Crime Scene Cleanup School Science

The Angel of Death

Crime scene cleanup school students must have some knowledge of bloodborne pathogens. They must also know about other pathogens brought to humanity by vectors, like the rats in Medieval Europe. Upon these rats survived fleas, and within these files grew the deadly bubonic plague virus. The "Black death" wasn't coined until 1832 as it turns out. Suffice it to say that "Angel of death" served as the most common phrase for common people trying to understand this great threat to their lives and the lives of those around them.

Interestingly, the rats would one day receive blame for the plague, but the scientific method would show not the rats, but the rats' fleas carried the virus. The plague now carries the ominous title of a vector-borne disease.

Crime scene cleanup school biohazard cleanup practitioners learn that the black plague became one of humanity's oldest diseases and has become one of our newest medical mysteries.

It still remains hard for most people to understand how something so tiny as a bacterium in the role of a Grim Reaper to kill millions of people during the Middle Ages throughout Europe. We've had vectorborne diseases every sense our inception as a species. But it's not so with crowd born diseases.

Keep these ideas in mind because this crime scene cleanup school offers tests on this very subject and bloodborne pathogens as well.
Many types of microorganisms depend on multiple vectors to spread their type. We find this occurring in malaria and dengue fever and each may be carried by more than one species of mosquitoes. The Zeka virus now joins the number of vector viruses that recur through blood-borne transmissions once it enters the human bloodstream.

Change and Virulence

These vectorborne microbes change over time and their changes occur differently than that found in other microbes. As long as her primary host remains healthy they do not need humanity. In cases of extreme virulence, it's better that the host, the victim, remain healthy for as long as possible to help spread the disease further and faster to more host. It's when a virus kills its host quickly that the virus fails to spread itself and threaten self extinction.

This would help to explain the HIV virus dormancy for up to 10 years when infected many of its human hosts.

Prior to the emergence of the plague, Europe was basking in one of the most fruitful, productive, and disease-free periods in its history
For reasons we still don’t understand, temperatures were much warmer from about 950 AD to 1250 AD

During this Medieval Warm Period, European populations grew very rapidly
By the Twelfth Century, the population of Europe had tripled

They called it the “monde plein”, the full world – and it was the time when the great cathedrals were built
The warm period led up to the Renaissance, the great flowering of European culture

But this warm spell was followed by an extended period of damp, chilly weather called the Little Ice Age, which lasted for nearly five hundred years, from about 1350 to 1850
Very few people have heard of the Little Ice Age, although it was one of the most important events in human history

America is a nation of beer drinkers, for example, because our ancestors could’t grow grapes in Northern Europe during the Little Ice Age!
Among the many cultural landmarks it led to were sexual privacy, the Stradivarius violin, and the French Revolution…

In the end, it doesn't matter to a vector whether or not it's host suffers bedridden and in agony. What matters is that the host survives to spread the vectors kind into host. Such diseases are like timely Angels of death as they swooped down from someplace unseen. They lead to nightmares for many of their victims will crushing the victim's hopes.

Before the plague's arrival, Europe experienced a fruitful and productive, free of disease. During this warm. Europe's population grew rapidly as it has in the 20th century. European population of the 12th-century grew by three times its 11th-century numerical growth. Keep in mind that the warm spell led to Chile whether that we now call a "Little Ice Age." During this time that lasted for over 500 years, from 1350 to 1850, life became tough for humanity throughout Europe. Famine leading to starvation and illness was quite common among commoners as well as the ruling classes. The only reason that we turn to beer from wind is that during the Ice Age Europeans cannot grow grapes.

Sexual privacy became possible during cold weather, which led to chimneys and flues that could share a fireplace on more than one floor. Traditionally (and now common) communal hearths

Social classes became more solidly stratified as a definite upstairs and downstairs leveling occurred between servants and masters. For music lovers this one cold. Upon the earth led to treaties producing wood with more greatly packed cells and this in turn led to the fantastic sounds produced by the Stradivarius violin. The French Revolution arose, in part, because famine helped to fuel social unrest among the have-nots and the have nots The French ruling class let the masses starve. "Let them eat cake" became part of written history throughout the world in terms of class conflict.

