CRP and avian influenza: Moreover, CRP was noted as a predictor for worse outcomes in H1N1 infection and other related avian influenzas, but other data have shown that values > 100 mg/L may predict bacterial superinfection in influenza (pneumococci had the highest CRP values, alfa-hemolytic streptococci had the lowest CRP values), and generally, such elevated values can possibly predict bacterial infections in cases with influenza-like symptomatology [915,916,917,918].
