The king who killed 50 million also confessed.
● It's a mutation of avian influenza ● It specifically attacks young adults ● Ceng Bo went to China.
In the First World War, mankind fell into internecine warfare, and hundreds of thousands of people died, which became a catastrophe in human history. However, at the end of the disaster, an outbreak of influenza killed nearly 50 million people, which was the Spanish flu that people smelled in the last century, or 19 18 flu. This year1October 5 10, scientists discovered that Spanish influenza is actually a variant of avian influenza.
The American expeditionary force brought germs to Europe.
During the First World War, the world was in great turmoil, reorganization and popular disorder. It was against this background that the Spanish flu occurred. At that time, Spain was the first to announce the flu epidemic, so it was called Spanish flu. Because this flu caused a worldwide epidemic, it happened in 19 18, so it is also called 19 18 flu.
The flu first appeared in February 2008 in Finson Barracks, Kansas, USA. 19 18 March 1 1 Before lunch, a soldier in the barracks felt fever, sore throat and headache, so he went to the military hospital to see a doctor. The doctor thinks he has a common cold. However, what happened next was unexpected: by noon, more than1000 soldiers had similar symptoms. A few days later, on the weekend, more than 500 "cold" patients came to this military camp. It soon spread to Detroit and other three cities → the American Expeditionary Force took it to the front line of Europe by boat in March → the French army in April, and then troops from Britain and other countries → Italy, Spain, Germany, Africa, Mumbai and Golgotha in India in May → the British Expeditionary Force spread to Britain in June, and then to Russia, Asia, China, the Philippines, Oceania and New Zealand →1966.
The disaster caused by this influenza is the most serious in the history of influenza epidemic, and it is also the plague with the largest number of deaths in history. It is estimated that the number of patients worldwide exceeds 500 million, the incidence rate is about 20% ~ 40%, and the number of deaths exceeds 40 million, more than the total number of deaths in World War I.. The flu shows quite strange characteristics. In the past, the flu always killed the elderly and children, but this time the death curve was "W"-young people aged 20 to 40 also became the target of this death.

The king of Spain was not spared.
The death toll in America is 500,000. On June 65+1October 65,438+00, 438, 759 people died of influenza in Philadelphia, and 8 million people fell ill in Spain, including King Alfonso III. One-third of the citizens in Madrid were infected, some government departments were forced to close, and trams were shut down. George V of Britain was not spared. The death toll in England and Wales reached 200 thousand, and the royal fleet could not enter the sea for three weeks, which affected the operation. 7 million people died in Mumbai, India; Some Inuit villages were devastated. In one village, 80 people died of influenza and 73 people died. 20% of Western Samoans died of influenza. In many countries, corpses pile up into mountains; There are no passengers on the tram in Ottawa, Canada; Schools, dance halls and cinemas have no lights, and swimming pools and bowling alleys are empty; Due to the lack of coffins, a small town in South Africa was hastily buried with blankets, with funerals all over the streets during the day and ambulances shuttling at night.
19 18 Spanish influenza also spread to China, from Guangzhou to the northeast in March, and from Shanghai to Sichuan, with a wide spread. More than half of the police in Beiping are sick, 40% of people in Harbin are infected, schools are closed and shops are closed. There have also been two waves of popularity in Shanghai.
Spanish flu is a variant of avian flu.
But where did the Spanish flu come from? Why is the morbidity and mortality so high? Why are these series of problems mainly attacking young people and puzzling people for nearly a century? Only on June 5, 2008, scientists found that the disease that killed many people on June 5438+09 18 was avian flu. According to the BBC, research by American scientists shows that the Spanish influenza virus that killed 50 million people in1918-19 probably originated from birds. American scientists published an article in the journal Nature, saying that they found the genetic variation of the virus 19 18, which is the same as the avian influenza virus H5N 1 that appears in Asia now. Another research group in the United States also published an article in the journal Science. They have successfully reproduced the virus of 19 18 in mice. Some genetic codes they found will help to predict and respond to the next influenza epidemic.
