HIV/AIDS is only transmitted through the bodily fluid of one person that is put into the body of another person. this would be like a baby drinking the breast milk of a mother with HIV or having sexual intercourse with someone who is HIV positive blood. HIV cannot be spread through the mouth (unless the person has oral bleeding when performing oral sex) by kissing or sharing salvia. it is also not transferred through tears from the eyes, through the pores by sweat, and through the ears or nose (unless there are cuts in either the ear or nose and the blood, semen, breast milk, etc of an HIV positive person goes in that cut; this rarely happens). let me know if you have any further questions :)
There is more than two but it could go either way and the two skills wade would need is logic skills and communication those are the two biggest skills you need for radiology
