Research by the Centers for Disease Control and Prevention: New Coronavirus may already exist in the United States in December last year

  Washington, December 3 (Reporter Zhang Mengxu) Researchers from the Centers for Disease Control and Prevention of the United States have recently discovered that antibodies to the new coronavirus were present in some blood samples donated by Americans in December last year, which means that the new coronavirus may have been in the United States at that time. It appeared earlier than the time when the first confirmed case of new coronary pneumonia was reported by the US official.

  The study, published on November 30 in the US "Clinical Infectious Diseases" bimonthly magazine, stated that in order to determine whether there were antibodies to the new coronavirus before the first confirmed case of new coronary pneumonia in the United States, researchers from the US Centers for Disease Control and Prevention tested the American Red Cross. 7,389 blood samples will be collected from December 13 last year to January 17 this year.

The samples came from blood donors in 9 states across the United States.

Test results found that 106 of the blood samples contained antibodies to the new coronavirus.

  The US Centers for Disease Control and Prevention reported the country's first confirmed case of new coronary pneumonia on January 21 this year.

According to the study, test results show that there may have been individual cases of new coronavirus infection in some parts of the United States in December last year, and another possibility is that a small part of the population has antibodies that can bind to the new coronavirus before.

  Previous studies in the United States also stated that the new coronavirus may have spread in Los Angeles before the first confirmed case of new coronary pneumonia was officially reported by the United States.
