Public health care service was organized anew by the Austrian Medical Act in 1870. On the basis of this act, countries issued regional acts for arrangement of health service in municipalities. Concern for human health was one of the tasks of municipalities. Health care service in municipalities was performed by doctors (county, district, and municipal) and ancillary health care (district nurses, midwives, hospital attendants). Until the end of 1912, Dr Josef Marcius, who received wages of 1960 K, was the district doctor (for entire Trbovlje municipality, Dol municipality, and cadastral municipalities Marna, Sv. Štefan, and Sv. Jedert), on 1 January 1913 replaced by municipal doctor Dr Anton Jamar. Midwives provided assistance in childbirth. Midwives had to keep a journal or record of childbirths (childbirth report) and provide the official doctor with access to it. In 1920, 14 midwives performed the delivery in political district Brežice. Municipalities were particularly sensitive to infectious diseases. On the outbreak of infectious diseases (scarlatina, diphtheria, typhoid, torticollis, measles, smallpox, dysentery etc.) and against the spreading of the diseases, midwives were obligated to follow general instructions issued by the District Board Celje for the territory of its medical district (parboiling objects in lye, disinfection with the solution of Lysol, carbolic solution, lime milk or quicklime, boiling water, room disinfection ...). Isolated houses were also important to prevent the spread of an infectious disease among citizens as isolation of a patient proved to be a successful preventive measure. This is the reason for the decision of municipality of Trbovlje to build a new isolated house in 1895 on the plot no. 294 of cadastral municipality Trbovlje. The building was completed in January 1896 and could take up to 30 patients. Preventive inoculations of children and adults were effective protection against infectious diseases were. Municipality had to prepare a special room and set a date of implementation of vaccination, which was then carried out by a competent doctor who was required to keep a journal of vaccination. To maintain cleanliness of workers’ housing, municipalities performed sanitary inspections, strived to acquire new outpatient premises and hospitals, and took care of the payment for patient care in public hospitals if patients or their family could not afford to pay the bills. Preserved archival material in the fonds of administrative authorities functioning from the 19th century to 1941 in the area of Historical Archives Celje presents an important source for studying health care activities during that period. Because the documents were established in administrative operation among administrative authorities and health care providers on the field, textual records are predominant (minutes, reports, statistical records, statements, journals of performed tasks etc.), and also building plans or photos as annexes to textual records.
