Nearly a month before community spread was first detected, “sustained, community transmission” of the coronavirus in the United States began in late January or early February, a report from the CDC says.
A “single importation” from China was followed by “several importations” from Europe, the study’s authors found.
“As America begins to reopen, looking back at how COVID-19 made its way to the United States will contribute to a better understanding to prepare for the future,” said CDC Director Robert Redfield.
Redfield said that the virus circulated at such low levels after being introduced in the US that earlier diagnostic tests would’ve missed it.
