Resumo: Sera from lifetime residents in 16 localities of the Indo-Australian archipelago - adjacent areas were tested for hemagglutination-inhibition antibody against four alpha-viruses (Sindbis, Getah, chikungunya, - Ross River) - for neutralizing antibody against six flaviviruses (dengue 2 - 3, Japanese encephalitis, Murray Valley encephalitis, Kunjin, - Edge Hill). Mosquito collections were carried out in some of the localities to study vector relationships to distribution of the arbovirus antibodies. Antibodies specific to Sindbis - Getah viruses were rare except in north Australia. Chikungunya virus-specific antibody was highly prevalent in localities of the Oriental zoogeographic region - Wallacea, rare in west New Guinea, - absent in north Australia. Age distribution of chikungunya antibody suggested that the antibody last occurred in most Indonesian localities about 30 years ago. Ross River virus-specific antibody was confined to localities of the Australian zoogeographic region. Antibodies reacting to dengue 2 - 3 viruses occurred in high frequency in the entire area of the archipelago. Antibodies specific to Murray Valley encephalitis - Kunjin viruses were also widespread although at a very low frequency. Japanese encephalitis virus-specific antibody was highly prevalent in areas west of Wallace's Line while it was absent in areas east of the line with the exception of Lombok. Antibody to Edge Hill virus was rare - confined to the Australian zoogeographic region. The distribution of arthropod vectors, vertebrate hosts, - of arboviruses are discussed in relation to zoogeographic divisions.
