Human cases of arbovirus infection are monitored through the National Notifiable Diseases Surveillance System (NNDSS). States and Territories each maintain separate jurisdictional surveillance, but they all report their results, using common case definitions, to the Commonwealth Department of Health.
The diseases monitored are Ross River virus infection and Barmah Forest virus infection, Murray Valley encephalitis and kunjin, dengue, malaria and Japanese encephalitis. Notifications for each of these diseases are regularly analysed and reported in the Department's quarterly journal Communicable Diseases Intelligence.
More up-to-date statistics are available from the Communicable disease surveillance portion of the website. Complementing these data, fortnightly teleconferences by state and territory epidemiologists with their Commonwealth counterparts allow recent and local disease outbreaks to be discussed and monitored.
