R represents the effective reproductive number (R) of influenza within a workplace. This is the average number of secondary cases generated per primary case during the infectious period. The age-stratified serologically confirmed influenza attack rates assumed for the above scenarios are: 6.6% (95% CI: 3.2%-10.0%) for employees age 18-64 and 9.0% (95% CI: 4.2%-13.8%) for employees over the age of 65.
