Answer 1

1. Cleaning refers to the removal of visible dirt, debris, and organic matter from surfaces. It does not necessarily kill pathogens. Sanitization is the process of reducing the number of pathogens on a surface to a safe level, typically using chemicals. Disinfection is the process of killing or inactivating pathogens on surfaces, but it may not remove all microorganisms, especially resistant bacterial spores. Sterilization is the process of killing or removing all forms of microbial life, including bacteria, viruses, fungi, and spores.2. The new term that replaces nosocomial infections is "healthcare-associated infections" (HAI).3. The "chain of infection" is a cycle or pathway of infection that begins with the creation or source of infection and ends with pathogen entry into the body.
