Viremia correlates with the main laboratory prognosis biomarkers described in patients hospitalized with severe COVID-19. Correlation between viremia levels (Ct value by Thermo Fisher Scientific [TFS] technique) and IL-6 levels (pg/mL) (A), lymphocytes count (cel/mm3) (B), LDH levels (U/L) (C), ferritin levels (ng/mL) (D), d-Dimer levels (mg/mL) (E). Data are shown as dot plots of the corresponding values and the fitted linear prediction (black line) obtained with the option lfit of the command twoway of Stata. Correlation coefficients and significance levels were estimated with the Pearson’s test.
