From: Comparing large-scale computational approaches to epidemic modeling: Agent-based versus structured metapopulation models

Model parameters

GLEaM

Agent-based

Initial conditions

Origin of pandemic

Hanoi

Hanoi

Arrival of infection in country

Simulating global pandemic

Provided by GLEaM

Transmission dynamics (common to both models)

Basic reproductive ratio, R 0

1.9 [1.5, 2.3]

Average latency period, ε-1

2.0 days

Average infectious period, μ-1

3.0 days

Probability of asymptomatic disease, p a

33%

Reduction in disease transmission due to asymptomatic disease, r β

50%

Mobility

Long/short range travel

Explicit air travel with 70% daily average occupancy of flights.

Commuting model used for geographically locating schools and workplaces.

 

Implicit commuting through effective force of infection with τ = 3 day-1 return rate and real commuting fluxes.

Implicit within country through random contacts in the general population.

Impact of symptomatic disease on individual behaviour

Stop travelling when ill with probability 1-p t = 50%

Reduction in school and work attendance, ranging from 90% in daycare centers to 50% in workplaces.

  1. Model assumptions and parameter values used as baseline [and sensitivity analysis] are summarized both for GLEaM and the agent-based model.
