This sanitary code is based on the concept of controlling and changing the physical environments so as to protect and improve the public health. Certain types of illness may be prevalent where living conditions place dependence on common water supplies and on others for food and drink, where vermin abound, where disposal of body wastes endanger others, and where filth in general abounds. Such conditions perpetuate disease and may set into action a series of events that result in epidemics. Methods have been developed to deal competently with conditions promoting the transmission of disease. It is hereby declared to be the duty of the board of health to deal with forces and processes of the environment and to influence or control them in the interest of health, individual and community alike, to prevent the outbreak and spread of dangerous, contagious and infectious disease.
