Management of the Causative Agent/Factor or Its Vector
The most direct method of controlling a disease is to eliminate its cause. The basic requirements for management through affecting the agent directly are, first, a knowledge of the identity of the cause and, secondly, some method for its reduction or elimination. The simplest method of eliminating a causative factor is to prevent the introduction of new disease agents into areas where they currently do not exist. This form of disease prevention usually involves restricting or modifying human activities, rather than physically barring entry of the agent, and it will be discussed in Chapter 15, together with other methods based on influencing human activities.
