HIV infection is usually acquired through sexual intercourse, exposure to infected blood, or perinatal transmission. The mode of acquiring HIV infection was undetermined in 4 percent of the cases originally reported to the Centers for Disease Control and Prevention (CDC). A careful review of 32,497 cases, however, revealed that only 0.2 percent had no clearly defined risk factor. The distribution of the modes of transmission of HIV infection varies in different countries. In resource-limited areas, vaginal sex is responsible for 70 to 80 percent of HIV infections, and perinatal transmission and injection drug use (IDU) for 5 to 10 percent each. In contrast, during the first 25 years of the epidemic in the US, male-to-male sexual contact and IDU accounted for about one-half of cases

5 out of 10000 is your risk as you mentioned according to CDC.
