Kermack and McKendrick

Kermack and McKendrick developed a mathematical model in the early 20th century to understand how infectious diseases spread. Their model divides a population into groups: susceptible (can catch the disease), infected (currently sick), and recovered (no longer infectious). It uses equations to describe how individuals move between these groups over time, helping to predict the outbreak's progression, peak, and decline. Their work provides a foundation for modern epidemiology, allowing health officials to analyze and control infectious diseases more effectively by understanding transmission dynamics.
