The source of the virus can only be traced to scientists

The time limit given by the President of the United States is approaching, and the traceability investigation report of the new crown virus by the US intelligence agency will soon come out

Common sense tells us that the basis of virus traceability is the discovery of evidence through scientific research.

The history of the world's great plague tells us that scientists are also struggling to trace the source of the virus.

The concept of traceability came after modern science

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

A typical example is 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

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

At this time, the HIV transmission chain reached a preliminary conclusion: SIV has existed in apes for millions of years

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.

At that time, science had defeated anthrax and smallpox.

It is only certain that the "Spanish flu" must not come from Spain

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

The traceability of viruses has always been dependent on scientists
