How is "infection" defined in the context of infection control?

Infection is defined as the invasion and multiplication of microorganisms in body tissues. This definition emphasizes the critical process where pathogens, such as bacteria, viruses, or fungi, enter the body, begin to reproduce, and can lead to disease. Understanding this definition is vital for infection control because it underscores the importance of preventing microorganisms from entering and proliferating within the body.

Recognizing infection in this way helps health professionals focus on practices that minimize risks, such as proper sterilization techniques, the use of personal protective equipment, and adhering to hygiene protocols. This context reinforces the need for rigorous infection control measures, as the goal is to prevent these microorganisms from establishing themselves and causing harm.
