What is public health, and why does it matter?
Public health is a very broad subject. In general, it refers to the study of population disease, trends, and various ways to implement broad prevention strategies. The reason that public health matters so much is that the best way to treat something is to prevent it from happening in the first place. That is where public health comes in.
