About 14,000 cases of bowel cancer occur annually in Australia despite the availability of life-saving screening. Most people do not receive recommended screening colonoscopy. We will look at why people at high-risk avoid screening and why people at average risk seek unnecessary screening. We will analyse family history and contacts with the healthcare system that impact screening decisions. We will determine the impact of screening on reducing the number of new cases and deaths.

A range of programs, such as vaccination schedules and intervention in outbreaks, is in place to reduce our burden of illness from infectious diseases. This project aims to develop new methods, based on models and associated statistical analyses, to help ensure that our control programs are based on the best available evidence.

This project aims to develop new methods, based on models and associated statistical analyses, to help ensure that our control programs are based on the best available evidence. There are five specific themes: 1. Developed methods for predicting major outbreaks of diseases and appy them to Australian data on measles, pertussis and Ross River virus. The new methods will enable timely intervention to reduce the population risk from these diseases, and to guide the proposed elimination of measles from Australia. 2. The current concept of vaccine efficacy, which is central to the epidemiological assessment of vaccines, performs poorly when the vaccine provides only partial protection, when immunity wanes over time and when infected vaccinees have a lower infectivity. A concept of vaccine efficacy will be developed that overcomes these weaknesses. This concept will find widespread use in epidemiology. 3. Data available from 80 outbreak investigations of transmissible diseases will be analysed to assess the relative effectiveness of various intervention steps. 4. A comprehensive model, and associated computer software, will be developed as a tool for assessing the relative merits of different vaccination schedules. It will be applied to address Australian policy issues for vaccination against pertussis, chickenpox and rubella. 5. The method of backprojection for estimating trends in HIV infection and predicting AIDS incidence will be enhanced to incorporate newly available data in which HIV and AIDS diagnoses are linked. This will enable a precise assessment of infection incidence among heterosexuals and other exposure categories with relatively few cases, to ensure that HIV does not spread more widely.Read moreRead less
HIV Pre-exposure Prophylaxis In Men Who Have Sex With Men: Investigating Impacts On HIV Incidence And Novel Methods Of Engagement

Summary
HIV infections are increasing in gay men and other men who have sex with men (MSM) in Australia and Indonesia. A promising new HIV prevention strategy is HIV pre-exposure prophylaxis (PrEP), which involves HIV-negative individuals taking one pill containing HIV treatments per day to prevent infection. PrEP is highly effective when taken correctly. Access to PrEP is currently very limited. Studies to investigate the best ways to implement PrEP services are required in Australia and Indonesia.
