Prevention and control of infections and contagious diseases are the foundations of all public health measures. There are three key factors in the control of communicable disease are as follows:
*The removal, elimination or containment of the cause or source of infection
*The disruption and blockage of the chain of disease transmission
*The protection of the susceptible population from infection and disease
The goal of prevention and control programs is to reduce the prevalence of a disease to a level at which it no longer poses a major public health problem.
The methods of prevention and control are used in several fronts. The first front is the environment, the second is the person at risk and the third front is the population or community.
Immunization is one of the most accepted and cost-effective preventive health practices in the United States. Since the 1950s, vaccines have prevented countless days of illness and hundreds of thousands of deaths.
