Parameters used in simulating the epidemics in this study. Catastrophic flu infects about 50% of the population, while strong, mildly strong, and mild flu infect approximately 30%, 20% and 10% of the population respectively. Each infected individual has a randomly assigned probability of having a specific incubation or infectious duration. For example, for catastrophic flu, each infected individual have a probability of 0.3, 0.5 or 0.2 of having an incubation period duration of 1, 2, or 3 days respectively.
