科学家说检测结果非常可靠,一共检测了24000份美国人血样。而且在美国多个地点检

More evidence suggests COVID-19 was in US by Christmas 2019

China tells NATO to stop 'hyping up' threat after alliance singles it out
'Diamond rush' grips South African village after discovery of unidentified…

NEW YORK (AP) — A new analysis of blood samples from 24,000 Americans taken
early last year is the latest and largest study to suggest that the new
coronavirus popped up in the U.S. in December 2019 — weeks before cases
were first recognized by health officials.

The analysis is not definitive, and some experts remain skeptical, but
federal health officials are increasingly accepting a timeline in which
small numbers of COVID-19 infections may have occurred in the U.S. before
the world ever became aware of a dangerous new virus erupting in China.


“The studies are pretty consistent,” said Natalie Thornburg of the Centers
for Disease Control and Prevention.

“There was probably very rare and sporadic cases here earlier than we were
aware of. But it was not widespread and didn't become widespread until late
February," said Thornburg, principal investigator of the CDC's respiratory
virus immunology team.

The pandemic coronavirus emerged in Wuhan, China in late 2019. Officially,
the first U.S. infection to be identified was a traveler — a Washington
state man who returned from Wuhan on Jan. 15 and sought help at a clinic on
Jan. 19.

CDC officials initially said the spark that started the U.S. outbreak
arrived during a three-week window from mid-January to early February. But
research since then — including some done by the CDC — has suggested a
small number of infections occurred earlier.

A CDC-led study published in December 2020 that analyzed 7,000 samples from
American Red Cross blood donations suggested the virus infected some
Americans as early as the middle of December 2019.

Gallery: 40 Things Your Doctor Wishes You Knew About Vaccines (The Healthy)

a person taking a selfie: Efforts to develop a vaccine for Covid-19 are
happening at warp speed, says Kathyrn M. Edwards, MD, a spokesperson for the
Infectious Diseases Society of America (IDSA). There are currently more
than 100 vaccine candidates in some stage of development, eight of them
already in clinical trials. There are still a lot of questions about
potential vaccines, such as when they will be released (if we’re supremely
lucky maybe later in 2020, or even in a year or more) or even if antibodies
that are normally what make vaccines effective will be protective against
this new virus and for how long, says Richard Kuhn, PhD, The Trent and
Judith Anderson Distinguished Professor in Science at Purdue University.
While we’re waiting for those answers, don’t forget that there are dozens
of effective vaccines for other diseases already out there. And for those,
we do have a lot of answers.
The latest study, published Tuesday online by the journal Clinical
Infectious Diseases, is by a team including researchers at the National
Institutes of Health. They analyzed blood samples from more than 24,000
people across the country, collected in the first three months of 2020 as
part of a long-term study called “All Of Us” that seeks to track 1 million
Americans over years to study health.

Like the CDC study, these researchers looked for antibodies in the blood
that are taken as evidence of coronavirus infection, and can be detected as
early as two weeks after a person is first infected.

The researchers say nine study participants — five from Illinois, and one
each from Massachusetts, Mississippi, Pennsylvania, and Wisconsin — were
infected earlier than any COVID-19 case was ever reported in those states.

One of the Illinois cases was infected as early as Christmas Eve, said Keri
Althoff, an associate professor at the Johns Hopkins Bloomberg School of
Public Health and the study's lead author.

It can be difficult to distinguish antibodies that neutralize SARS-CoV-2,
the virus that causes COVID-19, from antibodies that fight other
coronaviruses, including some that cause the common cold. Researchers in
both the NIH and CDC studies used multiple types of tests to minimize false
positive results, but some experts say it still is possible their 2019
positives were infections by other coronaviruses and not the pandemic strain.

“While it is entirely plausible that the virus was introduced into the
United States much earlier than is usually appreciated, it does not mean
that this is necessarily strong enough evidence to change how we're thinking
about this," said William Hanage, a Harvard University expert on disease
dynamics.

The NIH researchers have not followed up with study participants yet to see
if any had traveled out of the U.S. prior to their infection. But they found
it noteworthy that the nine did not live in or near New York City or
Seattle, where the first wave of U.S. cases were concentrated.

“The question is how did, and where did, the virus take seed,” Althoff
said. The new study indicates “it probably seeded in multiple places in our
country,” she added.

这种研究没有意思,应该找2019年的血样。CDC使用的血样最早是2019年12月13日,应
该继续往前追
collected in the first three months of 2020

中国持有军运会几千名参与者的血样,显然也持有武汉市2019年的血样。就等美帝什么

可以把2019年全年都测一遍,看看抗体出现的高峰是否符合各种关于新冠的理论。
比如,如果全年平均分布,或者年初有个高峰,那么就可能是其它原因引起的抗体。
