AIDS risk estimate may help you answer family planning questions.

A newly developed risk assessment instrument can help family planning clinicians to answer their clients' questions about whether they are likely to develop acquired immunodeficiency syndrome (AIDS). The client's sexual history is used as the basis for estimating the degree of risk. The risk of human immunodeficiency virus (HIV) infection is, according to this instrument, 1 in 50'000,000 if a condom was used and 1 in 5,000,000 if a condom was not used following 1 sexual encounter with a partner whose HIV serostatus is unknown but who is hot in a group at high risk of AIDS. The HIV risk is 1 in 110,000 if a condom was uses and 1 in 16,000 if a condom was not used following 500 sexual encounters with a partner whose serostatus is unknown but who is not in a high-risk group. On the other hand, the risk of HIV infection is 1 in 10,000-100,000 if a condom was used and 1 in 1000-10,000 if a condom was not used after 1 sexual encounter with a partner whose HIV status is unknown and who is in a high-risk group. This risk increases to 1 in 21-210 if a condom was used and to 1 i3-23 if a condom was not used following 500 sexual encounters with a partner whose HIV status is unknown and who is in a high-risk group. Finally, the risk of HIV infection following 1 sexual encounter with a partner who is HIV seropositive is 1 in 110,000 if a condom was used and 1 in 500 if a condom was not used. Despite the protective effects of condoms against AIDS, the best preventive measure is selection of low-risk partners.
