Black Death
This was one of the reasons of death during some centuries.
It started in China in 1331 and then, it was spread across Europe. It
finished in the 18th century.
The Black Death is estimated to have killed 30–60% of Europe's total
population.
The plagues did impact on religion, society and economy.
The accepted theory about the origin of the plague explains that it was
an outbreak caused by a variant of the bacterium Yersinia pestis.
People thought that Jewish people were whose that caused the black
death.
INFECTED PLACES
First, it started in China, in central Asia, then it arrived to Europe. There were a lot of
dead people in Europe. This photo explains all the trajectory of the Black Death and the
dates.
INFECTED PLACES
There are differents theories about where the Black Death started. The most
famous one says that it started in China, Mongolia,and especially in the province
of Hunan.
In 1330 the Black Death started spreading across Western China.
Then the terrible march continue to Cyprus, Sicily and Italy (Winter 1347),
Marseille (January 1348), Paris and the Netherlands in the summer of that year,
by May 1349 Norway, Eastern Europe in 1350 and eventually Russia in 1351.
It started to be one of the main fears of people in Europe, they tried
to escape from their countries, but it didn't work.
Black Death affected London so much.
WHERE IT COMES FROM
The man who practically live with them, had no idea at that time that
rats and fleas that these loaded ,and that they could have something to
do with the disease. The bacterium was called Yersinia Pestis.
This is the
flea that
transmits
Yersinia
Pestis.
SYMPTOMS
After an incubation period of two to eight days, with fever,
headache, chills and general impairment appears suddenly. After a
few hours or days patients notice the presence of bubo, which is
painful to the touch, 1 to 10 cm in diameter, which is usually
located in the groin, armpit or neck areas and can sometimes ooze.
Bubo in groin
SYMPTOMS
There are symptoms of pneumonia too. The pneumonia progresses for 2
to 4 days and may cause respiratory failure and shock. Not be treated in
time, the patient could die.
Black Death was a contagious disease.
The parts of the body that were touched by the black death turns to be
black, or a bubo appears.
CONSEQUENCES
In Europe so many people died because of the plage, field labor decreased and as
consequences the agricultural production went down, too.
By lowering agricultural productivity population was weakened gradually
reaching states of malnutrition and by this way the virus found the lowest
defense systems in humans.
CONSEQUENCES
The sudden scarcity of cheap labor provided a strong incentive for
innovation that helped to bring the end of the Middle Ages. Some
people argue that it caused the Renaissance.
The Black Death killed a third of Europe's population and repeated in
successive waves until 1490, finally coming to kill about 25 million
people. None of the subsequent events reached the severity of the
epidemic of 1348.
It did impact in religion and society too because people that that black
death was Jewish people's fault.
There were some wars too.
PRECAUTIONARY MEASURE IN THE MIDDLE AGES
Among the first measures used in Europe to prevent
contagion was to burn infected clothes or refuse entry of
shipments of tissues in cities. Even in some cities the traveler
allowed entry only after having got rid of the clothes that
brought put, exchanged for other "safe" loan from the city.
They didn't have a lot of ways of how to prevent the
Black Death beacause in that times they were poor, and the
knowledge wasn't like the knowledge of
nowadays.
DOCTORS OF THE BLACK DEATH
The beak is a primitive gas mask, stuffed with substances that make the plague go
away, like perfumes, spices and herbs to purify or neutralizer "bad air". It
performed a dual purpose, hides the cadaverous odor,to stop the possible rupture of
the bubonic pustules. A common belief at the time was that the plague was spread
by birds. So it was believed that wear a mask with beak could avert the terrible
disease.
