what is a source of infection
Answers
Explanation:
Source of infection:
An object is designed as the source of infection, is one in which the agent of infection lives and propagates. Can be man or animal from which the infectious agent is secreted into the outer environment and from there to individuals. In certain circumstances, the outer milieu can be the source of infection where the agent lives as a saprophyte ( lives on dead matter) e.g. mycoses and legionella.
Man as a source: A person can be the source of infection in the following cases:
1) During the incubation period of a disease- in some infections the agent is secreted during the incubation period this is important as the infection is usually not known (e.g. Hep A and B)
2) Sick man- in clinical, abortive ( short and mild without usual pronounced clinical symptoms) , atypical or apparent forms.
3) Convalescent – secretion of agents occurs during convalescence (gradual recovery of health and strength after illness) ie. as in pertussis
4) Carriers- short term ( salmonalla), long term ( typhoid fever) or intermittent (secretions at certain certain periods)
