David Willman does another deft job with the story of BioWatch, hopefully in time to influence the upcoming purchase of BioWatch’s next generation of detectors. None have yet worked as billed.
The “detectors” are simply air samplers: filters attached to vacuum tubes. The filters have to be collected, then tested elsewhere using PCR devices specific to each microbial pathogen of concern. The PCR (polymerase chain reaction) devices theoretically ought to be specific enough to distinguish deadly germs from related, but benign relatives.
The fact that they don’t, suggests that the idea behind the system is flawed. Why waste billions on the next gen device, when the theoretical underpinning of BioWatch is a failure?
Colorado has experienced multiple false alarms. Willman interviewed Colorado’s former chief medical officer of the Department of Public Health:
“I can’t find anyone in my peer group who believes in BioWatch,” said
Dr. Ned Calonge, chief medical officer for the Colorado Department of
Public Health and Environment from 2002 to 2010. “The only times it goes off, it’s wrong. I just think it’s a colossal waste of money. It’s a stupid program.”
However, the BioWatch boondoggle does allow our leaders to claim they
are protecting us: and that may be enough to continue the program.
