Research identifies missed COVID-19 cases by retrospective testing of throat swabs
Research published today in the
Journal of General Virology has identified missed cases of SARS-CoV-2 by retrospective testing of throat swabs.
Researchers at the University of Nottingham screened 1,660 routine diagnostic specimens which had been collected at a Nottingham hospital between 2 January and 11 March 2020 and tested for SARS-CoV-2 by PCR.

The Human Genome Project (HGP) had labored for a decade to read this coded information. In a White House press conference in 2000, Francis Collins, who led the project as director of the US National Human Genome Research Institute, waxed Biblical, calling the human genome “our own instruction book, previously known only to God.”
The HGP has huge potential benefits for medicine and our understanding of human diversity and origins, but a blizzard of
