Excerpt from A Manual of Hygiene and Sanitation The preceding paragraph indicates the individual or personal aspect that marked the common concept of the subject until a comparatively short time ago. More recently the tendency is also to view its func tions, opportunities and problems from a social and altruistic stand-point, and the field has so enlarged in this direction that it is questionable whether it may not be better to supplant the older word - Hygiene when used to refer to the general science, with the newer term - Public Health and Preventive Medicine. But, after all, he who works to improve the sanitary condition of his neighbors and his neighborhood, no matter how extensive these may be in numbers and area, at the same time well serves his own interests, for not only is disease no respecter of persons, but its transmission and dis semination depend very much upon one's relationships with others.
