HIV/AIDS is a global pandemic. As of 2010 approximately
34 million people have HIV worldwide. Of these approximately
16.8 million are women and 3.4 million are less than 15 years
old. It resulted in about 1.8 million death in
2010, down from 3.1 million in 2001.
Sub-Saharan Africa is the region most affected. In 2010, an estimated 68%
(22.9 million) of all HIV cases and 66% of all deaths (1.2 million)
occurred in this region. This means that about 5%
of the adult population is infected and it is believed to be the cause of 10% of all deaths in
children. Here in contrast to
other regions women compose nearly 60% of cases. South Africa has the largest population of people with HIV of
any country in the world at 5.9 million. Life expectancy has fallen in the worst-affected countries due
to HIV/AIDS; for example, in 2006 it was estimated that it had dropped from 65
to 35 years in Botswana.[
South & South East Asia is the second most affected; in 2010 this region contained an
estimated 4 million cases or 12% of all people living with HIV resulting
in approximately 250,000 deaths. Approximately 2.4 million of these cases
are in India. Prevalence is lowest in
Western and Central Europe at 0.2% and East Asia at 0.1%.
In 2008 in the United States approximately 1.2 million people
were living with HIV, resulting in about 17,500 deaths. The Centre for Disease
Control and Prevention estimated that in 2008 20% of infected Americans were
unaware of their infection. In the United Kingdom as
of 2009 there where approximately 86,500 cases which resulted in 516 deaths. In Canada as of 2008 there were about 65,000
cases which results in 53 deaths. Between the first recognition of AIDS in 1981
and 2009 it has led to nearly 30 million deaths.
