We conducted a systematic investigation of pneumococcal co-infection in patients with a diagnosis of pandemic (H1N1) 2009 and any risk factor for complications or with severity criteria. We found 14% prevalence, with one third of patients having nonpneumonic infections. A severity assessment score >1 and high C-reactive protein levels were predictors of pneumococcal co-infection.

Influenza virus and Streptococcus pneumoniae are 2 of the most frequently implicated pathogens in respiratory tract infections in humans. Although an interaction between these microorganisms has been suggested (1–8), few data are available addressing the prevalence, clinical spectrum, or predictive factors of pneumococcal co-infection for patients with influenza.

We investigated the prevalence and clinical characteristics of pneumococcal infection in patients infected with pandemic (H1N1) 2009 virus. We compared those patients with patients in whom only influenza or pneumococcal infection was diagnosed during the pandemic to identify potential predictors of co-infection.
