Article author Ni Fang 6

Qiu Dong is the tall hair season of flu. This year because have avian flu, at present becomes more sensitive. I should not answer flu previously thing, these days I am interviewed in what make this field, check the discovery when the data, flu is to comparative actually quite terrible, want dreariness than war, AIDS much, it is fierce " homicide " prime criminal. And current and foregone catch a person the earliest " avian flu " , be 1918 " Spanish flu " the discovery on the dead‘s skeleton.

The mankind has account " homicide flu " erupt greatly, have 6 times at least. Be in for the first time the Christian era 9 centuries; Be about the 2nd times to end in period of the First World War when, came 1918 namely 1919, be called " Spanish flu " ; Came the 3rd 1957 1958, be called " Asian flu " ; Came the 4th times 1968 1969, be called " Hong Kong flu " ; Came the 5th 1977 1978; The 6th, namely at present.


The dead number that causes, count the 2nd times most, be as high as 21 million person, say 50 million, exceeded the dead number of the the First World War. The 3rd a few is much, but also exceeded 150 more than person. After this is carried as what method of medical level, precaution, heavy visual range spends do, dead number is smaller and smaller. "Hong Kong flu " died tens of thousands of person, the 5th reach current global flu, although erupt range is wide, but dead number is reduced greatly.



The 2nd " Spanish flu " it is global, the person that dies because of Spain is most, friend name. Be in only 1918, the number that Spain dies because of flu was achieved 8 million. At that time, homicide flu spreads all over the whole world, europe of sweep anything away, everybody dread Wei, the color that talk changes.

Fierce to what degree, the work in the same placing still has on the road that go to work say to have laugh, somebody sufferred from flu, still do not have when come off work to die. Have a classic dead example: 4 Spain make an appointment to play a card together after feminine dinner, play second half night, terrible situation appeared, they are abrupt had a cold, did not arrive day break, among them 3 women are dead.

Write the mankind as special case the homicide flu on warlike history, it is Spanish flu. The autumn 1918, world big the First World War ends soon, american soldier attended Europe to fight, the Entente countries strikes back German war is close to a victory. At that time, stay in the soldiers in entrenchment, feel have sth hoped for and likely to happen, come home have period. Which know, "Homicide flu " sneak attack they, inside very short time, have death of many 40 thousand U.S. Army.

At that time, on the ave of a few countries of European, it is a body everywhere, it is to have not enough time bury, 2 it is living person fears, hide far. The government is obliged to make convict by force appropriative bury (burn) cadaver person, some bodies by be thrown directly continuously in the great river, go along with current.


Strange is, "Spanish flu " disappeared indescribably again however 1919. Virus is like homicide really ghostliness and same, the person does not know ghost not to become aware, when coming, did not adumbrate, go mysteriously also.


"Spanish flu " be not seminary at Spain, say to appear in the barback that appears in American Kansan at first, time was 1918 early spring; Another say to think to result from Asia, the Asia is the base camp of cold virus, the mutation of gene of a kind of virus is brought about. At that time, "Spanish flu " in India very atrocious, european mortality is as high as 2.5 % , be general flu 20 to 25 times, and Indian mortality is 5% .

Many medical experts think by accident at that time " Spanish flu " , it is the disaster that the war causes, did not cause take seriously, did not retain the vivid put oneself in another‘s position of virus, consider in order to offer the following medical to use. Later, as " homicide flu " appear for many times, medical expert just begins to take seriously rise, right 1918 " Spanish flu " begin to consider.


Medical expert suspects, 1918 " Spanish flu " can be extremely fowl or avian infect the mankind, namely alleged " avian flu " . And inspire this kind of viewpoint, it is little scope that took the place of to erupt in Chinese Hong Kong 1997 " homicide flu " . Most what die because of this kind of flu first is 10 years old of little girls, classics medicine is anatomized detect, discovery has a kind of strange virus that the name is H5Nl inside her body. Later, medical expert discovered this kind of virus on gallinaceous body -- " avian flu " , just begin to be realised truly.

Many people still think now, the probability of virus of human infection avian flu is very small. Actually, medical bound is early admit this kind of viewpoint, the time that avian flu virus appears is earlier than person flu virus, person flu virus is mutate by avian flu virus and come. But most bloodcurdling " Spanish flu " , does avian flu virus mutate? Ever was one of medical mystery groups that have be concerned about most.


To make clear " Spanish flu " the real features of virus, break interpret virus code, the epidemiology expert cudgel one‘s brains for on the world, not hesitate even go digging the dead skeleton, and took the place of early to begin to dig 1950.

Institute of pathology of U.S. Army army is called Dabenboge (Taubenberger) M.d. , took the lead in observing this is planted virus. It is in the archives of the institute, he discovered accidentally in those days pathology section of the dead, duplicate the gene code that gave virus. This is a lung example of 21 years old of soldiers, dabenboge found 9 paragraphs from which " Spanish flu " the ribonucleic acid of virus (RNA) " fragment " .

Dabenboge discovers, "Spanish flu " virus and swine flu virus have similar place, it is H1N1 model. Dabenboge‘s paper, published in the United States 1997 " science " on the magazine, caused the whole world the attention of relevant medicine expert.

Studying all the time 1918 " Spanish flu " the virus, pathology home that is called John Huerting, because this came,study inspiration. In the cemetery that he gets on stealthily from one small town, gouge in those days " Spanish flu " the patient‘s skeleton, got virus sample book smoothly. Very regrettablly, because time is too long, virus dies already, cannot make its renascent.

Hu Erting did not abandon, the layer of permanent frozen earth that he is in Alaska later, send disinter again a body. This is the body of a woman that is called Ruth, as a result of before one‘s death fat, have adipose protection, her lung actually in good condition nondestructive, hu Erting cuts this lung after falling, brought Dabenboge.



World flu authority overcame filar Dr. Di to also take similar step, through searching in those days the dead‘s body, will consider " homicide virus " . Ke Sidi and her staff comes to a Norwegian island, because there is layer of permanent frozen earth on the island, have clear account again, there are 7 to die at on the hillside inside the island " Spanish flu " collier. These 7 colliers, inside a few days of time in succession gone, at that time by nearby bury.

Very regretful, these bodies are not to be buried below layer of permanent frozen earth, be in however superstratum, the body when gouge had decayed. Fortunately, have a cankered rate inferior, obtained needs parenchyma. After medical expert made an analysis to parenchyma, discover surprisingly, the mankind dies history on the fiercest " Spanish flu " , its virus extremely resemble avian often suffer from " avian flu " .

2001, australian scientist discovers further, "Spanish flu " a paragraph of encode that is swine flu virus actually " grafting " arrived in the RNA of human flu virus. Again later, medical expert actually will " Spanish flu " virus is renascent, this message sees the England that published on October 6, 2005 " natural " on the magazine.

But, although medical expert defeats interpret " Spanish flu " virus gene, but how does virus mutate, how to infect person to go up again, most begin from where first, still be the mystery that did not solve. . . .
