Chinanews.com, Beijing, July 8 (Jiang Li) The new crown pneumonia epidemic is spreading worldwide.

Up to now, many countries have successively discovered the new coronavirus in blood, throat swabs, biopsy, sewage and other samples, and it is earlier than the earliest known transmission time in the country.

　　U.S. researchers published the latest research report in the national "Clinical Infectious Diseases" magazine on June 15, and tested 24,079 blood samples collected from 50 states across the United States from January 2 to March 18, 2020. And analysis.

It was found that 9 samples were positive for antibodies, of which 7 were cases from 5 states including Illinois, earlier than the time of the first confirmed case officially announced by these 5 states.

This indicates that the new crown virus has appeared in the United States in December 2019.

　　Coincidentally, the University of California, Los Angeles has previously issued a report that the new crown virus may have existed in the Los Angeles area as early as December 2019.

　　In addition to the United States, Japan found antibodies to the new coronavirus from blood samples in early 2019. Italy and France detected the new coronavirus in biopsy samples and throat swab samples collected in December 2019.

Researchers from Spain, Brazil and other countries also found traces of the new coronavirus in the wastewater samples before the earliest confirmed cases were reported locally.

These discoveries continue to rewrite the timeline of the spread of the new coronavirus.

　　Scientists and researchers from many countries are trying their best to find the time point of the spread of the new crown virus and trace the origin of the epidemic in order to break this global pandemic as soon as possible.

However, some US politicians and media with ulterior motives have always targeted China on the issue of virus traceability.

They ignored the results of the WHO investigation, did not mention a word about the source of the virus in their country, and carried out political repression and personal attacks on some scientists who opposed the "Wuhan laboratory leak" conspiracy theory.

　　The reason is that the United States is anxious about China's development and is deeply afraid of threatening its world hegemony.

They need to find all kinds of excuses to slander and suppress China and put China on the cusp of international public opinion. This is also a tactic they have always used.

I advise the United States and the West not to try to use virus traceability as a "political tool" to curb China's development, but to use objective and fair scientific and technological means to study the origin of the new coronavirus in order to "defeat" the new coronavirus as soon as possible.

COVID-19 origin-tracing'political tool' used against China

By John Lee

(ECNS) – The COVID-19 pandemic is spreading widely around the world. To date, the coronavirus has been found in blood, throat swabs, biopsies, sewage and other samples in various countries, often earlier than the earliest known transmission time.

A study published in the Clinical Infectious Diseases journal on June 15 found that people in five US states were infected with the virus in December 2019. US researchers said that there was evidence of infection in nine out of 24,079 people whose blood samples were taken between Jan . 2, 2020, and March 18. The samples that tested positive for the virus came from Illinois, Massachusetts, Mississippi, Pennsylvania, and Wisconsin. This indicates that the COVID-19 had appeared in the US in December 2019.

It coincides with a previous report issued by UCLA that stated the coronavirus may have existed in the Los Angeles area as early as December 2019.

In addition to the US, COVID-19 antibodies were detected in blood samples tested in Japan in early 2019. The coronavirus was also found in biopsy samples collected in Italy and in throat swab samples from France, both in December 2019. Researchers from Spain and Brazil also found traces of the virus in wastewater samples before the earliest confirmed cases were reported locally. These discoveries are constantly rewriting the timeline of the emergence of the coronavirus.

Scientists from many countries are trying their best to determine the origin of COVID-19 and its earliest transmission. However, some US politicians and media have overtly targeted China regarding COVID-19 tracing. They purposefully ignore WHO investigation reports, remain mute on origin- tracing in their own country, and conduct political crackdowns and personal attacks on scientists who oppose the "lab-leak" conspiracy theory.

The reasons? The US is anxious about China's growth and fears that it may threaten its world dominance. They have to find excuses to slander and suppress China, and put China on the spot. The US is good at playing these tricks. The US should stop using COVID-19 origin-tracing as a "political tool" to restrain the development of China. Instead, it should research the origin through objective and impartial scientific means, so as to beat the pandemic.
