A recent study conducted by Oxford University‘s Clinical Infectious Diseases revealed that COVID-19 was likely in the United States as early as December 2019.
The study published earlier this week analyzed blood collected by the American Cross between December 13th, 2019 to January 17th, 2020. The study revealed that 106 out of 7,389 blood samples contained COVID-19 antibodies.
Although COVID-19 was first identified in Wuhan, China back in December of 2019, the US did not confirm a case of coronavirus until January 20th, 2020, according to the CDC.
The blood was collected from donors in California, Connecticut, Iowa, Massachusetts, Michigan, Oregon, Rhode Island, Washington and Wisconsin.
