HIV stands for human immunodeficiency virus, which can lead to AIDS (acquired immunodeficiency syndrome). This is a virus that, according to Centers for Disease Control and Prevention (CDC), that spreads through a person's body and attacks certain specific cells, called "CD4" of "T" cells. If the virus spreads sufficiently throughout the body then it becomes very difficult for the body to fight off infections -- and eventually, the deeper the virus penetrates the body the greater the chances of the person becoming infected with AIDS. This paper reviews the most recent medical care that can (in many cases) keep the virus from spreading; it also reviews the way in which a person can become infected with HIV and the stages that HIV goes through.

Where did HIV originate from?

Scientists believe that chimpanzees in West Africa may have had the HIV and when Africans hunted and killed the infected chimpanzees -- and ate them -- and the blood that humans came into contact with, because it was HIV positive, was the link to infect African humans. The belief is that this could have occurred as far back as the late 19th century. From Africa, according to the CDC, it spread to other parts of the world and apparently was present in the U.S. around the mid-to-late 1970s.

How many people in the U.S. are HIV-positive?

The CDC claims there are about 50,000 "new infections" each year in the U.S., and the CDC explains that the latest statistics show that 15,529 people diagnosed with AIDS died in the U.S. In 2010.

Is the number of new infections going down? No, in fact the nearly 30,000 of new HIV infections in 2010 was up by 12% from the new infections in 2008 (26,700) (CDC). Of the new HIV infections in 2010, 20% were with females -- and that represents a 21% increase for women since 2008. Eighty-four percent of the HIV infections for women came from "heterosexual contact" and 16% came from injecting drugs with infected needles.

African-Americans are only 12% of the U.S. population but in terms of new infections of HIV, blacks represented 44% of those new infections (CDC). Latinos represent about 16% of the U.S. population but they accounted for 21% of the new HIV infections in the year 2010, the CDC reports.
