Adjusted relations between the monthly incidence rates of notified Ross River virus and climatic variables*
| Model I | Model II | |||
|---|---|---|---|---|
| Climate variable | β | 95% CI | β | 95% CI |
| *Maximum and minimum temperature at a lag of three months were included in Model I and Model II, respectively. Rainfall at a lag of two months, tidal level in the current month and relative humidity at a lag of two months were used in the models. A lag of time is defined as the time span between two observations. The variables adjusted for included autoregressive variable, moving average factor, seasonality, and the year when the case was notified. | ||||
