To the Editor: Influenza causes around 8% of community-acquired pneumonia (CAP) episodes,1 and during the (H1N1) 2009 influenza pandemic, concurrent bacterial infections were detected in up to 29% of fatal infections.2 Determining microbial aetiology of CAP can guide antibiotic and antiviral therapy.
