Question

Felicia poked herself while disposing of a needle that she had just used to administer medication to a patient. She was later tested for infection from this needle stick and tested positive for human immunodeficiency virus (HIV). In this scenario, the needle stick was what link in the chain of transmission?

Answer 1

The needle stick was the reservoir to the portal of exit of the chain of transmission

Answer 2

Portal of entry

Step-by-step explanation:

Portal of entry is the pathway by which the infectious agent reaches the susceptible host. Or that is the way that led a person to be infected by the microorganism that causes an infection. In the case of the above question, Felicia poked herself as she discarded a needle she had just used to administer medication to a patient. This patient was infected with the HIV virus, the needle used in the patient came into contact with the blood and eventually became a vehicle for transmission of the virus. When Felica poked herself with this needle, she contracted the virus. In this case, the needle was the pathway through which the virus hit Felicia. The needle is a portal of entry.
