It now appears that COVID-19 was in the US as early as December 2019



COVID-19 may have arrived in the United States as early as December 2019, before the disease was even diagnosed in China, a new study suggests.

The researchers on the study, from the Centers for Disease Control and Prevention (CDC), analyzed more than 7,000 blood donations collected by the American Red Cross in nine states between December 13, 2019 and January 17, 2020.

Of these, 106 samples tested positive for antibodies to SARS-CoV-2, the virus that causes COVID-19.
