Table 2. The distribution of the sojourn time in class r determines the oscillation of MP epidemics.
| Distribution of sojourn time in the class e | Distribution of sojourn time in the class i | Distribution of sojourn time in the class r | Oscillation | |
|---|---|---|---|---|
| Scenario 1 | Exponential | Exponential | Exponential | No oscillation |
| Scenario 2 | Delta | Exponential | Exponential | No oscillation |
| Scenario 3 | Exponential | Delta | Exponential | No oscillation |
| Scenario 4 | Delta | Delta | Exponential | No oscillation |
| Scenario 5 | Exponential | Exponential | Delta | Oscillate |
| Scenario 6 | Delta | Exponential | Delta | Oscillate |
| Scenario 7 | Exponential | Delta | Delta | Oscillate |
| Scenario 8 | Delta | Delta | Delta | Oscillate |
“Exponential” denotes exponential distribution and “Delta” denotes delta distribution.
