The American Medical Association on Thursday approved a package of policies designed to help check the spread of AIDS, including a recommendation that states begin tracing the sex partners of people infected with the deadly virus.

The nation's largest doctors organization also renewed its call for mandatory testing of all prison inmates to see if they are infected with the human immunodeficiency virus that causes AIDS.

The AMA adopted a similar prison-testing proposal last year and reapproved it Thursday, despite objections from several doctors that it would accomplish little and cost too much.
