DISTRIBUTION OF HIV TYPE-1 INFECTION IN CHILDBEARING WOMEN IN CALIFORNIA

The incidence of acquired immunodeficiency syndrome (AIDS) is increasing among California heterosexuals and children. To assess human immunodeficiency virus (HIV)-1 infection in childbearing women, we conducted a blinded serosurvey of newborns. Dried blood specimens taken from 99% of California births during the third quarter of 1988 (n = 135 808) and linked only to maternal demographic categories were tested for HIV-1 antibody by enzyme immunoassay and confirmed by Western blot. Period prevalence of HIV-1 infection was 7.4 per 10 000 childbearing women. Prevalence was highest for Black women and was also elevated for Hispanic and San Francisco Bay Area women. Findings suggest that California Hispanic women will make up an increasing proportion of new AIDS cases.
