Following a relative absence in winter 2020, a large resurgence of respiratory syncytial virus (RSV) detections occurred during the 2020/2021 summer in Western Australia. This seasonal shift was linked to SARS-CoV-2 public health measures. We examine the epidemiology and RSV testing of respiratory-coded admissions, and compare clinical phenotype of RSV-positive admissions between 2019 and 2020.
Respiratory syncytial virus (RSV) is a leading cause of childhood morbidity, however there is no systematic testing in children hospitalised with respiratory symptoms. Therefore, current RSV incidence likely underestimates the true burden.
An interseasonal resurgence of respiratory syncytial virus (RSV) was observed in Western Australia at the end of 2020. Our previous report describing this resurgence compared the 2019 and 2020 calendar years, capturing only part of the 2020/21 season.
Following the end of winter, there has been a persistent absence of severe acute respiratory syndrome coronavirus 2 community transmission and no increase in influenza detections. Limited physical distancing measures have remained in place, with largely no restrictions on gathering sizes and no mandate for wearing masks.
Acute wheezing is one of the most common hospital presentations for young children. Respiratory syncytial virus (RSV) and rhinovirus (RV) species A, B and the more recently described species C are implicated in the majority of these presentations. However, the relative importance and age-specificities of these viruses have not been defined.
Licensed recombinant protein respiratory syncytial virus (RSV) vaccines can prevent substantial morbidity in older adults. However, revaccination to prevent waning protection may be suboptimal, prompting the exploration of candidates for heterologous boosting. In this clinical trial of RSV vaccine-naive older adults, we evaluated SCB-1019T, a novel unadjuvanted bivalent RSV prefusion F (preF) protein vaccine stabilized via Trimer-Tag technology, in comparison to the licensed AS01E-adjuvanted RSV vaccine Arexvy.

Two RSV immunisations products: a maternal vaccine, Abrysvo, and a long-acting monoclonal antibody, nirsevimab, both designed to prevent RSV illness in infants, have recently become available. Modelling evidence is required to inform how to optimally use these products in immunisation programs to reduce the burden of RSV in young children.
Rhinoviruses (RV) are the most common respiratory viruses globally and a major cause of airway symptoms in children and individuals with asthma. Although more than 170 RV types exist across 3 species (RV-A, RV-B, RV-C), type-specific circulation patterns and age-related prevalence remain poorly defined.
Respiratory Syncytial Virus (RSV) causes a significant burden of illness for children under 2 years of age. Nirsevimab, a long-acting monoclonal antibody, was registered for RSV prevention in Australia in 2023. In April 2024, Western Australia (WA) launched the country's first state-wide nirsevimab program for all infants and high-risk children entering their second RSV season.
