Preprint: COVID-19 Shows ‘Fingerprint’ of Laboratory Engineering

COVID-19’s genome shows signs consistent with genetic manipulation, according to a new preprint.

The preprint, released last week, argues that SARS-CoV-2, the virus that causes COVID-19, may have originated as a synthetic virus in the lab. It has not yet been peer reviewed or published in a scientific journal.

Like much of U.S. Right to Know’s work, the preprint examines available evidence in order to get a glimpse into what virology experiments might have been undertaken before the pandemic.

Two competing theories about the origin of COVID-19 have taken center stage. One theory holds that the virus spilled over from live mammals sold at a seafood market, while the other posits that the virus was released from a laboratory famous for collecting and studying coronaviruses.

To determine whether SARS-CoV-2 had characteristics of genetic manipulation, the authors looked at the pattern of markers called restriction sites in the SARS-CoV-2 genome. Restriction sites are locations where DNA is cut during genetic engineering.
