A/H1N1/2009, pandemic A (H1N1) 2009 influenza virus; CRP, blood C‐reactive protein; NS, not significant; RSV, respiratory syncytial virus; RV, rhinovirus; WBC, white blood cell; only hospitalized patients with single infections were considered.

^aAge‐adjusted severity score [6].

^bRSV vs. A/H1N1/2009: p <0.05, calculated with Fisher’s exact test.

^cRV vs. RSV: p <0.05, calculated with the Mann–Whitney U‐test.

^dRSV vs. A/H1N1/2009 and RSV vs. RV: p <0.05, calculated with the Mann–Whitney U‐test.

^eRV vs. RSV and RV vs. A/H1N1/2009: p <0.05, calculated with the Mann–Whitney U‐test.
