Why is it that dogs can drink out of mud puddles with impunity but tots cannot? Or maybe we could but just don’t know it. I’m not about to suggest that we perform that experiment, but it does intrigue me that within the past several years there has been a lot of talk about the “hygiene hypothesis.” Since it doesn’t promote the wisdom of “hygiene,” maybe it should be called “antihygiene” or “lowgiene.” We have all observed with fear our little rug-rats wrapping their gums around all kinds of debris they have picked up off the non-hygienically approved floor. Do they survive in spite of—or because of—this activity?
The hygiene hypothesis claims that we are getting all kinds of diseases, such as asthma and Type I diabetes, because we are not training our immune systems adequately. How? By avoiding exposure to all the germs that used to visit us in early childhood before we began bathing in soap and alcohol twenty times a day.
World population was 2 billion when I was born and is now 7 billion. Would the 1918 flu pandemic have gotten off the ground in the absence of crowded military camps containing thousands of potential hosts waiting for the virus to arrive? Probably not.
Pandemics seem to be one of Mother Nature’s favorite strategies for population control. Earth could support several times its current people load if we went to a vegan diet, but does a world population of 20 billion humans sound like fun?
On our present course it seems certain that global warming will produce widespread effects that will not, in general, be desirable. But are we also setting ourselves up for a global pandemic that will prune the population to where it might have been in the first place if we had listened to those who have been warning us for some decades? Or will medical science give us enough vaccines and new antibiotics to shield us from whatever bugs come along?
Given our penchant for not doing anything until it is too late, I suspect that our experiment will continue but with Mother Nature at the controls—population controls. Keep your fingers crossed and your seat belt fastened. It may be a bumpy ride.

If you are a WWII history buff, you probably recognize the name of Josef Mengele, the ethically challenged Nazi physician who was known as “The Angel of Death.” Dr Shiro Ishii was his Japanese analog.
Dr Ishii, who later became a Lt General, was in charge of Unit 731 of the Imperial Japanese Army located in a suburb of Harbin, Manchuria. This was the most famous biological warfare death camp but not the only one. Others included even Nanking. Human subjects were inoculated and thousands died. The list of organisms included such delights as anthrax, meningococcus, influenza, smallpox, tetanus, typhoid, typhus, tuberculosis, plague and many others.
For effective Biological Warfare one has to know how to weaponize and disseminate the organisms. Aerosols? Bombs? Water supply? It was a difficult challenge. The heat of exploding bombs would kill organisms and those that survived that challenge would die off in the atmosphere from drying and UV exposure. This was also true of aerosols. Would there be person-to-person spread and could an epidemic be controlled? Many questions.
After the war, Ishii was captured. But instead of being executed for killing thousands of Chinese citizens and POWs, he was offered amnesty in return for turning over the records of his experiments to the Americans. Although medical ethics did not allow American researchers to perform experiments on living human beings, ethics did allow American authorities to exonerate the person who did the experiments.
General Ishii thus lived until October 9, 1959 dying at the age of 67. (“The Angel of Death” lived until February 7, 1979 also dying at the age of 67 in Sao Paulo, Brazil although assiduously hunted by the Israeli Mossad.)
Makes me wonder, what is ethics anyway?

“Kate Moran was an only child” may not compete with “Call me Ishmael” or “It was the best of times, it was the worst of times” as an opening salvo, but it will do. In this novel, Richard Preston wanders from the arena of fact into fantasy. But when one deals with viral hemorrhagic fevers, the distance is very small. The “Cobra” virus in the story is a genetically engineered combination of a rhinovirus and smallpox that attacks the brain and liquefies it and is meant to be an agent of bioterrorism..
It’s reported that President Bill Clinton read the book and was so unnerved by it that he called his science advisers together for advice. That led to Donald Ainslie Henderson forming the Johns Hopkins University Center for Civilian Biodefense Studies. D.A., as he was always known, was the person mainly responsible for organizing the highly successful campaign to eradicate smallpox and was also one of my mentors in the Epidemic Intelligence Service course I took at CDC in 1957. At that time he was one of Alexander Langmuir’s bright young acolytes. Since the conclusion of the smallpox crusade around 1980, he has been a leading light in promoting bioterrorism defense.
Richard Preston, who is known for his meticulous reporting, has popularized the bioterrorism threat in a way that will get the public’s attention with books such as “The Hot Zone” and “The Cobra Event.” Especially when turned into a movie such as “Outbreak.”

Few diseases conjure up as much dread as Ebola hemorrhagic fever. If you’re tired of watching sitcoms and romantic comedies, take a look at “Outbreak,” a 1995 film with a stellar cast. It explores the ethical dilemma of a government that faces the decision whether to annihilate a small town where there is an outbreak of a new airborne mutant of Ebola with a mortality of close to 100% in order to prevent escape into the general population with millions of deaths or just try to contain the virus and hope for the best. The science is a bit speculative but the basic premise is more or less believable. The action, including some of the helicopter flying, is almost unbelievable.
Ebola has been the subject of a number of good books including “Ebola” by William Close MD, father of the actress Glenn Close, who was personal physician to Zaire’s infamous President Mobutu. He was a first-hand witness to the original human outbreak originating in the Belgian Catholic Yambuku Mission Hospital. Of 318 cases, 280 died (88%). The use of unsterilized needles and syringes was blamed for the rapid spread but person-to-person spread also occurred in those with close contact with patients alive or deceased.
Ebola and the related filovirus, Marburg, live in monkeys of various species and only rarely jump into humans. Fortunately. Since mortality is still on the order of 50% or more. Genetically engineering these viruses to produce a bioweapon is a distinct possibility. As we saw with the anthrax attack, there are enough adequately trained scientists lying around to do this if one of them should lose his/her grip on basic humanity. This might be especially true of Russian scientists who worked on the very extensive biological warfare program that went on in the Soviet Union up through the tenures of Gorbachev and Yeltsin and who lost their employment after the national collapse.
If you’re sick of counting sheep at night, you might try counting all the ways some madman might come up with to do us all in. Bugs, nukes, poisons, etc. Or you could think of all the ways chocolate has been made irresistible. As for me . . . .

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.
