Abstract
Human pathogens transmitted by mosquitoes pose a
significant threat to population health in New South
Wales. Within the State, there is annual activity of Ross
River virus and Barmah Forest virus, occasional activity
from Kunjin virus and Sindbis virus, and rare epidemics
of Murray Valley encephalitis virus. For the traveller,
dengue and malaria are constant threats. The focus of this
article will be the mosquito-borne viruses (the
‘arboviruses’), including the factors that influence their
activity in New South Wales, how they affect the
community, and the future threats they pose to population
health in the State.
