Towards prediction and surveillance of Murray Valley encephalitis activity in Australia.

Current practices for early warning of activity of Murray Valley encephalitis and other medically-important arboviruses are reviewed with view to improvement. Data from previous papers on Culex annulirostris populations, environmental factors and virus infection rates were reanalysed and the results considered as a basis for prediction and surveillance. This goal will only be achieved with improved national cooperation, a better epidemiological understanding and greater knowledge of the bionomics of the major vector, Culex annulirostris. The improved monitoring system will utilize meteorological, serological and entomological criteria.
