Question

select the correct answer
felicia developed an infection after stepping on a sharp object. in this scenario, the skin puncture caused by the sharp object was what link in the chain
of transmission?
a. susceptible host
b. infectious agent
c. portal of entry
d. reservoir
e. portal of exit

Explanation:

The chain of transmission has several links. The portal of entry is the way a pathogen enters a new host. Here, the skin puncture (caused by the sharp object) is the route through which pathogens could enter Felicia's body. A susceptible host (A) is the person at risk of infection (Felicia herself). An infectious agent (B) is the micro - organism causing the infection. A reservoir (D) is the source of the pathogen. The portal of exit (E) is how the pathogen leaves the original host (not relevant here as the focus is on entry into Felicia).

Answer:

C. portal of entry
