seairmobility: Mobility-Based SEAIR Epidemic Models
Tools for simulating, analysing, and fitting mobility-based
SEAIR (Susceptible-Exposed-Asymptomatic-Infectious-Recovered)
compartmental epidemic models with heterogeneous individual
mobility. Each individual carries a fixed mobility trait that
scales susceptibility and infectiousness through a rank-one
kernel, extending the mobility-based compartmental framework of
Jiang et al. (2025) <doi:10.1137/24M1691557> by adding a latent
stage and a behavioural split between asymptomatic and symptomatic
infectiousness. Provides a numerical solver for the underlying
partial differential equation system, closed-form computation of
the basic reproduction number R0 and the final epidemic size, and
a parametric least-squares routine for recovering the mobility
distribution from an observed aggregate symptomatic time series.
