Control of Harmful Micro-organisms

Better health can be achieved basically by controlling disease-causing micro-organisms and their animal vectors and also by improving health facilities.

Micro-organisms can be controlled in the following ways:

  1. Use of High Temperature: This involves sterilization by boiling, autoclaving or heating of food and other products to kill disease causing organisms.
  2. Preserving Food by Salting: This is the application of salt in food to kill micro- organisms or render them inactive
  3. Uses of Drugs/Antibiotics: Many diseases can be controlled through the use of drugs and antibiotics in order to kill the causative micro- organisms. Fansid is used to kill malaria.
  4. Immunization or Rascination: Immunization is the process by which a healthy person is inoculated with a preparation of a mild form of the pathogen.
