Indicator | Parameters | Calculation |
Transmissibility | syndromic ILI | Number of notified ILI cases*100/Total of outpatients (a) (a) = Proportion of notified ILI cases |
virological ILI | Number of positive ILI cases*100/Total of tested ILI cases (b) (b) = Positivity rate of ILI cases | |
Composite ILI or product of syndromic and virological ILI | Proportion of notified ILI cases*Positivity rate of ILI cases {(a)*(b)} |
