Examiners report
G2 feedback commented that the wording of this question should have been about the consequences of the presence of HIV. The question was designed to be about AIDS rather than the state of being HIV positive. It was in fact a poor discriminator, with most students giving the right response, which was C. Very few candidates were distracted by the other alternatives.
