The military infirmary 3rd class at Menado (Minahasa) is mentioned in the publication of D. Schoute “De Geneeskunde in Nederlandsch-Indie in de 19e eeuw”, GTNI 75 (1935) 10, 827. The article refers to a survey of  all the military facilities in 1867 . In that year the infirmary at Manado had on average 10 inpatients. The infirmary was part of the Military Medical Service (MGD),  which in 1867 (the year of the survey of all military facilities) managed a total of 79 facilities (3 large military hospitals, 35 garrison hospitals and 41 infirmaries) with on average 4,244 occupied beds. Some 25 years later, the Annex D of the Koloniaal Verslag 1890 reports a total  of 3,358 inpatients by the end of that year, whereas 52,631 patients have been admitted for the whole of the Netherlands Indies. The report concerns 28 military hospitals, 54 ziekenzalen (infirmaries) and 6 specialized facilities. The average occupation rate of the Manado infirmery is then 10 inpatients, whereas 60 have been admitted that year. The situation by the end of the year 1890 is a presence of 3 patients. In 1899 the situation of military health facilities was: 30 hospitals, 56 infirmaries and 5 specialized facilities, such as reconvalescent centers and leprosy asylums. The total number of admittances was in 1899: 57,071 and the number of present inpatients by the end of 1899: 3,731. These figures were for the Manado infirmery: 19 admittances and on 31 December 1899 no patients were present. (See Koloniaal Verslag 1900, Addendum A).

Manado is in the 1930s a Residency and department, subdepartment and district with a capital of the same name. Only the departments Manado and Gorontalo are directly ruled, the other parts of the region exist out of selfgoverning Landscapes. The whole region is mountaneous and has still working volcanoes. The town of Manado itself had 27,500 inhabitants of whom 1,400 Europeans and 6,000 Chinese. It has a municipality council, which is chaired by a mayor. Manado is part of the Minahasa region. Its population is together with that of the Sangihe and Talud islands almost entirely Christian (Gonggryp 1934, 806-810).
