Coronavirus was present in US earlier than initially thought: Study
LOS ANGELES - Though the first case of the coronaviruswasn’t identified in the U.S. until January, a new study suggests that the novel disease was present earlier in the country than first thought.
A study published Monday in the journal Clinical Infectious Diseases conducted by researchers with the Centers for Disease Control and Prevention suggests that the novel virus was present in the United States as early as mid-December 2019.
The conclusion is based on blood donations from the Red Cross from nine states, including Washington, Oregon, California, Connecticut, Iowa, Massachusetts, Michigan, Rhode Island and Wisconsin.
More specifically, evidence of SARS-CoV-2, the scientific name for the novel virus, was present in 106 of the 7,389 blood donations, which were collected between Dec. 13, 2019, and Jan 17, 2020, according to the study.
Antibodies to the virus were found in 39 blood samples from Washington, Oregon and California, and they were found in 67 samples from the other six states.
“These findings suggest that SARS-CoV-2 may have been introduced into the United States prior to January 19, 2020,” the researchers stated. The findings also “highlight the value of blood donations as a source for conducting SARS-CoV-2 surveillance.”
Other studies have also suggested the virus may have been present in the U.S. earlier than first thought. Specifically, a study published in September conducted by researchers from the University of California, Los Angeles, and the University of Washington said that the novel virus may have been present last year in Los Angeles around Christmas.
Fox News’ Amy McGorry contributed to this report.

New York Gov. Andrew Cuomo on Thursday described the pandemic in the U.S. as a "virus of American division and federal incompetence."
Cuomo pointed to a recent report from the U.S. Centers for Disease Control and Prevention that he said proved the coronavirus came to New York predominantly from Europe and not China.
"By the time the president did the China travel ban, it was too late, because the virus had left China and went to Europe," Cuomo said.
