Prevention of Communicable Diseases
Communicable disease transmission is a dynamic process. The process is dependent on the following:
Interaction of the agent (microorganism) the host (person), and the environment (conditions present).
In order for a communicable disease to occur the following factors must be present:
a. A microorganism of sufficient strength (virulence)
b. A person who is susceptible (lowered immunity)
c. An environment supportive to the agent’s transmission
Types of Transmission:
Direct Transmission – occurs when an infectious agent enters a receptive portal, i.e., through direct contact as: touching, kissing, biting, or projecting air droplets by sneezing, talking, spitting, coughing.
Indirect Transmission – occurs when an infectious agent is deposited on contaminated objects or materials, i.e., toys, soiled clothes, bedding, cooking or eating utensils, food, water.
