Customisable parameters:

• INFECTION_RADIUS - Radius around infected person where normal person is susceptible to infection
• INFECTION_RATE - Probability that normal person will get infected when within infection radius
• NUMBALLS - Number of people
• INITIAL_INFECTED_POPULATION - Number of people infected at start of simualtion
• MAXSPEED - Maximum possible speed that people move around at (speeds and start locations are random)
• BASE_RECOVERY_TIME - Base time for recovery
• RECOVERY_TIME_RANGE - recovery_time = BASE_RECOVERY_TIME + rand(-RECOVERY_TIME_RANGE, RECOVERY_TIME_RANGE), accounts for natural variation in recovery times.
• FATALITY_RATE - Percentage of people that would die after recovery_time has elapsed. Remaining will recover.

Instructions:

1. git clone https://github.com/gursi26/pandemic_simulation.git
2. cd pandemic_simulation
3. cargo run

TODOs

• [ ] Use grid rendering system for better performance with higher number of objects
• [ ] Other, more optimised collision detection methods
• [ ] Include phenomena like
  • [ ] Social distancing
  • [ ] Lockdown with frequent trips to a central location (like a grocery store)
  • [ ] Separate communities with travel between them
  • [ ] Quarantine zones for infected patients
  • [ ] Asymptomatic cases
  • [X] Fatality rate
  • [X] Recovery rate
  • [ ] Virus mutating into a stronger variant (more contagious or more deadly)
