I reflect on my past experiences with event-based simulation, connecting it to Queuing Theory and the statistical mathematics used in telephone exchanges and modern technological applications, particularly gaming platforms like Zwift. I draw parallels between call arrival patterns and infection models, particularly regarding COVID-19. I acknowledge the influence of historical research, including work by Prof. Neil Ferguson, on understanding infection dynamics and the necessity for public health measures like social distancing. I emphasize the importance of mathematical modeling in managing infectious diseases effectively.
