Introduction
The study of how diseases spread, especially after the Covid-19
pandemic, has grabbed a lot of attention. While most focus has
been on picking the right model to understand and predict how
diseases spread, there's still a lot we can learn by digging deeper
into the hidden dynamics. This study offers that models can be
improved by using triangular probabilistic distributions as
distributed delays.

Optimization
Determination of Triangular Parameters
Parameters of Triangular Distribution
T = {x0, c,L | x0 ∈ Z +, c ∈ Z +,L ∈ Z +}
x0 : time delay or the starting point (ta) of the triangular
distribution,
c : mode of the triangular distribution,
L: period of the triangular distribution.
Parameters of Triangular Distribution
Germany, optimized in short period
Parameters of Triangular Distribution
S. Korea, optimized in short period
