| Extremely Drug Resistant Tuberculosis XDR-TB - VOA Story |
 |
U.S. health officials have quarantined an airline
passenger who may have exposed others to a
potentially dangerous form of tuberculosis. The
unusual decision was made after the passenger took
flights from the U.S. to Europe, then to Montreal,
Canada before reentering the United States. The
man has what's called 'Extremely Drug Resistant'
tuberculosis. Passengers and crew from both
flights have been urged to be tested for the
infection. XDR-tb is an especially virulent form
of the disease that is resistant to standard drug
treatment.
The World Health Organization says about nine
million people around the world have TB and 1.6
million die from it every year. The greatest
burden is in South and East Asia, followed closely
by Africa and the Western Pacific regions, all
adding up to 85 percent of the world total.
But TB persists and mutates into drug-resistant
strains harder to cure because many patients fail
to finish taking their medicine. For years, the
World Health Organization has promoted directly
observed therapy by local health care workers who
go to patients' homes to make sure they take their
pills. But in poor countries with weak health
systems, health workers to do this are in short
supply.
As a result, bacterial resistance to at least two
common TB drugs is spreading, requiring newer,
more expensive, and more toxic compounds to do the
job.
"One of the biggest challenges is we know it's out
there, but we don't know how much of it is out
there," says Joann Carter. She is with the
non-governmental group RESULTS, which helps fund
medical projects in developing countries. She
notes that an even more dangerous TB strain has
developed recently. The bacterium has mutated
further into a form resistant to most of the older
and newer drugs. This so-called extremely drug
resistant strain, or XDR tuberculosis, was first
noticed in South Africa, fueled by the HIV
epidemic that weakens patients' ability to fight
such diseases.

Very rough mix of a track from my forthcoming
album. I got a new synth yesterday (an MFB
SynthII, if you are interested) and thought I'd
try it out instead of my tb-303 on this track, to
see if it had acid potential. It is being
sequenced by my korg emx, which is also providing
the drums and the synth parts.
The finished track will sound much better as I
rushed this mix and some parts are a bit loud. If
you like it check out my other tracks and look out
for some more coming soon.
