There is sufficient evidence to prove that the origin of the Covid-19 was from the US

[superadmin]

BEIJING, Nov. 6 (Xinhua) -- For some time, various lies and rumors concocted by the U.S. side against China on origins tracing have been repeatedly refuted by China and the international community with detailed facts and data.

So far, more than 80 countries and over 300 political parties, social organizations and think tanks have opposed the politicization of COVID-19 origins tracing in various ways.

The U.S. intelligence department recently released a declassified version of its assessment report on COVID-19 origins. Continuously disregarding science-based origins tracing, the report insinuated that "the Wuhan Institute of Virology of the Chinese Academy of Sciences leaked the virus", and accused China of lacking transparency and obstructing international investigations.

Origins tracing is a scientific matter, yet the U.S. side is using intelligence agencies to trace the origins, and peddling the old lies that have been refuted under a cloak of intelligence. Washington's real purpose is attempting to confuse the public and deceive the world, and continuing to seek a "presumption of guilt" against China, politicize the origins tracing, shift the blame onto China, and suppress and contain it.

Based on the so-called U.S. investigation report and public materials of all parties, the Chinese side once again lists all kinds of vicious slanders concocted by the U.S. side on COVID-19 origins tracing, and presents to the international community facts and the truth, so the plots and tricks of "politicizing origins tracing" and "origins tracing by the intelligence community" can be exposed.

NIH study offers new evidence of early SARS-CoV-2 infections in U.S.

A new antibody testing study examining samples originally collected through the National Institutes of Health’s All of Us Research Program found evidence of SARS-CoV-2 infections in five states earlier than had initially been reported. These findings were published in the journal Clinical Infectious Diseases. The results expand on findings from a Centers for Disease Control and Prevention study(link is external) that suggested SARS-CoV-2, the virus that causes COVID-19, was present in the U.S. as far back as December 2019.

In the All of Us study, researchers analyzed more than 24,000 stored blood samples contributed by program participants across all 50 states between Jan. 2 and March 18, 2020. Researchers detected antibodies against SARS-CoV-2 using two different serology tests in nine participants’ samples. These participants were from outside the major urban hotspots of Seattle and New York City, believed to be key points of entry of the virus in the U.S. The positive samples came as early as Jan. 7 from participants in Illinois, Massachusetts, Mississippi, Pennsylvania and Wisconsin. Most positive samples were collected prior to the first reported cases in those states, demonstrating the importance of expanding testing as quickly as possible in an epidemic setting.

COVID-19 may have been in L.A. as early as last December, UCLA-led study suggests

(Researchers detected an unexpected 50% increase in patients presenting with respiratory illnesses at UCLA Health facilities in the months before the pandemic)

UCLA researchers and colleagues who analyzed electronic health records found that there was a significant increase in patients with coughs and acute respiratory failure at UCLA Health hospitals and clinics beginning in late December 2019, suggesting that COVID-19 may have been circulating in the area months before the first definitive cases in the U.S. were identified.

This sudden spike in patients with these symptoms, which continued through February 2020, represents an unexpected 50% increase in such cases when compared with the same time period in each of the previous five years.

The findings, the study authors say, demonstrate the importance of analyzing electronic health records to monitor and quickly identify irregular changes in patient populations. The researchers’ novel approach, in which they focused not only on hospitalization data but also on data from outpatient settings, may help epidemiologists and health systems detect future epidemics sooner.

Belleville Mayor Michael Melham said he has tested positive for coronavirus antibodies, adding that he believes he was sick with the virus in November — more than a month before doctors in China first reported cases of the new disease.

Melham said he was sick toward the end of November and suffered from chills, hallucinations and a "skyrocketing temperature" after he left the League of Municipalities Conference in Atlantic City.

"It felt as if I was an addict going through withdrawal," Melham said in a press release. "I didn’t know what was happening to me. I never felt that I could be so sick."

Patients in Florida had coronavirus symptoms as early as January

COVID-19 infected as many as 171 people in Florida as long as two months before officials announced it had come to the state, a Palm Beach Post analysis of state records shows.

