Tracking the AIDS Epidemic in the
US
An example of spatial diffusion
30 to 40 million people have died
from AIDS worldwide, including 2
million in 2007.
33 million worldwide are currently
infected with HIV/AIDS, of whom 2
million are children.
1% of all adults aged 15 to 49 in
the world are living with HIV,
including .6% of Americans.
2.7 million people contract HIV
each year, or about 7,400 each day.
Half of all people infected with HIV
are women.
HIV’s origins can be traced to Africa;
the first infection was a man in
Kinshasa, Congo, in 1959.
HIV is devastating sub-Saharan Africa,
where it is primarily spread among
heterosexuals. In Botswana, 39% of
the adult population is infected with
HIV.
In Zimbabwe, a country of 13
million, more than 780,000
children have been orphaned by
the AIDS epidemic.
In sub-Saharan Africa, 76% of the
young people with HIV are female.
They are four times more apt to
contract AIDS through heterosexual
sex, they progress to full-blown AIDS
faster, and they die sooner.
In the US, it is believed that the
first case entered via Haiti. It
spread primarily among
homosexual males and intravenous
drug users.
