Cameron Zachreson, Ruarai Tobin, Camelia Walker +4
Residential aged-care facilities (RACFs, also called long-term care facilities, aged care homes, or nursing homes) have elevated risks of respiratory infection outbreaks and associ…
Correlation of viral loads in disease transmission chains could bias early estimates of the reproduction number
Thomas Harris, Nicholas Geard, Cameron Zachreson
Early estimates of the transmission properties of a newly emerged pathogen are critical to an effective public health response, and are often based on limited outbreak data. Here,…
Modelling the effect of within-host dynamics on the diversity of a multi-strain pathogen
Nefel Tellioglu, Nicholas Geard, Rebecca H. Chisholm
Multi-strain pathogens such as Group A Streptococcus, Streptococcus pneumoniae, and Staphylococcus aureus cause millions of infections each year with a substantial health burden. C…
Global and local epidemiology of Group A Streptococcus indicates that naturally-acquired immunity is enduring and strain-specific
Rebecca H. Chisholm, Jake A. Lacey, Jan Kokko +7
The bacterium Group A Streptococcus (Streptococcus pyogenes, GAS) is a human-specific pathogen and a major cause of global morbidity and mortality. Despite decades of research our…
