Summary
Diarrhoea is a leading cause of death and disease globally, most often due to unsafe water, inadequate sanitation and poor hygiene. River water is a common water source in India, but water quality is often compromised by contamination. Riverbank Filtration technology (RBF) uses natural treatment processes to improve water quality. This project will investigate the effect of improving water quality via installation of RBF systems on diarrhoea incidence in six rural Indian communities.

Eight years into a drought Australia's water sources are becoming increasingly depleted, so we need to reduce water consumption and consider using alternative sources of water. Increased use of rainwater is one of a number of solutions available. However, current recommendations state that rainwater can be safely used for purposes other than drinking, but because of potential contamination and limited evidence regarding safety, drinking untreated rainwater is not approved by state health departments. The main outcome of this study will be to determine whether drinking untreated water from rainwater tanks poses a significant health risk. Additionally, we will determine if specific tank or maintenance characteristics can be identified that increase illness risk. The study design consists of following the health of 300 families who drink unboiled rainwater. Families will have a special tap installed that draws water through a water treatment unit (WTU). Half the families will have a working WTU and half will have a sham unit identical in appearance. The functional units sterilise water to remove any microorganisms present, while the sham filters have no effect. All participating families will keep a health diary for one year to record how often they suffer gastroenteritis. Neither the families nor the research workers will know which type of filter has been fitted. Water samples will be collected from selected households. At the end of a year the number of illnesses in the two groups will be compared. If those drinking rainwater from a sham filter suffer more often, then rainwater would be implicated as a source of gastroenteritis. This study will provide health authorities with a better understanding of the relationship between rainwater consumption and human health, and will provide data regarding safe uses of this alternative water source.Read moreRead less
Minimising Infection Risks Associated With Water Exposure And With International Travel: Addressing Data Gaps To Improve Policy And Practice

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.
Quantifying The Microbial Health Risks Of Expanded Alternative Water Use

Summary
Addressing current and future water shortages requires substitution of high quality drinking water with alternative water sources for an expanded range of purposes. However, potential adverse health effects must be avoided. This project measures health risks associated with a variety of alternative water sources and water use combinations. Project outputs will help determine appropriate requirements for water treatment and help refine guidelines to ensure that water use is safe.

Infections remain a major cause of morbidity and mortality. I will undertake research in a number of areas, with a focuses on: i)Imported infections: My lead role in and access to a global network of sites that track infections among travellers and immigrants will enable study of emerging priority issues among mobile populations. ii)Waterborne risks: I will perform studies to identify optimal strategies for improving water supply and associated health impacts in developing countries.
NHMRC Asia Pacific Centre For Innovative Dengue Prevention

Summary
World Health Organization estimates dengue incidence at around 50 million cases annually with increased frequency & severity of outbreaks in north Queensland over the last decade being mirrored around the world. The NHMRC Asia Pacific Centre for Innovative Dengue Prevention will be a world leading research facility, co-supported by Bill and Melinda Gates Foundation Grand Challenges in Global Health, focussed on the discovery and implementation of innovative methods to eliminate dengue.
Dengue, Zika and Chikungunya are viral diseases transmitted to humans by mosquitoes. Our research uses a naturally-occurring bacteria, Wolbachia, to stop mosquitoes transmitting these viruses to humans. Our proposal addresses critical knowledge gaps in the biology of mosquitoes and Wolbachia to enable large-scale field-deployment optimisation in affected countries. The outcome of our research will immediately translate to disease control efforts in northern Australia, Asia and Latin America.

At a broader scale, an estimated 2.5 billion people live in areas at risk of epidemic Dengue transmission. Chemical insecticides are the mainstay of current mosquito control throughout many parts of the world. However, problems of insecticide resistance, environmental contamination and risks to human health, mean that chemical pesticides have not provided a universal solution, either as outdoor sprays, residual house sprays or as insecticide treated nets. This creates a pressing need for practical alternatives. Building on approaches and technologies developed for control of locusts in Australia and Africa, we have recently discovered that the ability of mosquitoes to transmit malaria can be substantially reduced with insect fungal pathogens used as biological pesticides. We found that exposure to biopesticide-treated surfaces reduced the number of mosquitoes able to transmit malaria 80-fold. Other supporting data from semi-field trials confirm the feasibility of infecting mosquitoes under real field conditions. Together, these results represent a significant advance in the development of a cheap and sustainable biological alternative to chemical insecticides for disease control. We now wish to extend this research to explore the potential for use of fungal pathogens in control of mosquito-borne viruses. Preliminary studies already confirm that we can infect the key mosquito species responsible for transmitting Dengue. The aim of the current project is to conduct a more comprehensive evaluation of a wider range of fungal isolates to identify strains with the greatest potential to stop transmission of mosquito-borne viruses. The longer term goal is to translate this research into a practical product. Such a product would offer a cheap, environmentally friendly disease control measure, with reduced potential for resistance evolution.Read moreRead less
Integration And Expansion Of A Sentinel Surveillance System To Improve Infectious Disease Outcomes For Indigenous Australians; The ATLAS Network

Summary
Infectious diseases remain a significant health issue for Indigenous Australians. Our proposal is to extend a sentinel surveillance network operating in 32 Aboriginal primary care services, with a focus on sexually transmissible infections and blood borne virsuses. By expanding, we will increase the number of sites, and add vaccine preventable diseases to the network. In doing this, we move from a surveillance system to a research network that can inform health service strategies and practice.
