Justine has been diagnosed with AIDS. What does this MOST likely mean for Justine?

Question

She received a vaccine for AIDS that was ineffective.


She previously had human immunodeficiency virus (HIV).


Her parents passed on genes to Justine that cause AIDS.


Her symptoms include paresthesia, meningitis, and paralysis.

Answer 1

The statement that is MOST likely true for Justine, given her diagnosis of AIDS, is:

She previously had human immunodeficiency virus (HIV).

AIDS (Acquired Immunodeficiency Syndrome) is the advanced stage of infection caused by the human immunodeficiency virus (HIV). Therefore, a diagnosis of AIDS indicates that Justine was previously infected with HIV, which has progressed to the point of severely affecting her immune system.
