SARS-CoV-2 RNA detected in blood samples from patients with COVID-19 is not associated with infectious virus	2020-05-26		.txt	text/plain	4992	305	53	Background: Laboratory diagnosis of SARS-CoV-2 infection (the cause of COVID-19) uses PCR to detect viral RNA (vRNA) in respiratory samples. . https://doi.org/10.1101/2020.05.21.20105486 doi: medRxiv preprint prevalence of vRNA detection in blood, serum or plasma, noting whether this attribute was correlated with clinical or laboratory phenotypes of disease, and recording Ct values when these were reported. We collected 212 serum samples through the microbiology department at Oxford University Hospitals NHS Foundation Trust, OUH NHSFT, comprising adults with a diagnosis of COVID-19, confirmed by SARS-CoV-2 detection by a clinical diagnostic microbiology laboratory using RT-PCR on a respiratory swab, classified in three groups as follows: Based on a systematic review of the literature, together with our own data, we estimate that SARS-CoV-2 RNA may be present at low copy numbers in ~10% of blood samples obtained from individuals with COVID-19 prior to day 28, most of which arise at earlier timepoints and in the setting of more severe disease.	./cache/cord-346544-kk7qyn4w.txt	./txt/cord-346544-kk7qyn4w.txt
