^¶The probability parameter values are varied by ±25%.

^§Selection of distributions for each parameter are believed to be the best practice. Beta distribution is best used for probability value due to its properties, which ranges from 0 to 1.

The probability of asymptomatic equals to one minus the probability of symptomatic cases.
