Each patient is infectious rate to the effective contact rate of susceptible person S.It is passed in t moment, unit interval by all patients
The number (i.e. newly-increased patient's number) of dye is the incidence of disease.It is assumed that contact rate is directly proportional to population in system, i.e. U=
KN, t moment effective contact rate are β N=β 0kN, and β=β 0k are ratio of the effective contact rate in total population N in formula, that is, are known as passing
Contaminate rate coefficient.When effective contact rate is β N, incidence is β SI, i.e., is β SI in the moment t new patient's numbers generated, it represents easy
New patient's number caused by being contacted between sense person S and patient I.This incidence is bilinearity incidence (bilinear), also referred to as
Simple mass action law.
When the size of population is larger, contact rate is proportional to population clearly unpractical, because a patient is in list
The people of position time interior energy contact is limited.Contact rate is generally assumed that at this time as a constant k, then effective contact rate is β=β
0k, and the incidence of disease is just β SI/N, such incidence is known as Standard Incidence Ratio.
There is researcher to point out, for the mankind and some social animals, Standard Incidence Ratio is more more scientific than bilinearity incidence.
So many models are corrected on the basis of Standard Incidence Ratio.Someone has studied the cholera disease of several Nonlinear incidence rates
The kinetic model that poison is propagated.However, these kinetic models can not really reflect the detailed process of infectious disease transmission, because
It is determined for incidence by many factors, being at any time can be changed.
