HIST 249 Lecture Notes - Lecture 23: Sexually Transmitted Infection, Radiography, Alcoholism
Document Summary
Public health has a very wide scope ranging from epidemic diseases, environmental pollution, diseases related to social conditions etc. There has been a consistent tendency to expand the scope of public health and shift focus without abandoning earlier roles but not all roles are equal. > lecture slides. The targets and focus of public health has shifted not that earlier roles like sanitation have been abandoned but there has been additions of new tasks to the old tasks. Roles change in terms of their importance as new roles take on prominence. In the early 19th century the main goal of public health was largely sanitation. This was not abandoned but in the late 19th early 20th centuries bacteriology emerged (targeting microorganisms and the vectors in a way that made public health much more focused and targeted) Since it involves making people do things they wouldn"t do by themselves. Ideas about causation determine blueprints for public health action and activity.
