Figure 6 is a line graph showing the national percentage of participants who had two or more days off work or normal duties due to fever and cough compared with the national percentage of participants who sought medical advice from a general practitioner, emergency department or as a hospital inpatient each week (ending Sunday) from 2011 to 2015. The number of weekly participants is used as denominator for all percentages. There were similar percentages of participants taking time off work or normal duties in 2015 compared to 2014 (peak level of 2.3% in 2014 compared to a peak level of 2.5% in 2014) and the same percentage of participants seeking health advice in both 2014 and 2015 (peak level of 1.6%).
