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 model: probability of the infection of the individual i, , where is the instantaneous infection risk of the individual i.
- transmission rate in a household , 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 (included in ), where y - year
Ferguson's, in UK and USA[2]
- households, schools, workplaces included in the model
- commuting data also included (the average distances traveled from hh to wp); the UK distance distribution more-less like power law, that of USA - surprisingly a bit different
- air travel data included
- time step = 6h
- transmission model: probability of the infection of the individual i, , where is the instantaneous infection risk of the individual i.
Ferguson's, in Thailand[3]
- households, schools, workplaces included in the model
- travel data - not enormous, but some, generalized into probabilities of commuting within district
- seasonality not included (available data suggested that climate changes do not influence the infectivity rate)
Ferguson's in UK[4]
Dunham's general model - MASON[5]
Germann's, in USA[6]
Stroud's, in southern California, USA[7]
