A simple simulator for the transmission of human diseases and viruses.
Caution: This is a simulation only based on a simple model. It's not virological/medical proofed
The simulation uses a chess board like setup. In each cell is an individual. It can move by random in a defined area and if infected can infect other individuals. Some infected individuals will show heavy symptoms.
Some assumptions:
- individuals which show symptoms behave rational and will not infect other individuals
- The durations of the infections are average durations and are the same for all individuals.

The simulation will show 3 diagrams
- Heatmap: The heatmap is based on 100 squares in x direction. Each square repesents x individuals (for example 25 = 5*5 when x-size is configured to 500) and the colors represent the number of infected individuals.
- Totals: The numbers per day of total infected, the percentage of infected, new infected, cured, ...
- Histogram: Shows for each count of infected individuals the number of squares
The simulation can be startet, stopped, paused, continued and can run for a single day. When paused, the simulation can be reconfigured to show effects due to changes in the behaviour of the individuals. This could bee reducing the mobility, reducing the number of contacts, reducing the propability to infect others
There are several possibilities to configure the simulator
Configure the number of people on a chessboard like setup, the simulation period and the initial number of infected individuals. The individuals will be located randomized on the board.
| Field | Description |
|---|---|
| X-Size | The width of the area |
| Y-Size | The heigh of the area |
| Simulation period (days) | The duration of the simulation in days |
| Initially infected | The number of individuals which are initially |
Configure the behaviour of the disease/virus.
| Field | Description |
|---|---|
| Resistant (%) | Percentage of individuals which are resistant against the diseae/virus |
| No symptoms (%) | Percentage of infected individuals which do not show any symptoms, so do not know that they are infected |
| Heavy symptoms (%) | Percentage of infected indifiduals which will have heayy symptoms |
| Days not infectious | The number of days after the infection until an infected individual can transfer the disease/virus to other individuals |
| Days infectious | Number of days the infected individuals are infectious |
| Days symptoms | Number of days the infectedt individuals show symptoms |
Configure the personal behaviour of the individuals
| Field | Description |
|---|---|
| Moving distance | The distance individuals move to left/right up/down |
| Far travel ratio | The percentage of far travels beyond the moving distance |
| Daily contacts | The number of daly contacts |
| Infection rate (%) | The percentage of individuals infected by a contact to another infected individual. |
