Background. The current study aims to describe the demographical and clinical characteristics of elderly nursing home (NH)\nresidents with acute respiratory infections (ARIs) during four winter seasons (2013/2014ââ?¬â??2016/2017), as well as the microbiological\netiology of these infections. Methods. Seventeen NHs with at least one ARI resident in Corsica, France, were included. An ARI\nresident was defined as a resident developing a sudden onset of any constitutional symptoms in addition to any respiratory signs.\nNasopharyngeal swabs from ARI residents were screened for the presence of 21 respiratory agents, including seasonal influenza\nviruses. Results. Of the 107 ARI residents enrolled from NHs, 61 (57%) were positive for at least one of the 21 respiratory pathogens.\nForty-one (38.3%) of the 107 ARI residents had influenza: 38 (92%) were positive for influenza A (100% A(H3N2)) and three (8%)\nfor influenza B/Victoria. Axillary fever (ââ?°Â¥38âË?Ë?C) was significantly more common among patients infected with influenza A(H3N2).\nConclusion.The circulation of seasonal respiratory viruses other than influenza A(H3N2) seems to be sporadic among elderly NH\nresidents. Investigating the circulation of respiratory viruses in nonwinter seasons seems to be important in order to understand\nbetter the dynamic of their year-round circulation in NHs.
