This chapter summarises the standpoint of public health administration the question of the institutional treatment of phthisis. The training of the early patient, when it can be secured, holds good during a longer period of infectivity than that of the intermediate or advanced patient. No charge is made for the admission of the municipal patients, who are chiefly labourers, artisans, clerks, and their relatives. The isolation hospital consists of four main pavilions for infectious cases such as an administrative block, the borough disinfecting station, a laundry, and a small destructor. Infection might be spread in any of the following ways: by contact between patients; by the carriage of infection by nurses, or by the doctors; by infection from the laundry or kitchen. The consumptive patients are visited first, and overalls are used when going into the other wards. People at the working years of life are those who can derive the greatest benefit from the sanatorium treatment and training.
