    Answer is B. Among U.S. cases of AIDS, male-to-male sexual contact represents the most frequently reported mode of HIV transmission among persons with AIDS. However, over the past few years, the number of newly reported cases of AIDS among other groups, including IV drug users and heterosexuals, from certain large cities have surpassed the number of newly reported cases among men who had sex with men. The proportion of new cases attributed to IV drug use and heterosexual sex has increased dramatically over the past ten years. There is a small but existent occupational risk of HIV transmission. Large, multi-institutional studies have indicated the risk of a penetrating injury, such as a needlestick from an HIV-infected person, to be approximately 0.3 percent. Risk posed by a mucocutaneous exposure is probably closer to 0.1 percent. Current measures used to screen donors now include p24 antigen testing which has resulted in a further decrease in the risk of being infected from a unit of blood to at most 1 in 450,000 to 1 in 660,000. Pediatric AIDS arises mainly from infants born to mothers who are HIV-infected. The remainder are generally exposed via blood transfusions. Although HIV can be rarely isolated from saliva, there is no convincing evidence that saliva can transmit HIV infection, either through kissing or other exposures, such as occupationally to health care workers.
