Summarising the current knowledge of Strep A transmission to humans will address gaps in the evidence and inform prevention and control strategies. The objective of this study is to evaluate the modes of transmission and attack rates of group A streptococcal infection in human populations.

Research

This project will use a multi-jurisdictional linked RHD dataset to establish a baseline burden of RHD in Australia to allow for monitoring the impact of burden over time, and to form the basis of clearly defined targets for the END RHD CRE Endgame Strategy.

Research

Reach works to promote the health of vulnerable populations by providing technical support to local, regional and global efforts to prevent and control rheumatic fever and rheumatic heart disease (RF/RHD).

Research

The END RHD CRE will undertake a number of projects across several disciplines of research including epidemiology, biomedical sciences; implementation and translation; and understanding the RHD community with a special focus on documenting the experiences of those living with the disease.

Research

Although Streptococcus pyogenes (Strep A) is the sixth-most common infectious disease globally, its transmission within the household remains an understudied driver of infection. We undertook a systematic review to better understand the transmission of Strep A among people within the home, while highlighting opportunities for prevention. 

Research

Streptococcus dysgalactiae subspecies equisimilis and Streptococcus pyogenes share skin and throat niches with extensive genomic homology and horizontal gene transfer possibly underlying shared disease phenotypes.

Research

Knowledge gaps regarding human immunity to Streptococcus pyogenes have impeded vaccine development. To address these gaps and evaluate vaccine candidates, we established a human challenge model of S. pyogenes pharyngitis. Here, we analyse antibody responses in serum and saliva against 19 antigens to identify characteristics distinguishing 19 participants who developed pharyngitis and 6 who did not.

Chronic suppurative otitis media (CSOM), sometimes referred to as chronic otitis media, is a chronic inflammation and often polymicrobial infection (involving more than one micro-organism) of the middle ear and mastoid cavity, characterised by ear discharge (otorrhoea) through a perforated tympanic membrane.
