This list shows the parameters that are applied when spawning a simulation without additional arguments like sim = Simulation().
The config can be found here.
| Parameter | Value |
|---|
| Time Unit | days |

| Start date | 2024-01-01 |
| End date | 2024-12-31 |
| Start condition | 0.1% randomly infected individuals (called InfectedFraction) |
| Stop criterion | TimesUp, the simulation ends after 365 days |
| Parameter | Value |
|---|
| Size | 100,000 individuals |
| Average household size | 3 individuals |
| Average office size | 5 individuals (everybody 18-65 years assigned) |
| Average school size | 100 individuals (everybody 6-18 years assigned); internally handled as SchoolClass |
| Parameter | Value |
|---|
| Number of Pathogens | 1 |
| Name | Covid19 |
| Transmission rate | 20% infection chance for each contact, given as transmission_rate |
| Infectiousness profile | ConstantInfectiousness (no changes between days, set to 100% each day) |
| Progression assignment | Stratified by age groups (-14, 15-65, 66-) across 4 categories (Asymptomatic, Mild, Severe, Critical) |
| Immunity profile | FullImmunity (a person is fully immune after the first infection) |
Disease Progression (This is part of the pathogen and only separated for readability.)

| Parameter | Value |
|---|
| Sampling Type | ContactparameterSampling for all settings |
| Base Setting contact rate | 1 contact per day (poisson distributed), randomly drawn from member list |
| Any other setting | If you load a population model with more setting types, they will have the same parameters |
