A LOOK AT THE LATEST AIDS PROJECTIONS FOR THE UNITED-STATES

As of the end of April 1990, 132,510 cases of acquired immunodeficiency syndrome (AIDS) had been diagnosed in the United States and reported to the U.S. Centers for Disease Control (CDC). In the first four months of 1990, 14,729 cases were reported to CDC, whose task it is to monitor the epidemic of human immunodeficiency virus (HIV) infection. Recent reports in the press and in the scientific literature have noted a slowing of HIV infection rates among some groups of homosexual men and intravenous drug users. A recent Public Health Service report stated, ''It is now clear that the Nation is not dealing with a single epidemic of HIV infection with uniform characteristics.... The populations most affected and the resources available to treat and combat the spread of HIV may differ markedly from one geographic area to another.''
