According to the report, a long-term project called "All of Us" by the National Institutes of Health (NIH) aims to track the health of 1 million volunteers. The study requires blood donations from volunteers.
The latest report published in the Journal of Clinical Infectious Diseases of the American Society of Infectious Diseases stated that researchers analyzed more than 24,000 blood samples collected in the first three months of 2020, and at least nine people had antibodies to the new coronavirus in their blood.
These frozen blood samples indicate that people were infected with the new crown virus a few days or weeks before the official report of the new crown virus case in Illinois, Wisconsin, Pennsylvania, Mississippi and Massachusetts.
According to the report, blood samples were collected in Illinois, Massachusetts, Wisconsin, Pennsylvania, and Mississippi on January 7, January 8, February 3, February 15, and March 6, respectively.
The five states reported the first confirmed cases of new crowns on January 24, February 1, February 5, March 6, and March 11.
The researchers said that because it takes about two weeks to produce antibodies after infection, the results of the study show that as early as December 2019, there have been cases of new crown infection in the United States.
According to data from Johns Hopkins University, as of 6:22 on June 16, Beijing time, the new crown epidemic has infected 33,483,919 people in the United States and more than 600,000 deaths.
