Pathogenicity

Infection and Transmission

The infections are generated by the pathogenic organisms present in the environment. They maintain the capacity to invade a host body and establish colonies. A disease caused by such infectious agents is called a communicable disease or transmissible disease. These diseases spread through diverse means including blood, food, water, air, or vectors.
