These are pandemics that changed human history

In the field of infectious diseases, an pandemic is the worst scenario. When an epidemic spreads beyond the borders of a country, it is when the disease officially becomes an pandemic

Infectious diseases existed almost always with mankind. malaria, tuberculosis, leprosy, flu, flu, and others were among the best - known pandemics throughout humanity, broadcast Telegragraphy.

The more civilized people became, building cities and creating trade routes with regard to other cities, and making wars with them, the more frequent they became pandemics

The gaps you will see below in the destruction of the human population and changed history forever.

The year 430 BC: Athens

The earliest recorded pandemic occurred during the Peloponnese War. After the disease passed through Libya, Ethiopia, and Egypt, it crossed the Athenian walls, causing two thirds of the population to die.

Symptoms included fever, cough, throat, and bloody blood, irritating skin. The disease considerably weakened the Athenians and was a significant factor in their loss by Spartans.

Year 165 AD: Antonine plague

The southern people became infected with this disease, then the rats infected the Romans, and then the restored troops spread it throughout the Roman Empire. Symptoms included fever, throat pain, diarrhea. This disease continued until about 180 B.C., also taking Emperor Marcus Aurelius as one of the most famous.

Year 250 AD: Cyprus plague

The Cyprus plague caused diarrhea, vomiting, throat pain, fever.

The city's inhabitants fled to the country to escape infection but also spread the disease further. Perhaps beginning in Ethiopia, he passed through North Africa, Rome, then Egypt, and the north.

There were repeated explosions over the next three centuries. In 444 AD, it struck Britain and thwarted efforts to protect against the Scottishs, causing the British to seek help from the Saxons, who would soon control the island.

The year 541 AD: Justinian plague

First appeared in Egypt, spread throughout Palestine and the Byzantine Empire, and then throughout the Mediterranean.

The plague changed the course of the empire, disrupting Emperor Justinian's plans to bring the Roman Empire back and trigger a massive economic struggle. It is also borrowed from the creation of an apocalypse atmosphere that fostered the rapid spread of Christianity.

The repetition of this disease over the next two centuries eventually killed some 50 million people, 26 percent of the world's population.

11th century Leproza

Leprose turned into a pandemic in Europe in the Middle Ages, resulting in the construction of numerous hospitals to accommodate the large number of victims.

A bacterial disease that causes wounds and deformities was believed to be a punishment from God. Already known as Hansen's disease, it still affects tens of thousands of people a year, and it can be fatal if it is not treated with antibiotics.

The year 1350: Black Death

Due to the death of one third of the world's population, the second major outbreak of bubonic plague probably started in Asia and moved west later. Entering Sicily in 1347 AD, it spread rapidly throughout Europe. The dead bodies became so widespread that many remained rotten on earth and created a bad smell in the cities.

England and France were so incapable of pestilence that countries were forced to declare ceasefire during their war. The British feudal system collapsed when the plague changed economic circumstances and demographics. By destroying the population in Greenland, the Vikings lost the strength to carry out the battle against the local population, and their exploration of North America stopped.

Year 1665: London's Great Plague

In another devastating sight, bubonic plague led to the death of 20 percent of London's population. As the number of human deaths grew and mass graveyards appeared, hundreds of thousands of cats and dogs were slaughtered as possible cause of the spread of the disease.

Year 1817: First cholera Pande

The first of seven cholera pandemics over the next 150 years, this wave of tiny intestine infection began in Russia, where one million people died. Spreaded through water and contaminated food, this bacteria passed on to British soldiers, and they brought it to India, where millions more died. Then again British soldiers spread cholera to Spain, Africa, Indonesia, China, Japan, Italy, Germany, and America, where 150,000 people died. A vaccine was created in 1885, but the pandemic continued.

Year 1855: The Plague's Third Pandemia

Starting in China and moving to India and Hong Kong, the bubonic plague claimed 15 million casualties. It was originally spread by fleas.

India faced the most numerous victims, and the epidemic was used as an excuse for oppressive policies that sparked a revolt against the British. Pandemia was considered active until 1960 when the cases fell below a hundred.

Year 1889: Russian flu

The first important flu pandemic started in Siberia and Kazakhstan, travelled to Moscow, and threw up dégaga to Finland and then to Poland, where it moved to the rest of Europe. Until the following year, he had crossed the ocean into North America and Africa. By the end of 1890, 360,000 had died of this flu.

1918: Spanish Grip

The Spanish flu claimed the lives of over 50 million people worldwide.

The 1918 flu was first observed in Europe, the United States, and parts of Asia before it spread rapidly worldwide. At the time, there were no effective drugs or vaccines to treat this killer flu.

But the threat of flu disappeared in the summer of 1919 when most infected people had either developed immunity or died.

1957: Asian flu

Starting in Hong Kong and spreading throughout China, and then in the United States, the Asian flu spread to England, where 14,000 people died over six months. A second wave followed early in 1958, causing the death of more than 1.1 million people in the world, with 116,000 deaths in the United States alone. A vaccine developed, effectively containing pandemic.

1981: H IV / AIDS

First identified in 1981, AIDS destroys one person's immune system, resulting in eventual death from diseases that the body would usually fight. HIV - positives have fever, headache, and lymph nodes expanded after infection. When symptoms leave, the transporters become highly infectious through the blood and hydrogen fluid, and the disease destroys T cells.

AIDS was first observed in homosexual American communities, but it is believed that it was developed by a chimpanzee virus from West Africa in the 1920 ' s. The disease, which spreads through certain body fluids, moved to Haiti in the 1960s, and then to New York and San Francisco in the 1970s.

Treatments have developed to slow down the progress of the disease, but 35 million people worldwide have died of AIDS since its discovery, and a cure has not yet been found.

Year 2003: SARS

First identified in 2003 after several months of cases, the Acuda Breal Syndrome is believed to have begun with bats and later with people in China, followed by 26 other countries, infecting 8,096 people with 774 deaths.

SARS is characterized by respiratory problems, dry coughs, fevers, and headaches and body pain and spreads through respiratory points from coughing and sneezing.

The quarantine efforts proved effective, and by July, the virus has been contained and has not resurfaced since then. China was criticised for trying to suppress information about the virus at the start of the explosion.

Year 2019: COVID-19

On March 11, 2020, the World Health Organization reported that COVID-19 was officially an pandemic after being contained in 114 countries in three months and infected over 111,000 people. And the spread was nowhere near completion.

COVIED-19 was caused by a new coronavirus a new kind of coronavirus that has never been found in humans before. Symptoms include respiratory problems, fevers and coughs, and can lead to pneumonia and death. Like SARS, it has spread through points from the sneeze.

The first reported case in China appeared in the province of Hubei, November 17, 2019. Eight other cases appeared in December with researchers showing an unknown virus.

Without a available vaccine, the virus spread beyond Chinese borders, and by mid - March it had spread globally to almost the entire planet. On February 11, the infection was officially crowned as COVID-19.
