List the six components of the chain of infection and describe how they contribute to the development of disease.
What will be an ideal response?
The six components of the disease process are the causative agent, reservoir, portal of exit from the reservoir, mode of transmission of the organism, portal of entry into the host, and susceptible host. The causative agent is the pathogen that causes the disease. The reservoir is where the causative agent lives, grows, reproduces, and thrives. The reservoir can be human, animal, environmental, or fomite. The portal of exit is the way in which the pathogens leave the reservoir. The portal of exit can be blood, body fluids, secretions, excretions, or wound drainage. The mode of transmission of the disease is the manner in which the disease is spread. This may be through direct contact, indirect contact, droplet spread, common vehicle, airborne, or vector borne. The portal of entry is the location where the microorganism enters the susceptible host. This can be through the skin, mucous membranes, respiratory tract, genitourinary tract, gastrointestinal tract, circulatory system, or the placenta. The susceptible host is the person who does not have enough resistance to the infectious agent and contracts the disease.
