Spatial prediction of malaria prevalence in Papua New Guinea: a comparison of Bayesian decision network and multivariate regression modelling approaches for improved accuracy in prevalence prediction

Considerable progress towards controlling malaria has been made in Papua New Guinea through the national malaria control programme's free distribution of long-lasting insecticidal nets, improved diagnosis with rapid diagnostic tests and improved access to artemisinin combination therapy. Predictive prevalence maps can help to inform targeted interventions and monitor changes in malaria epidemiology over time as control efforts continue.

Australia needs a prioritised national research strategy for clinical trials in a pandemic: lessons learned from COVID-19

The emergence of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), sparking a global pandemic, has driven an imperative to quickly design and conduct treatment studies. We strongly propose a national, coordinated approach for randomised controlled trials (RCTs) for coronavirus disease 2019 (COVID-19), future pandemics and inter-pandemic periods in Australia.

Maps and metrics of insecticide-treated net access, use, and nets-per-capita in Africa from 2000-2020

Insecticide-treated nets (ITNs) are one of the most widespread and impactful malaria interventions in Africa, yet a spatially-resolved time series of ITN coverage has never been published. Using data from multiple sources, we generate high-resolution maps of ITN access, use, and nets-per-capita annually from 2000 to 2020 across the 40 highest-burden African countries.

Communicating with patients and the public about COVID-19 vaccine safety: recommendations from the Collaboration on Social Science in Immunisation

This article outlines the potential impacts of the AstraZeneca vaccine safety concerns. It considers the relevant heuristics and values affecting patient decision making and proposes some practical strategies for effective communication by clinicians and governments. The recommendations have been collaboratively developed by members of the Collaboration on Social Science and Immunisation (COSSI) steering group.

Global economic costs due to vivax malaria and the potential impact of its radical cure: A modelling study

An estimated 14 million cases of Plasmodium vivax malaria were reported from Asia, Central and South America, and the Horn of Africa. The clinical burden of vivax malaria is largely driven by its ability to form dormant liver stages (hypnozoites) that can reactivate to cause recurrent episodes of malaria. Elimination of both the blood and liver stages of the parasites ("radical cure") is required to achieve a sustained clinical response and prevent ongoing transmission of the parasite.

Primary prevention of acute rheumatic fever

Acute rheumatic fever (ARF) is an abnormal immune reaction following Streptococcus pyogenes (Strep A) infection of the throat, and likely the skin. Primary prevention is the prompt and appropriate antibiotic treatment of Strep A infection, and it can reduce the risk of developing ARF and subsequent rheumatic heart disease.

One vaccine for life: Lessons from immune ontogeny

There remains a general misconception that the immune status of the fetus and neonate is immature or insufficient. However, emerging research in immune ontogeny prompts reconsideration of this orthodoxy, reframing this period instead as one of unique opportunity. Vaccine responses (qualitative and quantitative) vary between individuals, and across demographic cohorts. Elements of baseline immune status and function predict vaccine response - some of these factors are well described, others remain a subject of ongoing research, especially with the rapidly expanding field of 'omics' research, enabled by development of highly granular immune profiling techniques and increasing computational capacity.

Enhanced Neutralizing Antibody Responses to Rhinovirus C and Age-Dependent Patterns of Infection

Rhinovirus (RV) C can cause asymptomatic infection and respiratory illnesses ranging from the common cold to severe wheezing. The aim was to identify how age and other individual-level factors are associated with susceptibility to RV-C illnesses. Longitudinal data from the COAST (Childhood Origins of Asthma) birth cohort study were analyzed to determine relationships between age and RV-C infections. Neutralizing antibodies specific for RV-A and RV-C (three types each) were determined using a novel PCR-based assay.

Key steps in our journey to a COVID-19 vaccine program

Providing a safe and effective coronavirus disease 2019 (COVID‐19) vaccination program is required to mitigate against the current and future negative impacts on the health and wellbeing of all Australians from COVID‐19. An effective vaccination program is a key element required to facilitate economic recovery, safe movement throughout and beyond Australia and a return to the quality of life previously experienced.

Spatio-temporal patterns of dengue incidence in Medan City, North Sumatera, Indonesia

Dengue has been a perennial public health problem in Medan city, North Sumatera, despite the widespread implementation of dengue control. Understanding the spatial and temporal pattern of dengue is critical for effective implementation of dengue control strategies. This study aimed to characterize the epidemiology and spatio-temporal patterns of dengue in Medan City, Indonesia.
