DESCRIPTION

Managing the threats of mosquito-borne disease in Australia requires an understanding of mosquito populations as well as their associations with local wetlands and wildlife. Urban planning can play a role too in exposing the community to increased mosquito risk and predisposing urban environments to the introduction of exotic mosquitoes. This presentation provides key slides included in the talk titled "Reducing the burden of endemic vector-borne disease in Australia: The role of urban planing, wetland rehabilitation and wildlife conservation" given at the Marie Bashir Institute for Infectious Diseases and Biosecurity 2014 Colloquium, 25 November 2014. http://sydney.edu.au/mbi/news/2014/2014-colloquium.php
