Control of infection involves breaking the chain of infection. What 3 links in the infection chain must be present in order for an infection to occur?
- A.
Infectious agent, moist conditions, means of transmission
- B.
Dirty conditions, susceptible host, prolonged exposure
- C.
An infectious person, intimate contact, prolonged exposure
- D.
Infectious agent, means of transmission, susceptible host
Correct Answer
D. Infectious agent, means of transmission, susceptible hostExplanation
In order for an infection to occur, three links in the infection chain must be present. The first link is the infectious agent, which is the pathogen or microorganism that causes the infection. The second link is the means of transmission, which is how the infectious agent is spread from one person to another, such as through direct contact or through contaminated objects. The third link is the susceptible host, which is a person who is not immune to the infectious agent and can become infected. Therefore, all three links - infectious agent, means of transmission, and susceptible host - must be present for an infection to occur.Rate this question:
