We examined the capacity of SARS-CoV-2 to infect and replicate in several common primate and human cell lines, including human adenocarcinoma cells (A549) [lung celles], human liver cells (HUH7.0), and human embryonic kidney cells (HEK-293T), in addition to Vero E6 and Vero CCL81 [monkey cells]…No cytopathic effect was observed in any of the cell lines except in Vero cells [monkey cells]…HUH7.0 and 293T cells showed only modest viral replication and A549 cells [human lung tissue cells] were incompatible with SARS-CoV-2 infection.”
The CDC did not observe any CPE in human cells. They saw no evidence that this alleged virus caused any human illness. Nor did this supposed human virus show any notable replication in human cells, suggesting human to human infection would be impossible.
