and acceptability of self-collection, with sensitivity as a secondary objective.
Life-threatening invasive infections caused by Streptococcus pyogenes and Streptococcus dysgalactiae subsp. equisimilis (SDSE) are unpredictable, frequently fatal, and are increasing in incidence globally. In the absence of evidence from randomized controlled trials (RCTs), clinical management for these conditions varies. Understanding current management approaches and areas of clinical equipoise will inform planning of feasible high-impact RCTs.
Acute rheumatic fever is an autoimmune disorder resulting from Group A Streptococcus pharyngitis or impetigo in children and adolescents, which may evolve to rheumatic heart disease (RHD) with persistent cardiac valve damage. RHD causes substantial mortality and morbidity globally, predominantly among socioeconomically disadvantaged populations, with an interplay of social determinants of health and genetic factors determining overall risk.
Antibiotic consumption can lead to antimicrobial resistance and microbiome imbalance. We sought to estimate global antibiotic consumption for sore throat, and the potential reduction in consumption due to effective vaccination against group A Streptococcus.

Recent research has documented a wide range of health, economic, and social benefits conferred by vaccination, beyond the direct reductions in morbidity, mortality, and future healthcare costs traditionally captured in economic evaluations.
Disease caused by Streptococcus pneumoniae is associated with considerable morbidity and mortality in children. Pneumococcal conjugate vaccines are well tolerated and effective at reducing pneumococcal disease caused by vaccine serotypes. VAXNEUVANCE (V114) is a 15-valent PCV containing 13 serotypes in Prevnar 13, plus serotypes 22F and 33F. This large phase 3 study evaluated safety and tolerability of V114 in infants.
Secondary prevention of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) involves continuous antimicrobial prophylaxis among affected individuals and is recognised as a cornerstone of public health programmes that address these conditions. However, several important scientific issues around the secondary prevention paradigm remain unresolved.
Acute rheumatic fever (ARF) is a multiorgan inflammatory disorder that results from the body's autoimmune response to pharyngitis or a skin infection caused by Streptococcus pyogenes (Strep A). Acute rheumatic fever mainly affects those in low- and middle-income nations, as well as in indigenous populations in wealthy nations, where initial Strep A infections may go undetected.
