1817 First Cholera Pandemic:
The first cholera pandemic in 1817, which is considered the trigger for seven cholera pandemics, began as a minor intestinal infection in Russia.
It reached India through British soldiers, causing the deaths of millions of people there as well. Due to the spread of the British Empire and navy, it also reached Spain, Africa, Indonesia, China, Japan, Italy, Germany, and America.
1855 3rd Plague Pandemic:
Beginning in China and spreading to India and Hong Kong, the bubonic plague claimed the lives of 15 million people. It initially spread through fleas during the mining boom in the city of Yunnan, China.
India suffered the highest death toll, and the outbreak sparked waves of rebellion against British colonial rule. The disease persisted intermittently until 1960.
1889 - Russian Flu:
The Russian Flu, the first widespread influenza pandemic in history, began in 1889 in the Russian Empire, centered around Siberia and Kazakhstan.
The Russian Flu, spreading from Finland to Europe, reached America a year later. By 1890, the Russian Flu had caused the deaths of nearly 400,000 people worldwide.
The Spanish flu, which quickly spread across the entire world, actually originated not in Spain but in the state of New Mexico in the U.S.
During World War I, the virus carried by US soldiers deployed to fight in Europe led to the deaths of 50-100 million people within 18 months. This accounted for approximately 15% of the world's population at the time.
1957 Asian Flu:
Starting in Hong Kong and spreading to China, then to America, and eventually to the entire world, the Asian flu of 1957 was one of the greatest nightmares of the 20th century.
As a result of the flu, which caused the deaths of more than 1.1 million people before a vaccine was found and it was brought under control, 116,000 people died in the U.S., and 14,000 in the UK.
1981 HIV – AIDS:
For the first time in world history, the HIV - AIDS virus, detected in 1981, destroys the immune system, leading to the death of the patient even with the slightest illness.
The disease, first observed in homosexual American groups, has led to the deaths of 35 million people since the first case, and a cure has not yet been found.
The coronavirus, first observed in January 2020 in the city of Wuhan, China, rapidly spread worldwide, leading to an international lockdown.
On March 13, 2020, Europe became the epicenter of the virus. On March 26, the highest increase in cases was observed in the U.S. The world was severely affected by this pandemic.
