US CDC: Early novel coronavirus cases found in the United States
According to the Wall Street Journal of the United States, a government study released by US CDC scientists on November 30 showed that as early as mid-December 2019, the novel coronavirus appeared in the United States, which is earlier than the official discovery of the novel coronavirus in China. A few weeks, one month before the first confirmed case in the United States was discovered by the US public health department.
A study published in the journal Clinical Infectious Diseases by scientists of the Centers for Disease Control and Prevention showed that 106 of the 7,389 blood samples collected by the American Red Cross from residents of 9 states in the United States Evidence of infection with the new coronavirus was found. These blood samples were collected by the Red Cross from December 13, 2019 to January 17, 2020, and sent to the Centers for Disease Control and Prevention for testing to see if there are antibodies against the new coronavirus. During the analysis, the scientists found antibodies to the new coronavirus in 39 samples collected from California, Oregon, and Washington from December 13 to December 16.

The author wrote: “New coronavirus infection may have appeared in the United States in December 2019, which is earlier than our previous understanding.” The article also pointed out that these findings indicate that there were isolated cases of new coronavirus infection on the west coast of the United States in mid-December. . In addition, from December 30 to January 17, 2020, scientists found 67 blood samples with COVID-19 antibodies in Massachusetts, Michigan and other places.
The Wall Street Journal pointed out in the article that the results of this study also show that there is more and more evidence that the new crown virus appeared outside of China earlier than previously known times. For example, when researchers retrospectively analyzed samples of French hospitalized patients on December 27, 2019, they also discovered this virus. Research reflects that the new coronavirus may not only appear in the United States earlier than previously known, but researchers have also found evidence that the spread of the virus in the United States is much more widespread than test results indicate.
