Interactive SIR Model with Real-time Visualization
The average number of people one infected person will infect. R₀ > 1 means the epidemic grows, R₀ < 1 means it declines.
How quickly infected people recover. Higher values mean shorter infection periods and faster epidemic progression.
Masks reduce transmission by blocking respiratory droplets. High compliance significantly flattens the epidemic curve.
Vaccination creates immunity without infection, reducing the susceptible population and achieving herd immunity faster.
