Distribution of viruses and the most frequently isolated microorganism in the study population The influenza A subtypes included 4 H3N2, 3 (H1N1)pdm09, and 2 untyped strains. *Coagulase‐negative staphylococci **M. catharrhalis, S. marcescens, E. cloacae, K. oxytoca, P. vulgaris, P. acnes, Pseudomonas‐ species, Micrococcus‐species, Bacillus‐species ***C. dubliniensis, C. koseri, C. glabrata, C. tropicalis, C. krusei, unspecified Candida‐species A total of 122 patients were tested for viruses, including parainfluenza viruses 1–3. Nineteen were virus‐positive. Co‐infections with clinically significant microbiological pathogens were found in four virus‐positive patients. Of the virus‐negative patients, 67 were positive for either bacteria or fungi, and two patients were not tested. Thirty‐four were negative for bacteria/fungi. Agents of considered relevance for the respiratory symptoms were isolated in 23 of the 67 patients; seven from blood and 21 from tracheal aspiration.
