How many cases of AIDS are there in the United States?

The latest data I can find is from the end of 2003, so the numbers will be slightly higher today. The prevalence of HIV positive individuals is estimated to be between 900,000 and 1 million people in the United States (many do not know they have the disease, so that's why there is only an estimate). The prevalence of patients with AIDs in the United States is just over 400,000. There are about 45,000 new cases of AIDS each year.
