Cat in Los Alamos County diagnosed with plague - Santa Fe New Mexican Posted: 11 Feb 2021 12:00 AM PST A cat in Los Alamos County has been diagnosed with the plague, the state's first case this year, the New Mexico Department of Health announced Thursday. The state released little information, other than to say the cat became ill in late January and is recovering after receiving treatment. Health officials will conduct an investigation to ensure the cat didn't spread the disease to family members or neighbors. "Even in the midst of a global pandemic, other diseases still occur in New Mexico, and there are steps people can take to keep themselves and their pets safe," Dr. Tracie Collins, state health secretary-designate, said in a statement. The plague is often transmitted through flea bites but can also be passed via rodents, wildlife and pets. In August, a Rio Arriba County man died of the plague, and in July, a Santa Fe County man was diagnosed with the disease. Health officials also detected the plague in a dog and cat last year, both in Santa Fe County. In 2019, the state had one case of the plague: a 72-year-old Torrance County man. Symptoms of the plague include fever, chills and headaches. There also can be swelling in the groin, armpit or neck. To prevent the plague: u Avoid sick or dead rodents and rabbits as well as their nests and burrows. u Prevent pets from roaming and hunting. u Clean up areas near your home where rodents could live, such as woodpiles, brush and abandoned vehicles. u Have sick pets examined promptly by a veterinarian. u See your doctor about any unexplained illness involving a sudden and severe fever. u Move hay, wood and compost piles as far as possible from your home. u Don't leave your pet's food and water where rodents and wildlife can get to it.

What Really Caused the Black Death: Anthrax or Celestial Bodies? - The Great Courses Daily News Posted: 22 Feb 2021 05:55 AM PST By Dorsey Armstrong, Ph.D., Purdue University For centuries a bubonic plague epidemic was considered to be the prime cause of the Black Death. Based on inconsistencies and divergences on the cause of what ultimately killed half of Western Europe's population, scientists started reexamining the evidence with renewed interest in modern times and came up with new theories. The Black Death killed half the population of Western Europe. (Image: Wellcome Images/CC BY SA/4.0/Public domain) A Radical Revision In 1984, an epidemiologist named Graham Twigg published what at the time was considered a radical rethinking of the causes of the Black Death. He argued that most deaths in the medieval epidemics were not caused by the plague at all but, in fact, were due to exposure to anthrax. Anthrax is a bacillus—like Yersinia Pestis— and it is found to be naturally occurring on every continent, including Antarctica. Infection usually occurs when grazing animals inhale the Bacillus anthracis spores. If we consume meat from infected animals, the infection transfers to humans. Humans can also contract anthrax if they directly come in contact with it in nature. Anthrax spores are extremely long-lasting and hardy. They have been discovered in soil covering an animal that died of Anthrax infection 70 years after the fact. This is a transcript from the video series The Black Death: The World's Most Devastating Plague. Watch it now, on The Great Courses Plus. Anthrax as the Cause of the Outbreak If a person inhales anthrax spores, they usually have some flu-like symptoms for a few days, then experience severe pneumonia and respiratory collapse—all familiar symptoms of the pneumonic form of plague. Also, if a piece of infected meat is consumed, the individual will experience serious GI issues and end up vomiting blood, again symptoms associated with all three forms of plague. And, even more to the point, boils and lesions often show up on the bodies of those infected with anthrax. Historically, it's estimated that fatality rates for anthrax were around 85 percent.