During this climatic climate change. Temperatures dropped 40 to 50°F allowing for increased snow cover. Glaciers moved south at a rapid rate just as they move north today because of climate change created by fossil fuel burning following the Industrial Revolution. We don't fully understand what caused the climate change to colder weather patterns, but we do know that the best theory is during warm periods snow and ice melt and change the density of seawater in the North Atlantic. This in turn inputs freshwater more rapidly and thereby slows down and even stops the oceanic conveyor belt. The oceanic conveyor belt creates currents that redistribute equilateral heat to the polls. Warmer water near the poles means warning polls as today; therefore, reverse this condition and refine colder periods. Today we wonder what happened to crime scene cleanup in terms of climate deniers.

What does matter is that thousands of villages disappeared from the map during this cold. During the cold. Because grain did not fully ripen starvation increase. With starvation increasing the human tendency toward poor health increased as immune systems failed. Human body must have a set number of calories to remain healthy and when children and adults don't have enough calories for protein and carbohydrates, the more successful people to diseases like the black plague. Security became an issue as well as crime scene cleanup issues as Germany alone lost 40,000 towns. This occurred between 1350 and 1450 and guards were posted on Dallas throughout the Rhineland, and villagers cut down hanging corpses for food.

Because the expense of wheat and grew, and wheat had been Europe staple food just like rice in Asia, natural catastrophes began to mount from the fickle weather. Over 100,000 people drowned in All Saints Flood in Holland.

Social and political structures broke down as people sought answers from God. Many have lost their faith and believe that God had abandoned them while neither priests nor kings could help stop the slide in ideological supports for the church. The world seem to be sliding into room one and stereotyping people for scapegoats, like the Jews, or witches, or vagabonds, or anyone in authority became targets for hatred and bigotry. If all this wasn't enough, the hundred years war would envelop the continent.

One historian by the name of Barbara Tuchman wrote in her classic A Distant Mirror: The Calamitous 14 Century, makes note how this period of human history developed into one of the worst periods of human history. Now we must keep in mind that she's writing about Europe and not Asia. We must remember that Asia has its own history separate from Europe and surely the masses in Asia had suffered as well.

Because the bubonic plague is a vectorborne disease, it carried Oriental rat fleas with it. These persist in the wild and many species of rodents and even today we must fear their return to our locations. The sanction killer threatens us with new varieties of mutated vectorborne diseases.

We know that in the Plague of Justinian in 541 A.D., for over 200 years the Roman Empire suffered as the plague burned its way from Egypt through Alexandria to the rest of the world. Over 10,000 lives were lost in Byzantium during any one day. At its worse, over 300,000 victims fell to its powers in one year. That's 1/4 of the city's population. Over 100 million people would die in the Eastern and Western Holy Roman Empire. Is it any wonder that people question the God at the time because of death was everywhere. The faithful will remain faithful because they had seen the greater light, it seems. Meanwhile, those should last faith cried out for a greater crime scene cleanup practice to save them from their unknown predator.

Procopius wrote that there were so few grave diggers that local authorities had to find a new way to dispose of the cadavers as quickly and efficiently as possible because of the stinking many flies that gathered in the remaining living space. To this end they remove roofs from towers affords and dropped the corpses within the structures and then replace the roofs. Great send plague land as well as so much depravity and general licentiousness grew like Sodom and Gamora; it seemed as though the disease had left only the most wicked and there were no crimes in cleanup practitioners available.

Today many writers and scholars believe that the European Black death began in central Asia or China around 1320 to 1340. Many Chinese died of the disease before it spread to India and Africa along the silk Road and Ocean trade routes. During this terrible time Europe sunset expect in millions enjoyed the last of their warm spell fruits. The world seem to have gone into a dark shadow is people remembered the Roman Empire had failed. Trade and travel made its way through Africa and India to the Far East allowing for Biohazards to spread throughout new lands.

New procedures would cross the map of the unknown world by the thousands seeking to return Jesus to Jerusalem. They made great use of the old silk Road as did Marco Polo in 1271. The Mongol hordes straddled Eurasia, from India to the Black Sea. Exotic trade goods flowed from Cathay to Constantinople.

During the siege of Caffa, the Khan's Turkey's mercenaries knew enough to use plague-written corpses as a form of biological warfare. The through these rotting pieces of biohazard material over the city's walls hoping that the city's residents would remove them without considering biohazard cleanup protocols. Fortunately for the Turkish mercenaries the residents knew little about biohazard cleanup because they had not been to our crime scene cleanup school. This type of germ warfare would continue throughout the ages and threatens us to this day.

