DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Research highlights challenges in utilizing Ct data to guide COVID-19 clinical planning

In a new study, a collaboration of researchers from various institutes described the natural history of SARS-CoV-2 testing, which includes Ct values among patients who had tested positive multiple times, prior to the emergence of VOCs in the vaccine roll-out. In addition, the authors analyze the timescale of positivity and clinical features of the population of patients with prolonged SARS-CoV-2 positivity.
