The History of the Flu

The history of influenza is a research paper covering the basic history of influenza. It began with its early history, and why did it never worry about influenza? It also contains three influenza epidemics: the Spain cold in 1918, the Asian cold, the Hong cold, and the fears and grief that remained after them. In addition, this article discusses avian flu and addresses the current threat of the world epidemic of avian influenza. Influenza, an innocent small virus that enters and leaves every year, has always been a part of people's lives.

o Comparison / Contrast: More than 10 months of world destruction, more people died of influenza in Spain, rather than dying from other diseases or historical wars. . . . Influenza is not usually considered a murderer. Instead, it is considered a cumbersome annual virus that is slightly more annoying than a common cold, but less serious. . . When infectious diseases attack society, it is often the most difficult to beat the poorest part of the economy. . . . In contrast, the influenza in Spain is a sick in the air (so it can not be prevented by health and health), it also affects all aspects of the economy.

Among the threats of all new diseases, the occurrence of influenza is most concerned, mainly because of the speed with which influenza can spread and the toxicity it can kill. Recent research has undoubtedly proven Spain's influenza in the year of 1918 with 500 to 100 million deaths and it is the most deadly influenza in the history of mankind originating from birds. Today, a new avian influenza virus with unprecedented death rate, like the H5N1 strain that appeared in Hong Kong in 1997, appears more frequently than ever.

The most epidemic disease in modern history is still inexplicable and there is no reason. Scientists relatively easily identify the cause of the recent influenza outbreak, such as swine flu and avian influenza, and provide a series of trials and counterattacks of vaccines to the international health society. Influenza virus is not particularly complicated; it is just a piece of RNA that goes between animals, humans, and humans other than humans, and it has mutated quickly enough to go beyond any long term immunity. However, a piece of RNA can cause a lot of damage. Spain flu has caused about 50 million deaths (unlike estimates), including 675,000 people in the United States, 40% of the world's population is infected with influenza. A quirky cold, this epidemic is more likely to afflict young people than young people. Scientists judged that this disease caused an overreaction of the immune system, giving young people a powerful immune system to themselves.

After years of strange studies, why are scientists still confused about the 1918 Spanish flu?
