WASHINGTON — A U.S. intelligence report identified three researchers at a Wuhan lab who sought treatment at a hospital after falling ill in November 2019, a source familiar with the matter tells NBC News.
The new details, first reported by The Wall Street Journal, add to the body of circumstantial evidence that supports a hypothesis that the Covid-19 virus may have spread to humans after it escaped from a Chinese research lab in Wuhan. But the evidence is far from conclusive.
This reporting adds a new level of detail to the information put out in a Department of State fact sheet last year, which said the United States had confirmed that researchers at the Wuhan Institute of Virology had fallen ill.
