Multiple Choice
Manny has contracted a virus that is destroying his body's immune system. Manny most likely has:
A
Hepatitis B virus infection
B
Prion disease
C
Viroid infection
D
Human Immunodeficiency Virus (HIV) infection
Verified step by step guidance1
Step 1: Understand the problem context. The question describes a virus that destroys the body's immune system, which is a key clue to identifying the correct infection.
Step 2: Review the options given: Hepatitis B virus infection, Prion disease, Viroid infection, and the correct answer, Human Immunodeficiency Virus (HIV) infection.
Step 3: Recall that Hepatitis B virus primarily affects the liver, not the immune system directly; Prion diseases are caused by misfolded proteins and affect the nervous system; Viroids are infectious RNA molecules that affect plants, not humans.
Step 4: Recognize that HIV specifically targets and destroys CD4+ T cells, which are crucial components of the immune system, leading to immune system failure.
Step 5: Conclude that the virus destroying the immune system in this context is HIV, which causes Acquired Immunodeficiency Syndrome (AIDS).
