A. Chain of infection
B. Disease transmission model
C. Infection prevention cycle
D. Pathogen life cycle

Answer 1

The subject of this question is the chain of infection and its components, which describes how pathogens are transmitted from one host to another.

Step-by-step explanation:

The subject of this question is the chain of infection, which describes the process of how pathogens are transmitted from one host to another. The six components of the chain of infection are:

1. Infectious agent - the pathogen that causes infection
2. Reservoir - the source or hiding place where the pathogen lives and multiplies
3. Portal of exit - the route by which the pathogen leaves the host
4. Means of transmission - the way the pathogen is spread from one host to another
5. Portal of entry - the route by which the pathogen enters a new host
6. Susceptible host - the next person or organism that can become infected

Understanding the chain of infection is important for identifying and interrupting the transmission of infectious diseases.
