The entire blood donation routine lifestyle/behaviors questionnaire of self-reporting is of little value because people can make mistakes or intentionally misrepresent their status. A far better approach is to test all donated blood, all the time for significant communicable, incurable diseases. If it's "too expensive," then newer/cheaper tests need to be developed. |

The reason for the questionnaires is that a recent HIV infection won't always show up even with the best most sophisticated tests.
So we do the best we can to screen out people who are most likely to have recently acquired HIV. Screening out IV drug users, men who have sex with men, sex workers, and people form countries with high rates of HIV, eliminates the vast majority of new HIV cases without eliminating a large percent of the population.
Again, people can lie so self-reporting may not be worth it. You'd have to do a study to find out. And even if it is, the number of HIV infections prevented may be so low that it doesn't justify infringing on the rights of people to donate. But, that's the debate.