In modern times, if anthrax is diagnosed and treated quickly, the fatality rate is closer to 45 percent. Considering that this pathogen can survive even decades after the death of its host as well as the lack of proper burial for diseased animals in the Middle Ages, the theory of anthrax as the underlying cause of the Black Death appears logical. This hypothesis can also explain why the plague would flare up every decade or so after its initial wave swept through the medieval world. Learn more about later plague outbreaks: 1353-1666. Murrain Contribution Historian Norman Cantor points out that anthrax spores have been found in a mass grave, dating from the Middle Ages in Scotland. There's evidence that meat from slaughtered murrain-infected cattle was sold in villages in England shortly before the first big outbreak there in 1348. There are some scholars who have found much that is persuasive about this theory. But they have more cautiously proposed that while anthrax may be the cause, it would be safer and more accurate to argue that some sort of cattle and/or sheep murrain may have been a contributor. Murrain, originally and appropriately, is a medieval word that at first just meant death, but it gradually underwent linguistic specialization and came to mean any disease that affected cattle and sheep. Death from Outer Space There are other interesting and even terrifying theories about the origin of the plague. One theory argues that the Black Death originated from outer space. This theory was first proposed in 1979 by Fred Hoyle, a Cambridge University astrophysicist, and Nalin Chandra Wickramasinghe in their co-authored book, Diseases from Space. They believe that Darwin's theory of evolution is correct up to a point, but the elements indigenous to Earth are not enough to contribute to the development of flora and fauna on our planet. For life to flourish on Earth, some external or exogenous elements were essential. Based on the panspermia hypothesis, the seeds of life exist all throughout the universe, and those seeds move through the galaxies as parts of comets, asteroids, and other celestial objects. Some of them carry pathogens, and when they crash into a planet like Earth, we have what Hoyle and Wickramasinghe call vertical transmission. The Horizontal Transmission of a Disease Hoyle and Wickramasinghe argue that the bubonic plague may have been vertically transmitted from space. (Image: Vadim Sadovski/Shutterstock) Once that disease establishes a foothold on Earth and finds some reservoirs or hosts it can hang out in, then horizontal transmission—from animal to animal or person to person or animal to person—can occur. They argue that the bubonic plague appears to be a likely candidate for a disease that was vertically transmitted from space. They claim that this explains why the plague appeared in the 6th century, then again in the 14th, and once more in the 19th, with substantial gaps in between the outbreaks.

Just as planetary objects like the Halley's Comet pass by Earth in regular intervals, there is a possibility that unnoticed comet-like objects, rained down the plague bacteria and found its most willing hosts in black rats. Indeed, while the authors acknowledge the role that the black rat played in the outbreak of the Black Death, they also are quick to point out the flaws in the theory that these rodents were the main vehicle of transmission: What remarkable rats they were, to have crossed the sea and to have marched into remote English villages, and yet to have effectively bypassed the cities of Milan, Liège and Nuremberg. There was no marching army of plague-stricken rats. The rats died in the places where they originally were. The idea that life on Earth—at least some of it—may have originated elsewhere has some scientific merit. After all, there is substantial meteoric traffic among the inner planets, and there are plenty of microbes that could survive the journey through space. However simultaneously, the specifics of Hoyle and Wickramasinghe's theory is considered very fringe by the scientific community at large, and pretty much every mainstream scientist is of the view that the theory doesn't really hold water and certainly can't be proved. Common Questions about the Causes of the Black Death Q: According to epidemiologist Graham Twigg what was the cause of the Black Death? Graham Twigg argued that the Black Death in the medieval times was not caused by the plague at all but, in fact, was due to exposure to anthrax. Q: Why deaths caused by anthrax can be misdiagnosed as plague-induced? If a person inhales anthrax spores, they usually have flu-like symptoms for a few days, then experience severe pneumonia and respiratory collapse—all familiar symptoms of the pneumonic form of plague. Moreover, if a piece of infected meat is consumed, the individual will experience serious GI issues and end up vomiting blood, again symptoms associated with all three forms of the plague. Q: Based on the idea of vertical transmission, how was Yersinia Pestis introduced on Earth? Just as planetary objects like the Halley's Comet pass by Earth in regular intervals, there is a possibility that unnoticed comet-like objects, rained down the plague bacteria and found its most willing hosts in black rats. This is how Yersinia Pestis was introduced on earth.