The Genoese controlled Caffa during this period of time and the residents fled in terror. As a result he carried the disease back to Sicily, Genoa, Venice, and other Mediterranean ports of entry. It took about three years for the plague to cover all of Europe and north Africa and finally reach Britain in 1348. So we know from this one act of biological warfare the germ spread throughout Europe. What does this mean for today when we have global climate change because of global warming and nationstates setting up to do global war? Will we see worldwide biological induced germ warfare and the need for professional biohazard cleanup practitioners to act as soldiers?

Many villagers crowded into the cities in the hope of finding shelter and security from the disease and marauders ransacking the land as death and destruction preceded them. As a result sewage problems arose because of growing garbage dumps, sewage pouring into main streets, and rats spreading throughout the cities. The Black death had found European populations dumb, ignorant, and willing host for the spread of the plague. It was not unusual for a city's population to drop anywhere from 40 to 60%. Somewhere between 75 to 100 million people died in the 14th century as the black plague spread throughout Europe.

W and flowing throughout Europe for over 300 years the black plague would reach London, where it became known as the great plague of London between 1665 and 1666. Daniel Defoe and Samuel Pepes became known as the chronic pullers for this spread of the disease. Somewhere between 70,000 and 100,000 Londoners died from the disease. This is a great number considering that it represents a huge percentage of the total London population.

As in the case of the Turks throwing cadavers infested by the black plague into the streets of Genoa, London would not require crime scene cleanup practitioners, but biohazard cleanup practitioners.

London's dogs and cats were suspected of carrying the plague and as a result 40,000 dogs and over 200,000 cats died as London's residents with superstition and ignorance guide their actions. Ironically the dogs and cats would have helped to keep the rat population in check, but crime scene cleanup schools were in short supply during those days and there's no way for people to learn the germ theory of disease as a result. We learn to discern three distinct forms of this plague, and each one became more terrible than the one before. The bubonic plague is known as a common form of the plague, while the pneumonic, and septicemic each brought their own form of horror. Today we can keep these terrible forms of the plague in check with our powerful antibiotics and vaccines. Woe to those who do not believe in these medical science remedies to natures unseeing creatures.

The black plague in facts humanity by entering the lymphatic system which serves as an important part of the immune system. It takes from 2 to 5 days for the infection to grow with fever, chills, muscle aches, and even headaches. Lymph glands located in the groin, neck, and armpits swell to huge shapes causing much discomfort. We use the term plague buboes to describe these terrible and grotesque misshapen tumor like growths.

Delirium, convulsions and then death usually follow infection and this resulted in the 40 to 60% death rate taking about 2 to 8 days when the black plague is left untreated. Of course, those unfortunate enough to fall victim to the black plague experience great pain from their misshapen lymphatic glands. Their skin decomposes while they're still alive. Even the psychological trauma experienced as one sees their very skin decomposes must add to their discomfort and dismay.

The pneumonic plague also spreads to the lungs and maybe even become airborne through an aerosol spread as patients cough and sneeze. In the medieval days we were not aware that airborne pathogens existed and it may be that many millions died because they were not aware of the importance of covering one sneezes and coughs. Remember that the bacterial toxins interfere with the blood clotting process and as a result victims bleed to death. Of course this type of biohazard cleanup actually involves much blood cleanup when plague victims die and are quickly removed.

Nine such a horrible death over a period of almost a week in some cases would lead to victims of moans escalating this sounds well beyond humanities normal sounds created during moments of great pain. The poet Petrarch asks:
“Is it possible that posterity can believe these things? For we, who have seen them, can hardly believe them.”

Just as today quack cures crew and people sold off everything from cat urine to dog feces as "known cures" to the black plague. The best advice was to avoid direct physical contact with the infected. Doctors dressed in a morbid "beak doctor" uniform as a type of biohazard cleanup suit. Dried herbs were Nearby and people often ensured that the children only left home after their pockets were stuffed full of these herbs and flowers. In London a famous plague ballad would become the tune often saying by children playing outdoors:

Ring around the rosey,
A pocketful of posies,
ashes, ashes,
We all fall down!

It was a great time for thieves and looters with a willingness to enter homes of those stricken by the black plague. They rejoiced until they too caught the disease in many cases. This was a time of great plundering of the dead. People hoarded and others profiteering at the expense of the community and neighbors. Healers and priests were scared as they too died off over ministering to the sick until called upon by the angel of death.

