Case 3: Role of age on the first-time effect of COVID-19.
It has also been reported and is widely accepted that people of old age are affected more severely by the COVID-19 as compared to the younger population. This situation is also modeled by the Quantum Perturbation theory. However, the reverse Quantum Perturbation effect applies to this scenario in which the unperturbed term represents the effect of COVID-19 on the old people above the age of 80. The first-order correction to energy term represents the next lower age population and so on. The lower effect of COVID-19 on young age people could be attributed to their immunity, which decreases in strength with age, keeping all other factors the same. Mathematically, the varying effect with age is given by the following equations.
The effect of COVID-19 on very old age people is represented by the unperturbed energy termEn(0). The effect on the next lower age group is modeled by the first-order energy correction term given as
