Kathleen Hall Jamieson of the Annenberg Public Policy Center said public health disinformation from China-based social media accounts is nothing new. "Early in the pandemic, Chinese sources spread the theory that SARS CoV-2 originated at Fort Detrick and was spread to China by U.S. military," she said. "The platforms can remove it, or if they decide against doing so, can downgrade it or flag it and attach fact-checking content."
