What is the percentage of persons in the USA that have HIV/AIDS? And what rank is the United States on a global scale?
This was a test question I included last week on a test to second year medical students (if you are one of my students, No Cheating!).
There are about 40 million people with HIV worldwide and about 1 million in the US. As a nation, the US ranked 65 out of 168 nations ranked in the 2003 CIA World Factbook. http://www.capitals.com/rankorder/2155rank.html
