Avoiding the swine flu

bidengaff

Since I’ve been asked about my take on the swine flu situation a few times in the comments section and numerous times by other people I know, I figured I would post on the subject.  Re the above cartoon: I agree with the President.

I don’t think the situation is nearly as bad as many people – including our esteemed Vice President – seem to think it is.  Whenever I hear reports of panic like those we’ve been bombarded with over the past week, I always think of what H.L. Mencken had to say in such circumstances:

The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.

Bye bye Guinea worm

When I took my parasitology course in medical school I was exposed for the first time to all the loathsome diseases that are unheard of here but are a part of daily life in other parts of the world. Here people go nuts and rush to the emergency room if they find pin worms in their kid’s stool; there having a Loa loa worm creep across your eye is a common occurrence and only a minor bother.

I was fascinated with my study of liver flukes, roundworms, tapeworms and all the other parasites afflicting primarily those in tropical areas. The most vile yet amazing of these creatures was to me Dracunculus medinensis, the Guinea worm. This parasite causes untold misery to those it afflicts, and is now, as this BBC piece relates, on its way to extinction. For people living in areas the Guinea worm infests, I’m sure this is wonderful news.

What the BBC neglected to mention is that the eradication of the Guinea worm has been effected in large measure by none other than our former president, Jimmy Carter. Carter, in my opinion, wasn’t much of a president, but he has been a terrific ex-president when he avoids politics and sticks to humanitarian issues. This Carter Center he and his wife founded has been instrumental in educating people in areas where the Guinea worm is common to take the needed steps to intervene in the parasite’s life cycle and disrupt its ability to reproduce. The BBC reports: Read more »

A cautionary tale of mucus fore and aft

Let’s engage in a sort of thought experiment. Let’s assume that way back in the early days of medicine doctors always wanted to see us cough up mucus from our lungs. Since mucus is a kind of breeding ground for all kinds of nasty bacteria, it would make sense in the olden, pre-antibiotic days to want patients to hack up as much of this stuff as possible to get it out of the body where the bacteria could no longer wreak their havoc.

Let’s assume that doctors of old–who didn’t realize that the excess mucus was the body’s way of ridding itself of something foreign, i.e., the bacteria or viruses causing the infection–started equating coughing up ‘healthy’ amounts of mucus with good health. It’s not too far a leap to imagine these doctors supposing that if they could get their patients to cough up stuff all the time, the respiratory system would stay clear of the mucus that harbors all the pathogens that cause lung problems. Druggists might come up with concoctions that would cause people to cough, even if they didn’t need to.

Now let’s imagine that the idea that coughing up large amounts of mucus-laden sputum reaches the point of a national obsession. People, especially the elderly for whom respiratory infections are much more dangerous, discuss with one another how much sputum they produce and how often. If they don’t cough as much or as productively as they perceive those around them are doing, they go to their doctors who prescribe a sputum inducing medicine for them. People everywhere are obsessed with keeping their respiratory systems clean.
