Review of epidemics models

Ferguson's, in France[1]

Quite large amount of data on epidemics in France from Sentinel and Centre National de Reference de la Grippe, region Sud, Laboratoire de Virology.

  • workplaces not explicitly included
  • transmission rate in a household = \beta^{a}_{hous} f(t)/n, where a - age (Adult(>=18) or Child), f(t) - relative infectiousness according to time t since infection, n - the size of the household.
  • transmission rates for: within household infection (A,C), within school, within community (A->A,C->C,A<->C). Hence, the overall risk of infection includes: the household risk, the within school risk, the community risk
  • time step = 6h
  • annual variations of influenza infections modeled via: the strength of transmission during the year and the relative contribution of children to transmission during the year
