It can be divided into four patterns according to the change over time in the number of confirmed COVID-19 infections per day.

Pattern A: Epidemic growth is exponential. Indicates that there are no restrictions such as restrictions on going out, or that restrictions are insufficient. Many deaths are recorded until a collective immunity is obtained.

Pattern B: Lockdown and other controls are partially or incompletely enforced. It is also possible that the first and second waves overlap. If behavior restriction is released in this state, it may become pattern A. The longer the time, the greater the economic damage.

Pattern C: Lockdown and other controls are running very efficiently. Even if the next wave comes, you can calm down by repeating the same measures. This pattern can also be obtained by intentional manipulation of the number of inspections.

Pattern D: Indicates that the epidemic has temporarily stopped. However, there is a second wave risk due to the influx of infected people from the outside. A similar number of infections occurs when the antibody of a previously infected individual decreases.
