Figure 6 is a line graph showing the national proportion of participants with ILI (defined as fever and cough) compared with counts of national influenza laboratory notifications for each week ending Sunday from 2007 to 2014. A similar seasonality pattern is seen in both the Flutracking ILI data and confirmed influenza notifications, with Flutracking ILI activity peaking up to four weeks earlier than confirmed influenza notfications in all years, except 2011 where confirmed influenza notifications peaked one week earlier than Flutracking ILI activity. There was an increase in the number of laboratory confirmed cases of influenza from 2,381 notifications in the peak week of 2013 to 7,170 notifications in the peak week of 2014. The peak weekly ILI prevalence for 2014 Flutracking data unstratified by vaccination status was also higher (4.7%) than the peak weekly prevalence for 2013 (3.6%).
