Molecular techniques increased the number of documented respiratory infections. In a substantial number of cases the causative agent remains undetected. Since August 2014, an increase in Enterovirus(EV)-D68 infections was reported. We aimed to investigate epidemiology and clinical relevance of EV-D68. From June to December 2014 and from September to December 2015, 803 and 847 respiratory specimens, respectively, were tested for respiratory viruses with a multiplex RT-PCR. This multiplex RT-PCR does not detect EV-D68. Therefore, 457 (2014) and 343 (2015) specimens with negative results were submitted to an EV-specific-RT-PCR. EV-positive specimens were tested with an EV-D68-specific-RT-PCR and genotyped. Eleven specimens of 2014 tested positive in the EV-specific-RT-PCR and of these seven were positive in the EV-D68-specific-RT-PCR. Typing confirmed these as EV-D68. Median age of EV-D68-positive patients was 3 years (1 month-91 years). Common symptoms included fever (n = 6, 86%), respiratory distress (n = 5, 71%), and cough (n = 4, 57%). All EV-D68-positive patients were admitted to hospital, 4 (57%) were admitted to intensive care units and 6 (86%) received oxygen. One patient suffered from acute flaccid paralysis. Seven specimens of 2015 were positive in the EV-specific-RT-PCR but negative in the EV-D68-specific-RT-PCR. In conclusion, use of an EV-specific-RT-PCR allowed us to detect EV-D68 circulation in autumn 2014 that was not detected by the multiplex RT-PCR and was associated with severe disease.
