武汉新冠瘟疫是针对中国的生物战争。投毒的一方实验室合成了针对黄种人的新冠病毒，这种病毒对黄种人的致死率比对白人高6到7倍左右，因此投毒者认为，即使瘟疫失控，对白人国家最多只是大号流感，事实证明投毒者的判断是正确的，现在死亡率只有1%。最初投毒者没想到病毒变异速度如此之快，开始时变异后的病毒对白人也有比较高的致死率; 投毒者也没有预料到中国人民能够全民一心，迅速打赢了这场灭亡中国的生物战争。中国政府当然不能宣布这是投毒，宣布投毒会使国民迫使政府对外宣战，中国还没有准备好。一开始很多人不相信我的判断，认为病毒来自中国的蝙蝠和穿山甲。现在你还这么认为吗？该醒醒啦。 6park.com
Covid-19 Likely in U.S. in Mid-December 2019, CDC Scientists Report

The new coronavirus infected people in the U.S. in mid-December 2019, a few weeks before it was officially identified in China and about a month earlier than public health authorities found the first U.S. case, according to a government study published Monday.
The findings significantly strengthen evidence suggesting the virus was spreading around the world well before public health authorities and researchers became aware, upending initial thinking about how early and quickly it emerged. 6park.com
Scientists at the U.S. Centers for Disease Control and Prevention found evidence of infection in 106 of 7,389 blood donations collected by the American Red Cross from residents in nine states across the U.S., according to the study published online in the journal Clinical Infectious Diseases. 6park.com
The scientists based their study on blood samples that the American Red Cross collected between Dec. 13 and Jan. 17 and later sent to the CDC for testing to see if any had antibodies to the new coronavirus, which is named SARS-CoV-2.
“SARS-CoV-2 infections may have been present in the U.S. in December 2019, earlier than previously recognized,” the authors wrote.

A person’s immune system develops antibodies when exposed to a pathogen like a virus to fight it off. Their presence suggests exposure to a virus.
In analyzing the blood samples, the CDC scientists found antibodies in 39 samples from California, Oregon and Washington state collected between December 13 and December 16.
The findings suggest there were isolated cases of coronavirus infection on the U.S. West Coast in mid-December, the scientists wrote.
They also found 67 samples with antibodies in Massachusetts, Michigan, Wisconsin or Iowa, and Connecticut or Rhode Island collected between Dec. 30 and Jan. 17.

Health experts say having a vaccine is just one front in a two-front battle against Covid-19. The other is effective treatments for those who are already sick with the disease.

The scientists said they ruled out the possibility that the antibodies they found had developed to fight off other coronaviruses, which cause the common cold. They did that by looking for antibodies specific to the new coronavirus in 90 of the samples.
They said they found antibodies specific to SARS-CoV-2 in 84 of the samples, or nearly all of them.
The results add to growing evidence suggesting Covid-19 was present outside of China earlier than previously known. Researchers found the virus, for example, in a retrospective analysis of a specimen from a patient who was hospitalized in France on Dec. 27, 2019.

The first Covid-19 case in the U.S. was reported on Jan. 19, two days after testing for the virus began there, the CDC researchers said. A young man returning from China a few days earlier suspected he might have the disease and sought care for his symptoms.
Two other people who were subsequently diagnosed in the U.S. also developed symptoms in mid-January.
Earlier studies have also suggested that Covid-19 had moved beyond just isolated cases and was spreading in communities in the U.S. by mid- to late-January, though epidemiologists say that the virus likely didn’t circulate widely in communities until later in February.
The new study shows the value of screening routinely collected blood samples for evidence of viruses spreading in a population, the CDC authors said, adding that the agency is continuing to conduct surveillance for Covid-19 this way.

Not only did Covid-19 likely appear in the U.S. earlier than previously known, but researchers have found evidence that the virus is far more widespread in the U.S. than testing indicates.
Some 53 million people in the U.S. likely had contracted Covid-19 by the end of September, according to a modeling estimate published last week by CDC researchers. Roughly 6.9 million infections had been confirmed within that time period, suggesting that roughly one in every eight cases was identified.
Yet the majority of the U.S. population hasn’t been infected. On Nov. 24, a CDC study published in the journal JAMA Internal Medicine estimated that fewer than 1% to 23% of people in the U.S. had antibodies, depending on the location.
