 A population of N = 100,000 inhabitants of Germany is subdivided according to age a and risk category r. We assume that all age groups are fully susceptible at begin of the outbreak. A fraction of F
_{
a
}= 6% of all children (age < 20 years) are regarded as being under high risk (r = r
_{1}) after an influenza infection whereby the remaining 94% are under low risk (r = r
_{2}). The high risk fractions of working adults (ages 20–59) and elderly (ages 60+) are F
_{
a
}= 14% and F
_{
a
}= 47%, respectively. Source: [9]
