摘要

BEST ESTIMATES PLACE THE NUMBER OF INDI-viduals 13 to 24 years of age who are newly diagnosed with human immunodeficiency virus (HIV) infection each year at more than 10 000.l This represents approximately 20% of all newly diagnosed cases of HIV annually. While this number is large, the most troubling statistic concerning HIV infection among youth is that more than 48% of those youth who are infected are unaware of their status as opposed to 25% of infected individuals in all other age groups.
