In Germany, no surveillance data and no sequence information on circulating influenza C viruses have ever been reported. We furthermore sequenced the haemagglutinin esterase (HE) gene from influenza C-positive samples to phylogenetically characterise the detected viruses. To extend the basis for the co-infection data, all influenza C-positive samples were additionally tested for human parainfluenza viruses types 1-4 and coronaviruses OC43, NL63, HKU1 and 229E. Thereby, the low detection rates in the general population were confirmed, but a higher clinical impact for paediatric patients was indicated, as influenza C was described to also cause lower respiratory tract disease [6] [7] [8] [9] [10] .	./cache/cord-003523-byxuruk1.txt	./txt/cord-003523-byxuruk1.txt
