SARS-CoV-2 dose not linked with COVID-19 severity, review saysSARS-CoV-2 dose may affect infection rates, but current data do not show an association between viral dose and COVID-19 severity, according to a review of more than 100 SARS-CoV-2 studies that looks at COVID-19 infectious dose, viral load, severity, and variants.The aggregated findings were included in Clinical Infectious Diseases late last week and written by US researchers, led by scientists with the University of Minnesota's Center for Infectious Disease Research and Policy, publisher of CIDRAP News.An infectious dose, the researchers summarized, is often expressed as either the smallest quantity of virus that leads to infection or the median infectious dose.
