The source of the virus can only be traced to scientists |
The time limit given by the president is approaching, and the US intelligence agency's new crown virus traceability investigation report will soon come out
.
At this moment, curiosity is a little impatient, wanting to see what can be traced back to the omnipotent CIA traceability
Common sense tells us that the basis of virus traceability is the discovery of evidence through scientific research.
This is the work of scientists.
Others want to replace it? There is no such ability
.
The history of the world's great plague tells us that scientists are also struggling to trace the source of the virus.
They rely on scientific evidence to guess, sometimes they guess right, most of the time they don’t, so the negation of such denials will lock the chain of scientific evidence bit by bit, and finally point to the only truth..
The concept of traceability came after modern science
.
Scientific intervention has become a watershed for understanding the great plague, such as the Black Death that swept Europe many times from the middle of the 14th century to the beginning of the 18th century
However, science only put an end to the uncanny power of the Great Plague, and eased the fear and anxiety of human beings facing unknown threats
.
The origin of some ancient plagues is still difficult to determine today.
A typical example is AIDS
.
In 1980, a new disease, AIDS , was discovered in the United States .
AIDS AIDS
However, another HIV-positive blood sample was found in 1986 from a Danish doctor who died in 1977 and worked in Africa, which proves that the source should be in earlier Africa
.
At this time, zoologists also discovered that the laboratory monkeys had a virus similar to HIV, SIV
In 1998, scientists discovered two HIV blood samples from Africa around 1960, and estimated that their common ancestor could be traced back to around 1908
.
As scientists get samples of chimpanzee populations of African rain forest, heavy paper published in 2006: AIDS drug source, it is chimpanzee southeast Cameroon
AIDS
At this time, the HIV transmission chain reached a preliminary conclusion: SIV has existed in apes for millions of years
.
Hundreds of years ago, two SIVs were mixed on chimpanzees to form the predecessor of HIV
Once it is disturbed by politics, it is difficult to trace the virus to the source as smoothly as scientists study AIDS
.
From 1918 to 1920, the unknown flu virus swept the world, killing 50 million to 100 million people.
The media used to call it the "Spanish flu"
.
Later research found, might be called the "Great American flu" - authoritative organizations generally believe that the epidemic originated in March 1918 barracks, Kansas, is to participate in the First World War soldiers spread to the Europeans
.
At that time, science had defeated anthrax and smallpox.
People believed that science was omnipotent.
However, due to a series of complex factors brought about by the war, people knew no more about the 1918 flu than the people in the Middle Ages knew about the Black Death
.
It was not until 1933 that British scientists isolated the 1918 influenza virus from humans for the first time and named it "H1N1"; in 1997, American scientists believed that the 1918 influenza virus was very similar to the "swine flu virus" and was a kind of Type A (type A) influenza virus (H1N1) closely related virus; in 1998, the molecular pathology department under the US Defense Pathology Center (AFIP) obtained the Some genetic material of the influenza virus in 1918.
.
.
Although science helped us to understand the influenza virus in 1918, it is still difficult to trace the source.
There is no solid scientific evidence pointing to the source of the virus
.
It is only certain that the "Spanish flu" must not come from Spain
.
Due to the concealment of various countries-in 1918, when the deadly flu was first spread in the United States, the media feared that it would affect the morale of the people in the First World War and threatened everyone not to "warranty"
.
Britain and France have also been silent on the rapidly spreading infectious disease
.
Spain, as a neutral country, has no news control.
They carefully count the number of infections and deaths, and even the infection of King Alfonso XIII has been reported publicly
.
The foreign media stationed in Madrid immediately named the plague "Spanish flu"
.
In this way, Spain, the country that is most responsible for the epidemic, became the man behind the scenes; American politicians succeeded in diverting the anger of the people so that they would not be overwhelmed
.
But more than a century has passed, and the mystery of the origin of the 1918 flu is unknown
.
The traceability of viruses has always been dependent on scientists
.
It is difficult to trace the source, difficult for scientists, and even harder for troublemakers
.
History is always surprisingly similar.
At this time, the United States allows its intelligence agencies to trace the source.
Is there a lot of information?
