Germ Warriors edited by Clint Willis![](http://ir-na.amazon-adsystem.com/e/ir?t=abookfortoda-20&l=as2&o=1&a=1560255609)
is an anthology of stories about epidemiology and diagnosis. If it was a TV series, it might be named: CDC: The deadly cases.
For example, the chapter on food-borne pathogens explored the ubiquitous nature (30-50% incidence in some cases) of
e coli and
salmonella with emphasis on the dual challenges of today's large-scale and international food market.
First, with food items, both fresh and packaged, being sourced internationally, it is impossible for the USDA to monitor quality. However, this is a bit of a red herring, as the USDA doesn't even have resources to monitor domestic food production.
The second point is that the scale of operations magnifies problems and makes tracking difficult.
A single patty may mingle meat of a hundred different animals from four different countries. ... a single contaminated carcass ... can pollute eight tons of finished ground beef.
The chapter on the challenge of diagnosing rare diseases was one of the best. The example was a case of necrotizing fasciitis that "kills up to 70 percent of the people that get it."
This chapter introduces the Zebra problem:
an old saying taught in medical school: if you hear hoofbeats in Texas, think horses not zebras [Actually the phrase was coined by Dr. Theodore Woodward, professor at the University of Maryland School of Medicine, with no reference to Texas.]
For every case of necrotizing fasciitis, there are 3,000 cases of cellulitis with very similar symptoms.
In addition to necrotizing fasciitis,
e coli and
salmonella, the book covers ebola, plague, malaria, AIDS, Lassa virus, and mad cow disease. The anthology contains a diverse collection of (sometimes scary) stories of brave and dedicated medical scientists working to identify, prevent, and treat a wide collection of (fortunately) rare diseases.
Don't read it if you have unidentified symptoms or tendencies towards hypochondria.
