devastating pandemics in human history.
In 1346, the population

of Europe, North Africa and the western part of the Middle East was about 100 million. Over the next few years a quarter of them died. They were victims of a new horrible disease that has spread in these areas and it killed most of those infected.
The reason for such a gloomy picture was the bubonic plague. Then it was known as "the great plague" or "the great contagion". Later it was called “Black Death“ . It keeps that name for the present day.
It started in Europe in 1346, and lasted until 1353. Almost one of every three people in Europe got the disease and died.

in just under five years between 1347 and 1352.

Estimated population of Europe from 1000 to 1352:

Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30–60 percent of Europe's population.
People thought that the transmission of the disease from person to person can pass through physical contact or through clothes and bedding. In many cities and country sides have been established quarantine regulations. For example, the British government advised to lock sick in their homes or placed them in a special "plague houses“.

the worst ways to fight the plague. Plague appears

when rats, fleas, and people are in close contact with each other. In finding the people locked up a chance to be bitten by fleas, which transmit plague, or infected through close contact with the other person even more increased.
Spread of plague among the members of one family in the Middle Ages could be very fast if the rats living in the house, was infected. The infected rat, marked with a red dot in the "Day 1", on the 5th day died from the disease. When a rat is dying, fleas leave it, bringing the plague to other rats in the house. By the 10th day all the rats died, and now the fleas move on people, infecting about 75% of them. By the 15th day about half of the people in the house will die of the plague, a quarter will recover, and the quarter will avoid infection.

plague fleas had spread across Europe, that is why

half of Europe died. Spontaneously, appeared a new and much needed in those times profession - rat catcher.

The power of these people on rats explained only as given by devil, and therefore the Church and the Inquisition made short work of ratcathers, contributing the further extinction of people from hunger and plague. People in the Middle Ages knew nothing about bacilli, they just noticed that after the rats plague came to the city, so the rats were considered messengers of disaster and death.

new profession - a plague doctor, whose duty was

the treatment of patients with bubonic plague, or "Black Death", especially during epidemics. Feature of the plague doctor was a protective suit with the original "big-nosed" mask that looked like a bird's beak.

Because of its specific appearance, and also a mystical aura given to them, plague doctors had a significant impact on European culture, as expressed in the appearance of the famous Venetian masks.

million in the 14th century.

The plague lead to a series of religious, social and economic upheavals which had profound effects on the course of European history. It took 150 years for Europe's population to recover. The plague reoccurred occasionally in Europe until the 19th century.

But now there is no plague in the world,
and I hope we will never see such as disease.
