title: Ord River arboviruses--serological epidemiology.
abstract: This paper presents the results of haemagglutination-inhibition tests carried out on sera from 441 persons, 1,080 cattle and 335 birds in the Kimberley area. Two Alphaviruses (group A) (Ross River and Sindbis) and one Flavivirus (Murray Valley Encephalitis) were used for the preparation of haemagglutinins in the haemagglutination-inhibition tests. The tests showed a high percentage of antibody of Murray Valley Encephalitis in humans, birds and cattle, with an obvious focus of infection in the study site when cattle sera from different geographic areas were compared. These results are discussed in relation to the evolution and ecology of arboviruses in the Ord River area.
