Human Civilization is Losing the War Against Superbugs
by David Gutierrez, staff writer
(NaturalNews) The steady medical advance against viruses and bacteria
that many experts were trumpeting in the early days of vaccines and
antibiotics seems to have stalled, if not reversed. The ongoing
emergence of new and increasingly drug-resistant diseases is now
causing many to question whether the war against microbes is one that
can ever be won.
"It is a war of attrition," said David Livermore of the United
Kingdom's Health Protection Agency. "There have been points where we
have been advancing, and points when we have had to beat a retreat. If
we were having this conversation 20 years ago, for instance, we would
be celebrating the vaccine for bacterial meningitis."
The news these days contains less of celebration and more of alarm.
Even with H1N1 swine flu now appearing less dangerous than originally
thought and infection rates of the superbug Methicillin-resistant
Staphylococcus aureus (MRSA) falling in the United Kingdom, widespread
antibiotic use and a globalized world have made the processes of
pathogen evolution and spread faster than ever before.
The threat from the highly lethal H5N1 bird flu - a mere mutation away
from a highly contagious form - has not abated, and other infectious
threats thought long vanquished continue to rear their heads. China,
for example, is currently battling an outbreak of pneumonic plague
caused by Yersina pestis, the same bacterium that wiped out a third of
Europe's population as the Black Plague. Meanwhile, longer lifespans
have encouraged the emergence of suberbugs such as Clostridium
difficile, which preferentially targets elderly patients who have
already been treated with antibiotics.
"Sensible prescribing is part of the answer, but we also need new
antibiotics," Livermore said. "It's not one of the most attractive
areas for pharmaceutical companies as people don't take them for very
long, unlike treatments for heart disease or cancer."
"We will always be at war with microbes," said Primrose Freestone of
the University of Leicester. "Their genetic promiscuity is impressive."
