Introduction

CDC (2009) estimates 1.2 million people in the United States (US) are living with HIV infection. • About 33 million people living with HIV worldwide

One in five (20%) of those people are unaware of their infection.

Despite increases in the total number of people in the US living with HIV infection in recent years, the annual number of new HIV infections has remained relatively stable. • New infections continue at far too high of a level, with

approximately 50,000 Americans becoming infected with HIV each year.
