It’s a common misconception, but the S curve generated by disease, for example, with exponential growth at the beginning, corresponds not to the normal distribution, but the logistic distribution, which has fatter tails than the normal. The bell curve drops to zero with exp(-x^2), that is extremely fast. The logistic distribution (derivative of the S-curve described here) drops to zero with exp(-|x|), that is exponentially, but not as fast as the normal distribution. https://en.wikipedia.org/wiki/Logistic_distribution https://en.wikipedia.org/wiki/Logistic_distribution
