“…In the literature, dual viral infection is found in 5-20% of infected patients (Huang et al, 1998;Weigl et al, 2000;Ong et al, 2001;Brandt et al, 1986;Aberle et al, 2005), while multiple viral infections with three or more agents are considered anecdotal (Jennings et al, 2004;Huang et al, 1998). These rates of coinfection are similar to those found in this series (17.4% of all positive samples), although the rate was higher when sensitive PCR techniques were used which allow for the detection of a larger number of viruses (Subbarao et al, 1989;Legg et al, 2005;Brouard et al, 2000).…”

“…A previous study of infants showed that co-infections of RSV and other viruses caused a higher incidence of fever and longer duration of hospitalization compared to solitary RSV infection [10]. However, in some studies, no clinical differences were reported [11, 12]. In this study, the number of cases was too small to compare the clinical outcomes.…”

BackgroundEtiologies and clinical profiles of acute respiratory viral infections need to be clarified to improve preventive and therapeutic strategies.Materials and MethodsA retrospective observational study at a single, university-affiliated center was performed to evaluate the respiratory viral infection etiologies in children compared to that in adults and to document the clinical features of common viral infections for adults from July 2009 to April 2012.ResultsThe common viruses detected from children (2,800 total patients) were human rhinovirus (hRV) (31.8%), adenovirus (AdV) (19.2%), respiratory syncytial virus (RSV) A (17.4%), RSV B (11.7%), and human metapneumovirus (hMPV) (9.8%). In comparison, influenza virus A (IFA) had the highest isolation rate (28.5%), followed by hRV (15.5%), influenza virus B (IFB) (15.0%), and hMPV (14.0%), in adults (763 total patients). Multiple viruses were detected in single specimens from 22.4% of children and 2.0% of adults. IFA/IFB, RSV A/B, and hMPV exhibited strong seasonal detection and similar circulating patterns in children and adults. Adult patients showed different clinical manifestations according to causative viruses; nasal congestion and rhinorrhea were more common in hRV and human coronavirus (hCoV) infection. Patients with RSV B, hRV, or AdV tended to be younger, and those infected with RSV A and hMPV were likely to be older. Those with RSV A infection tended to stay longer in hospital, enter the intensive care unit more frequently, and have a fatal outcome more often. The bacterial co-detection rate was 26.5%, and those cases were more likely to have lower respiratory tract involvement (P = 0.001), longer hospital stay (P = 0.001), and higher mortality (P = 0.001).ConclusionsThe etiologic virus of an acute respiratory infection can be cautiously inferred based on a patient's age and clinical features and concurrent epidemic data. Large-scale prospective surveillance studies are required to provide more accurate information about respiratory viral infection etiology, which could favorably influence clinical outcomes.

“…Dans les infections à rhinovirus le taux de co-infections virales varie de 5 à 40 % selon les auteurs [4,10,26]. Nous en rapportons 9 % dans cette étude.…”

“…Nous en rapportons 9 % dans cette étude. Il n'y a pas non plus de différence significative concernant l'âge, les affections néonatales, l'atopie, la gravité clinique, comme le notait également l'étude de Brouard et al [26]. Nous décrivons cependant un cas de bronchiolite à rhinovirus et VRS dont la gravité est probablement liée à l'association des deux infections virales.…”
