Number of in-patients

The number of in-patients is the sum of patients which changed not only by the newly diagnosed hospitalized and those who died among in-patients, by other factors such as the number of patients who escaped or were discharged, depending on the condition of the times. Recently, they were encouraged to be discharged, but the long period of the segregation policy causing leprosy stigma might influence the number of those who went into the society.
