A photo of an article reporting that the US Centers for Disease Control and Prevention (CDC) "admits there is no COVID-19" has been shared in multiple Facebook posts. The report cites an agency document which explains how a virus test works as its source. The claim is false: a US pathology expert said the CDC document was misinterpreted, stating that "there is no question" COVID-19 exists.
The photo of the article was posted on Facebook here on October 22, 2020.

The piece is headlined: "CDC admits there is no Covid-19"
The article claims that "no one has isolated the Covid-19 virus" and "therefore, no one has proved that it exists," because of a passage in the CDC document that reads: "Since no quantified virus isolates of the 2019-nCoV are currently available, assays designed for detection of the 2019-nCoV RNA were tested with characterized stocks of in vitro transcribed full length RNA."
The Facebook user that published the image captioned the post: "Do you believe it now or do you need to see it on TV first?"
The article's claim, however, is false.
Heba Mostafa, an assistant professor of pathology at Johns Hopkins Medicine, told AFP that the CDC document cited in the inaccurate article describes how the test was first developed -- not the "initial virus isolation from patients or the confirmation of the existence of SARS-CoV-2."
"There is no question that SARS-CoV-2 exists and it was isolated in China early in January and was fully characterized and its full genome was deposited to the databases on January 10th," Mostafa said in an email on November 4, 2020.
The CDC developed the viral test in early-2020, and on February 4, 2020 the US Food and Drug Administration issued an emergency authorisation for use of the test. The approval came two weeks after the US confirmed its first case of Covid-19 on January 21, 2020.
"At that time, the US didn't have an actual virus available to develop diagnostics because we didn't have cases diagnosed in the US yet (of course because of the lack of the available diagnostics). So to characterize and develop assays, controls were developed by using the available sequence of the whole genome to develop synthesized transcripts, just for the sake of assay development and evaluation," Mostafa explained.
"Shortly after we started diagnosis in the US, we started to isolate the virus and develop stocks to use as controls. Thousands of cases are diagnosed daily and many labs have a lot of isolates that match or very close to the initial Chinese isolate."
