World Impact
To understand the devastation of AIDS, you have to understand the high mortality rate of people who develop the disease. If you counted every person in the city of Chicago, which is about 3 million, you would get the idea of how many people died worldwide from AIDS in 2002. Basically, that means that each year AIDS kills the same number of people that populate the third largest city in the United States.

More than 42 million people are infected with the HIV virus worldwide, with as many as 28.2 million of those cases in sub-Saharan Africa. Additionally, another 5.3 million new HIV infections occurred in 2002, which represents almost 15,000 new cases per day. The regions with the greatest number of people living HIV/AIDS, according to the World Health Organization, include:

  • Sub-Saharan Africa - 29.4million
  • South and Southeast Asia - 6 million
  • Latin America - 1.5 million
  • North America - 980,000
  • Eastern Europe/Central Asia - 1.2 million

AIDS is clearly one of the worst health crises facing the world today. Without any truly effective treatment, most health experts are putting an emphasis on prevention to stop the spread of HIV. To learn more about HIV and AIDS, go to the next section.
