VIRAL DOSE AND DISEASE SEVERITY

Chad Roy, professor of microbiology and immunology and director of infectious disease aerobiology at the Tulane National Primate Research Center, and Dr. Gregory Bix, professor and vice chair of neurosurgery and neurology, director of COBALT (COVID-19 Biobank and Library at Tulane), and director of the clinical neuroscience research center, were among a team of scientists who co-authored a review of 115 peer-reviewed studies in Clinical Infectious Diseases. They concluded that the viral dose, or amount of the infectious virus SARS-CoV-2 transmitted from one person to another, does not appear to affect COVID-19 disease severity.
