What are the future endemic & exotic mosquito-borne disease threats to Australia? Dr. Cameron Webb Department of Medical Entomology Marie Bashir Institute of Infectious Disease & Biosecurity, University of Sydney & Pathology West – ICPMR Westmead Westmead Hospital, Westmead NSW 2145 @mozziebites
What will drive future risks of mosquito-borne disease in Australia? Climate? Urbanisation? Wetland conservation? Globalisation?

Future mosquito-borne disease risk will be determined by more than just temperature, tides and rainfall Drivers of outbreaks may include wildlife conservation, wetland rehabilitation, urban development & mosquito control activities
Dengue is quickly becoming the most important mosquitoborne disease globally 1. 2. 1. http://www.themalaymailonline.com/malaysia/article/teng-selangor-to-cooperate-with-health-ministry-to-address-dengue 2. http://www.abc.net.au/news/2014-02-12/an-malaysia-warns-of-spike-in-dengue-fever-cases/5254086
Dengue is an increasing threat to Australia Future risk determined by distribution of suitable vector/s and importation of pathogens
Human movement has been, and will continue to be, one of the most important factors driving new vector and pathogen activity
Rates of mosquito-borne infections in returning Australian travellers have steadily increased since 1991 Knope et al. 2013. Increasing notifications of dengue in Australia related to overseas travel 1991-2012. CDI 37: 55-59
The Asian Tiger Mosquito has benefited from international trade and travel and is now found pretty much everywhere except mainland Australia… Benedict et al. 2007.

Can we vaccinate mosquitoes against dengue? (or use other high tech solutions to control mosquitoes or the spread of viruses?) www.eliminatedengue.com
What does all this mean? When it comes to the future risk of mosquito-borne disease in Australia, perhaps the climate change debate is a distraction from what we need. Surveillance. Management. Education. www.cameronwebb.wordpress.com/ @mozziebites
