HIV, Emerging Disease
HIV is the classic emerging virus. As mankind's population grows, as
the environment degrades, as health systems break down, viruses
are presented with new evolutionary opportunities. A few decades
ago the ancestor of HIV took such an opportunity and established
itself in a human host. Aided by poverty, fast transportation
and a breakdown in social traditions, the virus quickly spread
worldwide and became a pandemic. AIDS was born.
The epidemic has come in waves. The first wave hit Africa - particularly
southern Africa - and remains the most advanced. As of 2003, the epidemic
in this region had already dramatically affected population structure and
longevity. Economic growth is slowing and the social fabric is beginning
to tear, as the burden of so many deaths erodes the structure of these societies.
This effect is particularly exaggerated by the fact that AIDS tends to
strike young adults in their economic prime.
There are tremendous web resources focused on AIDS. It is by far the
most visible of emerging diseases, largely since it has touched the
western world in addition to its impact elsewhere. However, given the social and
ecological factors driving AIDS, we can expect to see many more
emerging diseases of this type in the future.
It is probable that some of these coming plagues will be far worse than
the AIDS epidemic.
