It’s not just droplets: a systematic review and meta-analysis of the modes of transmission of Group A Streptococcus

The transmission of Group A Streptococcus (Strep A) through respiratory droplets has been considered the dominant mode of transmission to date; however, little is known about the relative contribution of other modes of transmission. This review systematically summarises the contemporary evidence regarding the transmission of Strep A.

Addressing normalization using culturally relevant approaches: An important adjunct to reducing the burden of impetigo and scabies

Impetigo, a bacterial infection caused by Streptococcus pyogenes and S. aureus of the superficial dermis affects up to 162 million children at any one time. Three out of every five school-children in Samoa have active or recently healed impetigo, far higher than the global median impetigo prevalence surpassing previous estimates for the Oceania region.

Subcutaneous infusion of high-dose benzathine penicillin G is safe, tolerable, and suitable for less-frequent dosing for rheumatic heart disease secondary prophylaxis: a phase 1 open-label population pharmacokinetic study

Since 1955, the recommended strategy for rheumatic heart disease secondary prophylaxis has been benzathine penicillin G injections administered intramuscularly every 4 weeks. Due to dosing frequency, pain, and programmatic challenges, adherence is suboptimal. It has previously been demonstrated that BPG delivered subcutaneously at a standard dose is safe and tolerable and has favorable pharmacokinetics, setting the scene for improved regimens with less frequent administration.

Morbidity of Scabies in Resource-Limited Countries: Rheumatic Heart Disease (RHD) and Post-Streptococcal Glomerulonephritis (APSGN)

Scabies is one of the world’s most prevalent diseases, with approximately 147 million cases at any one time and an estimated annual incidence of 455 million new episodes. Although Group A streptococcal (GAS) pharyngitis has long been implicated in the pathogenesis of acute rheumatic fever (ARF) and subsequent rheumatic heart disease (RHD), impetigo caused by GAS has recently been postulated as a link between scabies and the pathogenesis of ARF.

Progress towards a coordinated, national paediatric antimicrobial resistance surveillance programme

These data support that children are not just 'little adults' in the AMR era, and analyses by age group are important to detect differences in antibiotic susceptibility

The Investigation of Health-Related Topics on TikTok: A Descriptive Study Protocol

The social media application TikTok allows users to view and upload short-form videos. Recent evidence suggests it has significant potential for both industry and health promoters to influence public health behaviours. This protocol describes a standardised, replicable process for investigations that can be tailored to various areas of research interest, allowing comparison of content and features across public health topics.

Skin Health Situational Analysis to inform skin disease control programs for the Kimberley - outcomes

The Skin Health Situational Analysis was conducted in 2017 with and for stakeholders in the Kimberley region as a precursor to the SToP Trial to highlight all that was already known prior to commencement in 2018. It was completed to be a resource for communities in the Kimberley who would like to de
