The portal of entry is crucial in understanding infection transmission.
Portal of entry is the correct link in the chain of transmission in the scenario where Felicia developed an infection after stepping on a sharp object. The skin puncture caused by the sharp object provided a direct route for pathogens to enter her body and cause the infection.
