But influenza associated aspergillosis cases mostly accompanied with more H1N1 subtype (91.7 vs. 79.8%, P = 0.037) and higher level of C-reactive protein (CRP) (117.6 ± 88.1 vs. 78.5 ± 75.2, P = 0.017) and interleukin 6 (IL-6) (133.5 ± 149.2 vs. 69.9 ± 100.0, P = 0.021) than those without aspergillosis. Here, CRP is linked to aspergillosis.
