Relationships between the monthly average Southern Oscillation Index (SOI) and incidences of dengue fever, Barmah Forest virus infection and Ross River virus infection in Australia, over the period 1991-2001, were studied using correlation analysis. The results showed that there were positive correlations between the monthly SOI and monthly incidence of dengue fever and Barmah Forest virus infection. No ocrrelation was found between the SOI and the incidence of Ross River virus infection over the study period. The results indicated that the SOI could be used as a warning index to explore the transmission of dengue fever and Barmah Forest virus infection over a large geographical region such as at the national level.
