This process, called the chain of infection, can only occur when all six links in the chain are intact. Susceptibility of a host depends on genetic or constitutional factors, specific immunity, and nonspecific factors that affect an individual’s ability to resist infection or to limit pathogenicity. In this ‘sequence’, all elements must be present for an infection to occur. The presence of pathogen doesn’t mean that an infection will occur. This happens as a result of a sequence of events that take place between the infectious agents, the host and the environment – in a process known as the ‘chain of infection’.

Infection: • An invasion of pathogens or microorganisms into the body that are capable of producing disease. The portal of entry is the ability of infectious agents to enter the reservoir.
