Did you ever wonder what the population of North and South America was before Columbus made his big “discovery”? As Charles C. Mann shows in his book “1491,” there is a wide diversion of opinions. The “Low Counters” estimate about 10 million while the “High Counters” guess it is more like 100 million. Why the high level of uncertainty? Seems native Americans – Aztecs, Mayans, Incas, Iroquois, Cherokees et alia – saw no need for taking censuses. Only when the Spanish arrived did the idea of taking body counts of the living become accepted.
And while the Spaniards certainly knew how to count, what they were counting were those who remained after smallpox, measles, influenza and other pandemics had decimated the various populations they were estimating. The idea that the western hemisphere was an empty continent waiting to be occupied by needy Europeans has been laid to rest along with the millions of native Americans who were killed off in short order by European diseases, particularly smallpox. In 1542 Bartolome de Las Casas, Spanish historian, Dominican friar, and American explorer, said that the Americas were so thick with people “that it looked as if God has placed all of or the greater part of the entire human race in these countries.” (Mann)
Zinnser, in his delightful book, “Rats, Lice and History,” comments on the relative unimportance of generals as compared with microbes. The outcome of more campaigns was determined by epidemic pathogens than by the brilliance of generals. How else could a piddly number of conquistadors and colonists have “opened” up the Americas for settlement and exploitation?
Although the science is disputed, it is not unreasonable to believe that the native Americans attempted to upstage the European invaders – both human and microbial – and their “Small Pox” by exporting back to Europe the “Great Pox.” (Syphilis, in case you didn’t know) Poetic justice? You decide.

Now there’s a title to arouse one’s curiosity.
The training of the immune system so that it can distinguish “self” from “non-self” is something we take for granted. Maybe we shouldn’t. It begins to appear that for many, if not all people, exposure to worms in early life is a significant part of that training. Without it we may end up with autoimmune diseases such as Crohn’s, asthma, autism, MS, etc.
Many patients with Crohn’s disease are now being treated successfully with worms such as the whipworm, Trichuris trichiura. It’s a long story but excitingly told by Rob Dunn in “The Wild Life of our Bodies” and by Moises Velasquez-Manoff in “An Epidemic of Absence.” Evolution has a curious bag of tricks and we would do well to pay attention to the entire ecosystem of which we are only one small part. That includes all the microbes we are so familiar with but also our helminth friends that we tend to think so revolting. Maybe our exquisite public health and sanitation systems have given us a back-handed slap by eliminating these “parasites.”
Have you taken a worm to lunch lately? (They don’t eat very much.)

In the book of Samuel in the Old Testament is the following text: “But the hand of the Lord was heavy upon them of Ashdod, and he destroyed them, and smote them with emerods, even Ashdod and the coasts thereof.” 1 Samuel 5:6 (KJV)
What are Biblical “emerods” (KJV)? “Hemorrhoids” as in some other translations? “Tumors” as in more recent translations? Or buboes?
Most people know about the Black Death, the plague that killed a third to a half of the population of Europe in a few years around 1350 AD. But how many know of the plague among the Philistines about 1320 BC? In 1 Samuel 5 & 6 there is a description of a plague of swellings in the groins of the victims (“they had emerods in their secret parts”). When the Philistines interpreted the plague as a result of their angering the God of the Israelites by their capturing of the Ark of the Covenant, the Philistines determined to send the Ark back with a guilt offering consisting of five gold “emerods” and five gold rats. Obviously they associated rats with the plague which certainly suggests that this was indeed bubonic plague.
Now if only they had known of the rat fleas, they might have sent an offering of five gold fleas instead of the rats and saved themselves considerable gold!
