Epidemic situation: more than 40 million people died. Influenza is no stranger to human beings. It has existed since the birth of mankind.

In ancient times, because there were no effective drugs, many people could not escape the clutches of death after suffering from influenza. Today, the continuous improvement of scientific level has brought us into a new era of conquering influenza, but there are still many mysteries about influenza that cannot be solved.

In World War I, the outbreak of influenza killed nearly 40 million people. That's Spanish flu, also known as 19 18 flu. The disaster caused by this flu is the most serious in the history of flu, and it is also the plague with the largest number of deaths in history. The incidence rate is about 20% ~ 40%, and the number of deaths is more than 40 million, more than the number of deaths in World War I.. The flu first appeared in Finson Barracks, Kansas, USA. A soldier in the barracks has the flu, but the doctor thinks it's just a common cold. What happened next was unexpected. A few days later, hundreds of people got this "cold". Soon the disease began to spread wildly. In March, the American Expeditionary Force brought the disease to the front of Europe, in April, it spread to the French and British troops, in May, it spread to Italy, Spain, India and other countries, in June, it spread to Britain by the British Expeditionary Force, and then spread to Russia, China, Oceania and other parts of the world. In less than a year, the flu swept the world. 500,000 people died in the United States, 8 million people were sick in Spain, 200,000 people died in England and Wales, and 7 million people died in Mumbai, India. Some Inuit villages are devastated. There are only 80 people in one village, and 73 people died of influenza. 20% of Western Samoans died of influenza 19 18. 19 18 The flu that plagues people presents a strange feature: in the past, the flu always took the lives of the elderly and children, but this time the death curve showed a "W" shape-young people aged 20 to 40 also became the target of this death. Moreover, the source of Spanish influenza and why the morbidity and mortality are so high are also important problems that plague people.
