Summary
The hepatitis C virus (HCV) is a major public health problem affecting over 170 million people worldwide. In Australia an estimated 157,000 people have HCV and are at risk of serious disease, and 16,000 new infections occur each year. Treating HCV-related disease is expensive, and this healthcare burden is projected to grow significantly in coming years.

In Australia an estimated 157,000 people have HCV and are at risk of serious disease, and 16,000 new infections occur each year. Treating HCV-related disease is expensive, and this healthcare burden is projected to grow significantly in coming years. Almost all new HCV infections in Australia occur among injecting drug users (IDUs), and despite our world-leading prevention programs, the virus is spreading. Consensus is emerging that the best hope for control of HCV and related disease lies in a vaccine; our research will lay much of the groundwork for its development. The applicants' research to date shows that IDUs are being infected with HCV more frequently than previously assumed, that many carry multiple strains, and that dominant strains vary rapidly in individuals over time. These results reinforce the view that our prevention methods will not reduce infection rates and that current anti-viral treatments are not the solution. Nevertheless, we also found that some IDUs remain free of HCV infection despite risky behaviour with infected associates; intensive study of the immune functioning of these persistently non-infected individuals holds promise for vaccine development. In our proposed research, a collaboration of leading Australian epidemiologists, virologists and immunologists, we will recruit 210 young IDUs and follow them regularly for two years. Recruits will describe their social networks and nominate IDUs with whom they inject, provide blood samples and be interviewed about their behaviour at 3-month intervals. Individuals with recent and resolved HCV infection, change of dominant strain and lack of infection despite risky behaviour will be identified and their blood analysed for genetic factors that may be linked to immune protection. The outcomes will be crucial to the development and trialling of a vaccine against HCV.Read moreRead less
School Versus Community-based Albendazole Deworming For Control Of Soil Transmitted Helminths In School-age Children In The Philippines – A Cluster Randomised Controlled Trial

Summary
Intestinal parasites are a global health problem. The World Health Organization recommends regular distribution of deworming drugs, targeting school aged children. This is effective for the children receiving the drugs but does not have an impact in the wider community. We aim to determine the best strategy for delivery of deworming drugs, to achieve the maximum benefit both for children and wider community, by directly comparing the benefits of a school-targeted vs a community-mass approach.
Optimising Large-scale Public Health Interventions To Control Neglected Tropical Diseases

Summary
Neglected tropical diseases (NTD) are a group of health conditions that affect the poorest of the poor, particularly in remote and rural areas. They affect the most vulnerable communities and cause substantial, chronic health harms impairing personal and social development. Several debilitating NTD are common in remote indigenous communities and Pacific islands. I propose a series of studies to investigate new strategies to control NTD in large populations where these diseases are endemic.
Sustainable Control And Elimination Of Neglected Tropical Diseases In The Asia-Pacific

Funding Amount
$428,065.00
Summary
The neglected tropical diseases (NTDs) are of major public health importance. Parasitic worms are the most common infecting almost a third of the world’s population. Multi-component integrated intervention strategies will be required for sustainable control and elimination of NTDs in the Asia-Pacific. I will develop and lead the first Australian Centre for Population Health Research on NTDs that will undertake research into their epidemiology, control and elimination.
Innovative Approaches To Reducing The Impact Of Blood Borne Viruses And Sexually Transmitted Infections On Young People.

Funding Amount
$246,859.00
Summary
Over the next 5 years I will undertake a program of research centred on reducing the impact of blood-borne viruses (BBVs) and sexually transmitted infections (STIs) in vulnerable populations, particularly young people. I will study how these infections are transmitted, associated risk behaviours including drug and alcohol use and sexual risk, and develop interventions to improve the detection and management of infected individuals.
Minimising Infection Risks Associated With Water Exposure And With International Travel: Addressing Data Gaps To Improve Policy And Practice
Funder

Funding Amount
$401,361.00
Summary
This project will provide better understanding of health risks associated with two areas of infectious diseases: i) exposure to water, including water recycling and ii) imported infections associated with international travel. Both these issues are highly topical, and new information about exposure risks is important to help guide appropriate preventive advice.
Using Total Population Data To Describe The Characteristics Of Respiratory Infections In Order To Predict Future Epidemics And Recommend Vaccination Strategies For Western Australian Children

Summary
Respiratory infections are a major reason for children to go to hospital. I am an epidemiologist and I will be using previously collected and linked laboratory and hospital data from Western Australian children to better understand how these infections flow through the population over different seasons. I will then be able to predict future epidemics of respiratory infections and how different vaccine programs might have an impact in reducing how many children are affected by these infections.
