Table 1 Variables used to define the age classes in the epidemic model; c = children, a = adults
From: Age-specific contacts and travel patterns in the spatial spread of 2009 H1N1 influenza pandemic
Variable | Definition |
|---|---|
α | Children fraction of the population |
q a , q c | Average number of contacts per unit time established by individuals in the children and adult classes, respectively |
η = q a /q c | Ratio of the average number of contacts |
ε = ε c α = ηε a (1 − α) | Total fraction of contacts across age classes |
r | Children fraction of the traveling population |
