- All six links: pathogen, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host (Correct answer)
Correct answer: All six links: pathogen, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host
Disease transmission requires all six links of the chain of infection to be intact; breaking any single link prevents infection from spreading.
Question 7: When a healthcare professional identifies a potential safety concern but fears retaliation for reporting it, this barrier is known as:
