Tracing salmonella

How do public health officials seem to know exactly how many cases of salmonella are out there? Today the Washington Post claims a strangely precise 1,017. What are the symptoms? How is it diagnosed? Is it always serious enough to require medical care? I am thinking that there are lots more people who might have it without symptoms serious enough to see a doctor about, but that finding those people would provide a huge amount of information about the source.

My bottom-line question is that I am wondering why we don’t see articles that say, “If you have the following symptoms, even if you don’t feel sick enough to see a doctor, please report them to your local health authorities or your doctor to help us track the salmonella outbreak.”

Simple answer: they do not. The numbers you see reported are confirmed cases. The majority of bacterial enteritis cases resolve without medical intervention.

There are many differant strains, or varieties of Salmonella, so its possible to pin the culprit down, but it isn’t easy.

Some of the differances between strains are incredibly subtle, and it takes bacterio-phaging techniques to differentiate.

To add to the above, salmonellosis is a reportable disease in many (if not all) states – that is, if it is definitively diagnosed in a person, the health professionals involved are obligated to report the case to the health department.

I have had salmonellosis (caught it from a horse that I was caring for, won’t bore you with the gross details), and it sucks the big one. Better than cancer, but that’s about all I can say for it, besides the weight loss effects.

Missed a couple questions in the OP:
It is diagnosed with a fecal culture and/or PCR.

It does not always require medical care, since antibiotics do not shorten the course of the disease very much and may prolong shedding. Anti-emetics and IV fluids may help keep you alive/less miserable while you wait for it to run its course.

My doctor decided to let me tough it out sans fluids or anti-emetics, but that is more a story for the Pit than GQ.

Sorry for the double post.

Yuuch. Equine Salmomellosis sucks big time. Profuse diarrhea shooting like a fire hose. I once saw a stable worker catch the spray into her face and she was hospitalized around 5 days later. :eek:

Thanks (NOT!), vetbridge, for supplying us with the gross details horsetech was kind enough to spare us from! :eek: :eek: :eek:

(The school I work for has an equine program and I can totally imagine that fire-hose spray happening.)

The Ohio State University by any chance? The University of Pennsylvania’s large animal facility has an isolation barn that deals primarily with Salmonella cases. Blecch.
