According to the Wall Street Journal report, researchers from the U.S. Center for Disease Control and Prevention (CDC) found antibodies produced to defend against Kovid-19 in blood donations collected by the American Red Cross in 9 states on 13 December-17 January.
CDC researchers published their findings in the journal “Clinical Infectious Diseases”, “Covid-19 infections may have emerged in the United States in December 2019, before they were previously identified.” he used the expression.
The researchers examined 7,389 blood samples collected December 13-16 in Washington, Oregon and California in the western part of the country and in the eastern states of Massachusetts, Michigan, Wisconsin, Iowa, Connecticut and Rhode Island from December 30 to January 17.
Antibodies developed against Kovid-19 were found in the blood in 39 of the samples collected from the western states and in 67 of the samples collected from the eastern states.

Experts commented that the findings show that the Kovid-19 outbreak spread regionally in the country in December last year.
Since antibodies in the blood are an indirect sign of the presence of the virus in the body, it is not fully confirmed that a person with a positive antibody test has taken Kovid-19. According to the procedures of the World Health Organization (WHO), the nucleic acid-based polymerase chain reaction (PCR) that reproduces a specific genetic sequence in the virus must be detected in swab samples taken from the mouth and nose for the diagnosis of Kovid-19 infection.
The first case of Kovid-19 in the US was seen on January 19 in the city of Snohomish, in the western state of Washington, in a 35-year-old male patient who came to the health center with a fever and cough disorder for 4 days. It is understood that the patient returned to the United States on January 15 from Wuhan, China, where he went for a family visit.
In the United States, where the highest number of cases and deaths due to the virus have been recorded worldwide, 14 million 108 thousand 606 cases of Kovid-19 have been detected so far, 276 thousand 979 people have died from the virus.
