Table 1 Model parameters
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. |
| Â | Implicit commuting through effective force of infection with Ï„ = 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. |
