Prevalence of human immunodeficiency virus infection in a sample of immigrants in the United States.

EDITOR'S NOTE: Years ago, experts predicted that the acquired immunodeficiency syndrome would spread to every part of the world and every part of society. The articles by Studemeister and Kent and Calonge and co-workers(*) that follow are further evidence that this is happening. These and other articles we will publish in the next few months confirm our worst fears and challenge all of us to continue engaging in basic, applied, and behavioral research and to continue providing the very best care, ranging from prevention through hospice, with an emphasis on compassion.
