A Global Pandemic?
What is HIV?
HIV (human immunodeficiency virus) is the virus that causes AIDS (acquired
immunodeficiency syndrome). This virus is passed from one person to
another through blood and sexual contact. In addition, infected pregnant
women can pass HIV to their baby during pregnancy or delivery, as well
as through breast-feeding. Nobody is sure where HIV came from. Scientists
have different theories about the origin of HIV, but none have been
proven. The earliest known case of HIV was from a blood sample collected
in 1959 from a man in Kinshasa, Democratic Republic of Congo, but how
he became infected is unknown.
HIV to AIDS
Being HIV-positive, or having HIV disease, is not the same as having
AIDS. Many people are HIV-positive but don't get sick for many years.
As HIV disease continues, it slowly wears down the immune system – that
is the system within the body which fights infection and disease. HIV
disease becomes AIDS when your immune system is seriously damaged.
As this happens, viruses, infections and bacteria which normally the
body can fight off become more dangerous – these infections are
called ‘opportunistic infections’. Without treatment, these
opportunistic infections can kill you.
Worrying statistics
Over 40 million people world wide now living with HIV, of whom about
95% are in developing countries. It is estimated that about 14,000
people become newly infected with HIV every day. More than half of
these newly infected with HIV today are between the age of 15 and 24
years old, whilst there are an estimated 3 million children already
living with HIV/AIDS. Of all new infections in 2001, 68% were in Sub
Saharan Africa and 16% in South and South East Asia. To date, over
14 million children have been orphaned by HIV/AIDS.
Vested interests?
There is no cure for AIDS or HIV. There are only drugs that can slow
down the HIV virus, and slow down the damage to the body’s immune
system. These patented drugs are currently very expensive, and the
fact that treatments work better when a combination of drugs are used
together makes treatment exorbitant for many in developing countries.
Despite attempts by the World Trade Organisation (WTO) to make cheaper
generic drugs available, no agreement was reached in December 2002 – as
the USA refused to sign up to the proposals agreed by 143 other countries.