The dead were carried away by endless trains of carts to mass graves serving the needs of hundreds of dead. Church bells rang throughout the day as numerous souls were sent to heaven. Families of five children buried five children in a single day and as they did so they believed they were really living in the end of the world, for the apocalypse had arrived. Graves were often so shallow the dog scraped out the corpses devoured them. This rude type of biohazard cleanup would not appeal to us today. Great pits were dug to Barry hundreds of the time. One issue became whether or not enough grave diggers could be found to do these pits.

Has the plague finally when it's way many people lost their faith. For others, they believe that God's grace and save them from death and that they would become better condition, humble, virtuous, and Catholic. They would guard against inequity and sins. They would show their love and charity while acting saintly towards others. But just about the time the black plague when it's way people began to act to the contrary. They forgot the past as though it never had been. They acted more shamefully and disordered lives than they had before. They sought out the sin of gluttony while taking part in feasting caverns. They sought out the delicacies of food and played games of hazard while loudly eliciting the pleasures of the body.


The poor sought out costly garments worn by the newly dead rich and went about in their new garments.

A Third Plague Pandemic

1/3 pandemic in 1890 spread from China and killed 15 million lives. This did not involve crime scene cleanup of course, but did involve biohazard cleanup on a broad scale. The plague circle the globe this time it made its way into the United States the Chinese workers in the San Francisco area. Even to this day this deadly plague resides in the American Southwest. But today we have it under control thanks to medical science. A Japanese team headed by Dr. Shibasaburo Kitasato took an early lead
But a young doctor named Alexander Yersin was the first to confront mankind’s medieval nemesis

Your send studying in Paris and became a French citizen, but kept his Swiss citizenship. While doing an autopsy on a rabies victim to cut himself and rushed off to the nearby Pasteur Institute and asked Pasteur to helping. Pasteur asked his friend Emile Roux to give Yersin the no one rabies vaccine and help the young man remain alive. As a result past year and the young Yersin remain friends.

Yersin continued to work at the Institute, teaching a class in microbiology, and when plague struck in China, Pasteur asked Yersin to investigate
Pasteur persuaded the French authorities to send Yersin to Hong Kong in 1894

But the British ruled Hong Kong, and they supported Dr. Kitasato, a colleague of Robert Koch
Kitasato had all the advantages – a team of Japanese specialists, a gleaming and well-stocked laboratory, the latest Zeiss microscopes…

When Yersin arrived at the Hong Kong city hospital, he found that every door was closed
The hospital director refused to give him space for a laboratory, and would’t even let him take samples from the hospital’s plague victims!

After pleading with the governor of Hong Kong, Yersin forced the hospital director to give him an office, which turned out to be a small table in a corner of a dimly-lit hallway, with barely enough room for a microscope and a few rat cages

Yersin then went to a by the name of Father Vigano. Vigano allowed Yersin to place a grass hut right next to the hospital. In this hut Yersin did medical science.

Yersin then bribed two British soldiers with duties in the hospital morgue. They supplied plague buboes on corpses to the young, dedicated doctor. He then tested his serums on guinea pigs and found a cure. In a sense we find the spirit of crime scene cleanup in Yersin's work, then.

He named the bacterium Pasteurella pestis, though it was later renamed Yersinia pestis, in his honor (Kitasato is recognized as its codiscoverer)

Yersin continued to work night and day on the plague, and soon discovered an effective antiserum
He later opened a branch of the Pasteur Institute in Vietnam, which became his adopted country, and devoted himself to the health and welfare of the Vietnamese people

He remained in Vietnam and helped the Vietnamese grow rubber trees. He worked along with Roux and discovered a diphtheria toxin while becoming a hero to the Vietnamese. In Yersin we find a biohazard cleanup practitioner worthy of our crime scene cleanup school pages..

We're often reminded how crime scene cleanup companies mislead the public by proclaiming the blood and death orders are so dangerous. We know otherwise here at crime scene cleanup school because we know that Pharaoh's priests survived to embalm many thousands of decomposing human bodies, Sun Gods and mere mortals.

Vector-borne means many epidemics arise from diseases like typhus, malaria, and dengue fever. Any organism that carries a microorganism, microbe, that causes a disease includes vector-borne diseases. Anthropoids carry most vector-borne diseases. These include flies, Fleas, ticks, lice, and mosquitoes. Some of these diseases rely on multiple vectors. They survive without a secondary host, which crowd-borne diseases must rely upon.
