The "chain of infection," i.e., the transmission of infectious agents in healthcare settings requires a

Explanation:

Chain of infection is the term that represents a set of related elements (source of infection, route of elimination, route of transmission, gateway) that demonstrates the process of spreading microorganisms that can cause disease in humans and other animals. . The existence of a chain of infection in healthcare settings requires the existence of a source or reservoir of infectious agents, the existence of a susceptible host with an infectious agent receptive entry portal, and the existence of a mode of transmission to the infectious agent.

A is the nurse, B is the bacteria, C is the mouth, and D is the mouth.

Explanation:

A is the nurse, B is the bacteria, C is the mouth, and D is the mouth.

Explanation:

The study of a living being is called chemistry.

The correct answer is C.

The infection caused by Felicia is due to the cut and this infection is due to cut by a sharp object.

In this case, the infection is due to the cut and caused by the iron molecule so the infection is not due to the pathogen.

In this case, the infection is due to the portal of energy in which the other pathogen is got enter in the wound and causes infection.

Hence, the correct answer is C that is portal of entry.