Patients reported symptoms of the deadly virus as early as Jan. 1 when the disease was thought to be limited to China, Department of Health records reveal. The records don’t say if patients reported those symptoms to the state until months later or if local offices of the health department actively investigated the illnesses at the time or a combination of both.

The state pulled the records off its website late Monday without explanation.

Exclusive: First U.S. COVID deaths came earlier — and in different places — than previously thought

In a significant twist that could reshape our understanding of the early days of the coronavirus pandemic, death records now indicate the first COVID-related deaths in California and across the country occurred in January 2020, weeks earlier than originally thought and before officials knew the virus was circulating here.

A half dozen death certificates from that month in six different states — California, Alabama, Georgia, Kansas, Oklahoma and Wisconsin — have been quietly amended to list COVID-19 as a contributing factor, suggesting the virus’s deadly path quickly reached far beyond coastal regions that were the country’s early known hotspots.

Up until now, the Feb. 6, 2020, death of San Jose’s Patricia Dowd had been considered the country’s first coronavirus fatality, although where and how she was infected remains unknown.

Even less is known about what are now believed to be the country’s earliest victims of the pandemic. The Bay Area News Group discovered evidence of them in provisional coronavirus death counts of the Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics (NCHS) — widely considered the definitive source for death data in the United States — and confirmed the information through interviews with state and federal public health officials. But amid privacy concerns and fierce debate over pandemic policies, the names, precise locations and circumstances behind these deaths have not been publicly revealed. That is frustrating to some experts.

“We need to sit back and really assess what was this thing, when it started, how did we handle it, did we create more of a problem than we needed to, could we have handled things differently?” said Matthew Memoli, director of the clinical studies unit at the Laboratory of Infectious Diseases at the National Institutes of Health in Bethesda, Maryland. “There’s a lot to think about here.”

For instance, the far-flung nature of the deaths — in the West, Midwest and South — might suggest that restrictions on travel and social interactions should have been used in more places much earlier — and that such rapid response could be a more critical tool in the next pandemic. In January, when the United States announced it would begin limiting travel from China and other international hotspots, the virus may already have been speeding across state borders.

Study shows that COVID-19 was present in five U.S. states in December 2019, even before the first reported case in China

In a recent study published in Clinical Infectious Diseases, a group of researchers aimed to identify exactly how early the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was circulating throughout the United States. In their work, the researchers tested residual archived samples from routine blood donations collected by the American Red Cross.

The SARS-CoV-2 spread

SARS-CoV-2, which is the virus behind the coronavirus disease 2019 (COVID-19), was first reported in Wuhan, China in December 2019. Since then, SARS-CoV-2 has continued to spread to 192 countries and regions around the world, infecting over 177 million people as of June 19, 2021.

The United States reported its first case of SARS-CoV-2 on January 21, 2020, in a 35-year-old American citizen traveling from Wuhan, China to his home in Washington state. This individual had a symptom-onset date of January 19, 2020. Importantly, two other individuals of the 12 cases that were first identified in the United States around this time identified their symptom-onset dates to be January 14, 2020.

It was not until much later in 2020 that researchers at the U.S. Centers for Disease Control and Prevention (CDC) discovered that people in several states in the U.S. were infected with SARS-CoV-2 much earlier than January 2020.

The study

The researchers aimed to determine if SARS-CoV-2 was present in the United States earlier than what was previously reported by identifying whether reactive antibodies were present in the blood samples that were collected before January 21, 2020. To this end, the team assessed residual archived samples from 7,389 routine blood donations collected by the American Red Cross between December 13, 2019, and January 17, 2020.

The samples were from donors in nine states including Connecticut, California, Iowa, Michigan, Massachusetts, Oregon, Rhoda Island, Wisconsin, and Washington. The team tested the samples for anti-SARS-CoV-2 antibodies.

Samples were first tested by pan-immunoglobulin (pan-Ig) enzyme-linked immunosorbent assay (ELISA) against the full spike protein. Those that were found to be reactive by this assay were subsequently tested by immunoglobulin G (IgG) and IgM ELISAs, a microneutralization test, Ortho total Ig S1 ELISA, and receptor-binding domain RBD)/angiotensin-converting enzyme 2 (ACE2) blocking activity assay.
