Flu trends and forecast
Flu calls typically stay low during the summer months and rise to moderate or high at the peak of flu season. The trend is only intense in years of unusual flu activity, such as in 2009 when a new strain of influenza emerged.
When the blue line is within the grey shaded area in the below graph, it's a typical flu season. If the blue line rises above the shaded area this may be the first sign of an increase in flu-like illness in Australia.
