Immunodeficiency disorders involve malfunction of a person’s immune system. These disorders can result in infections that develop and recur more frequently, are more severe, and last longer than usual. Which of the following is NOT one of the main ways in which immunodeficiency disorders develop?
A) From having a chronic and/or serious disorder, such as diabetes or cancer B) From using certain drugs C) From being present at birth and usually inherited D) From close contact with a person who has an immunodeficiency disorder
The correct answer is D) From close contact with a person who has an immunodeficiency disorder.
Explanation: Immunodeficiency disorders can occur due to various factors—chronic illnesses, certain medications, or genetic factors. However, being in close contact with someone who has an immunodeficiency does not cause a healthy person to develop an immunodeficiency disorder; these conditions are not contagious and cannot be transmitted through contact.
