Define "infection control."

Infection control refers to the set of practices implemented to prevent the spread of infections, particularly in healthcare settings. This definition encompasses a range of actions such as proper hand hygiene, the use of personal protective equipment (PPE), sterilization of tools, and maintaining a clean environment to minimize the risk of transmitting pathogens. These practices are critical for safeguarding both healthcare professionals and patients, especially those who may have compromised immune systems or are undergoing procedures that increase their risk of infection.

The other choices do not align with the definition of infection control. Providing emergency care focuses on immediate medical intervention rather than preventing infections. Protocols for composting biohazard waste concern waste management and disposal rather than infection prevention in a healthcare context. Finally, guidelines for promoting physical exercise pertain to health and fitness, which is unrelated to infection management. Thus, the focus on practices to prevent infection spread is what makes the first choice the correct answer.
