Prevalence of HIV antibodies in pregnant women with increased risk for AIDS.

The prevalence of Human immunodeficiency virus (HIV) antibodies in pregnant women varies widely between industrialized and developing countries. There is a lack of information about the status of HIV-infected pregnant women with increased risk for AIDS. Our objective was to determine the prevalence of HIV antibodies in pregnant women with increased risk at the Hospital of Obstetrics and Gynecology of the Mexican Institute of Social Security, Leon, Mexico, from December 18, 2003, through February 28, 2006.
