Summary

Infection during transport can sustain diseases in multiple locations and increase prevalence. Exit screening can help manage disease spread, with mass action incidence potentially raising prevalence more than standard incidence.

Area of Science:

  • Epidemiology
  • Mathematical Biology
  • Infectious Disease Dynamics

Background:

  • Susceptible-Infectious-Susceptible (SIS) models are crucial for understanding disease spread.
  • Parameter heterogeneity can significantly impact epidemic dynamics.
  • Infection during travel between populations is a key factor in disease transmission.

Purpose of the Study:

  • To analyze a two-patch SIS model incorporating parameter heterogeneity and travel-related infections.
  • To investigate the global stability of disease-free and endemic equilibria.
  • To evaluate the impact of unilateral exit screening and different incidence functions on disease persistence and prevalence.

Main Methods:

  • Development and analysis of a two-patch SIS epidemic model.
  • Mathematical proofs for global asymptotic stability of equilibria based on the basic reproduction number.
  • Numerical simulations to compare incidence functions (mass action vs. standard) and screening strategies.

Main Results:

  • Parameter heterogeneity and infection during transport increase the likelihood of disease persistence across patches.
  • Infection during transport amplifies disease prevalence when the disease is established.
  • Mass action incidence for travel-related infections leads to higher disease prevalence compared to standard incidence.

Conclusions:

  • Travel-associated infections are critical drivers of epidemic persistence and intensity in metapopulation models.
  • Exit screening effectiveness depends on implementation, and incidence function choice significantly alters predicted prevalence.
  • The study highlights the importance of considering travel dynamics and incidence types in epidemic control strategies.
