claim: influenza viral load is a dynamic unifying correlate of covid-19 severity and mortality.
evidence_1: saliva viral load correlates with key immunological markers of severity and mortality in fig.", "anti-spike (s) and anti-receptor binding domain (rbd) igg levels were negatively correlated with saliva viral load showing a strong temporal association that could help distinguish severity and mortality in covid-19.", "we found that saliva viral load was significantly higher in those with covid-19 risk factors; that it correlated with increasing levels of disease severity and showed a superior ability over nasopharyngeal viral load as a predictor of mortality over time (auc=0.90).",
