AIDS and reproductive health.
Over 24 million adults worldwide have been infected with HIV. Primarily a sexually transmitted disease, AIDS is inexorably linked to reproductive health and care. Because HIV tends to infect those who are in their reproductive years, the impact of this disease on population growth and life expectancy is projected to be immense in some parts of the world, especially in sub-Saharan Africa. Not least is the challenge to individual families and infant care programs to care for AIDS babies. Estimates of the rate of vertical transmission of HIV range from < 10 to 46%. Transmission through sexual contact accounts for 75-85% of HIV infection worldwide, and today, nearly 20 years into the epidemic, the main tool to stall the spread is advocating change in sexual conduct. Numerous studies leave no doubt that the attributable risk of co-infection with other STDs--both ulcerative and non-ulcerative--in heterosexual transmission is substantial. The only known contraceptive method proven to reduce both infectiousness and susceptibility to HIV is barrier contraception. Spermicidal agents currently available have not been shown to reduce HIV concentrations in genital secretions, or to reduce transmission of the virus. The challenges that lie ahead are tremendous: we must continue to focus on development of affordable preventive measures; urge policy-makers to back further research in prevention to complement condom use; and advocate for continued support of basic research to learn more about fundamental mechanisms of HIV transmission.
