        Intervention effect of targeted workplace closures may be approximated by single-layered networks in an individual-based model of COVID-19 control

        Individual-based models of infectious disease dynamics commonly use network structures to represent human interactions. Network structures can vary in complexity, from single-layered with homogeneous mixing to multi-layered with clustering and layer-specific contact weights. Here we assessed policy-relevant consequences of network choice by simulating different network structures within an established individual-based model of SARS-CoV-2 dynamics. ...

        Individual variation in vaccine immune response can produce bimodal distributions of protection

        The ability for vaccines to protect against infectious diseases varies among individuals, but computational models employed to inform policy typically do not account for this variation. Here we examine this issue: we implement a model of vaccine efficacy developed in the context of SARS-CoV-2 in order to evaluate the general implications of modelling correlates of protection on the individual level. ...

        COVID-19 vaccine coverage targets to inform reopening plans in a low incidence setting

        Since the emergence of SARS-CoV-2 in 2019 through to mid-2021, much of the Australian population lived in a COVID-19-free environment. This followed the broadly successful implementation of a strong suppression strategy, including international border closures. With the availability of COVID-19 vaccines in early 2021, the national government sought to transition from a state of minimal incidence and strong suppression activities to one of high vaccine coverage and reduced restrictions but with still-manageable transmission. ...

        The role of children in transmission of SARS-CoV-2 variants of concern within households: an updated systematic review and meta-analysis, as at 30 June 2022

        Meta-analyses and single-site studies have established that children are less infectious than adults within a household when positive for ancestral SARS-CoV-2. In addition, children appear less susceptible to infection when exposed to ancestral SARS-CoV-2 within a household. The emergence of SARS-CoV-2 variants of concern (VOC) has been associated with an increased number of paediatric infections worldwide. ...

        Life in a time of COVID: retrospective examination of the association between physical activity and mental well-being in western Australians during and after lockdown

        The aim of this study was to examine physical activity and sedentary behaviours during Western Australia's COVID-19 lockdown and their association with mental well-being. ...

        A modelling approach to estimate the transmissibility of SARS-CoV 2 during periods of high, low, and zero case incidence

        Against a backdrop ofwidespread global transmission, a number of countries have successfully brought large outbreaks of COVID-19 under control and maintained near-elimination status. A key element of epidemic response is the tracking of disease transmissibility in near real-time. During major out-breaks, the effective reproduction number can be estimated froma time-series of case, hospitalisation or death counts. In low or zero incidence settings, knowing the potential for the virus to spread is a response priority. ...

        The Emerging Omicron Variant, Children and School

        Many publications have demonstrated the detrimental effects of school closures on children, families and communities in the past two years of the COVID-19 pandemic. Currently, there is a surge of Omicron cases as children prepare to return to school around the world. While many children are asymptomatic or have mild disease, it is nevertheless an important problem. ...
