Final answer:
The cycle of infection can be broken by using appropriate doses of antimicrobial drugs, preventing pathogen transmission, reducing infection sources, and boosting host resistance. Responsible antimicrobial use is crucial to prevent drug resistance.
Step-by-step explanation:
The cycle of infection can be broken by implementing several strategies. These include using large doses of antimicrobial drugs when necessary and appropriate to ensure complete eradication of the infectious agents, blocking transmission of pathogens by employing hygiene practices and infection control measures, reducing the reservoir of microorganisms by eliminating sources of infection, and increasing host resistance through vaccination and supporting the immune system. However, it is important to use antimicrobial drugs judiciously to avoid the development of drug resistance, and treatment must be completed as prescribed to prevent recurrence of infection. Health professionals play a crucial role in encouraging the responsible use of antimicrobials and educating patients about the importance of completing their course of treatment.
