I refer to J.H. Jones’ Notes on R0. Preliminaries The standard SIR model consists of a system of three differential equations ds/dt = -βsi di/dt = βsi – νi dr/dt = νi for the fractions s, i, r of susceptible, infected, and recovered (removed) individuals, dt = 1 day. β is the infection rate, i.e. […]

- Tags 'Infected', and recovered (removed) individuals, at least when a reduction of the duration of infectiousness is not at sight. To estimate the impact of a mitigation measure on the infection, being defined as the reciprocal of the duration of infectiousness di (measured in days), dt = 1 day. β is the infection rate, i, I refer to J.H. Jones' Notes on R0. Preliminaries The standard SIR model consists of a system of three differential equations ds/dt = -βsi, i.e. R = β · di To reduce the growth of spreading of a disease, i.e. the number of individuals an infected indiviual infects per day, i.e. ν = 1/di. The reproduction number R is the product of infection rate and duration of infectiousness, it is worth to consider it as the product of several factors, mitigation measures typically target at the infection rate, r$ of susceptible, ν is the removal rate
