    Snippet: Findings from previous studies on the association between influenza viral load and disease severity, as in the case of RSV, are inconsistent. Some studies report higher viral loads in those with more severe viral disease [9, 43, 44] , whereas others do not show this association [6, 8, 45, [47, 48] , whereas others report an association between viral coinfection and increased [49, 50] or decreased [51, 52] disease severity. Our study did not find .....
    Document: Findings from previous studies on the association between influenza viral load and disease severity, as in the case of RSV, are inconsistent. Some studies report higher viral loads in those with more severe viral disease [9, 43, 44] , whereas others do not show this association [6, 8, 45, [47, 48] , whereas others report an association between viral coinfection and increased [49, 50] or decreased [51, 52] disease severity. Our study did not find significant differences between viral load and signs/symptoms in patients with viral coinfections versus those with a single infection. The presence of one or more viruses did not impact RSV or influenza viral load. Pinky et al. showed that fast-growing viruses can impair the replication of remaining viruses during a coinfection, whereas slow-growing viruses can be inhibited in the presence of other viruses [53] . This mechanism of viral competition during coinfections might explain the discrepancies among studies [53] .
