Sexually transmitted infections (STIs) mostly go unnoticed until it is too late and the consequences of sexually transmitted diseases (STDs) become incurable. Asking questions “Do you have AIDS, gonorrhoea, chlamydia, syphilis, herpes, trichomonas, candida, hepatitis B, hepatitis C, CMV infection, genital warts (including these types that  cause cervical cancer), and the like?” makes no sense since infected people simply have no idea what they carry and transmit to others. Only a doctor can diagnose an STI, because the signs and symptoms of STDs [1] vary and overlap  with symptoms of other STDs and all other diseases. It may create a sense of false security asking “Have you been tested for HIV/AIDS?” since an infected person can transmit HIV during the window period, which is the time from getting infected until a blood test can detect any change [2]. Much more effective would be avoiding risks of deadly diseases by following, if possible, the strict rules of The UK National Blood Service which say plainly who can't give blood [3]. Those who can’t give blood because they are or might be infected with HIV, hepatitis B, C and/or syphilis etc. can’t be regarded as safe and might be   held liable for passing an STI to a virgin unaware of risky behaviours of his or her partner.
