Abstract
Climate change will impact the distribution, seasonality and incidence of mosquitobornediseases. This is because climate and weather impact the distribution andbiology of mosquitoes. There is a large body of literature on vector-borne diseasedistribution and incidence in a warming climate. However, predictions are commonlymade using statistical models that contain assumptions that may not hold true in thefuture. Ross River virus infection is South Australia’s most common vector-bornedisease and the epidemiology of the disease is difficult to model because of thecomplex interplay between non-human hosts, multiple mosquito vectors, and thehuman host. Nonetheless some general projections of changes in Ross River viruscan be made. Dengue is widespread in the tropics globally and currently, withinAustralia, restricted to Queensland. The challenges of projecting changes in transmissionin future climate scenarios are discussed. I discuss the implications of climatechange for diseases already present in and potentially introduced to South Australia.
