IA was detected in 14 patients (20.3%), B in 38 (55.1%), RSV in 15 (21.7%) and B plus RSV in 2 (2.9%). 41 patients required hospitalization (59.4%). There was a statistically significant association between virus detection and the need for hospitalization, as well between the detected virus and the need for hospitalization. IA had a higher association with hospitalization (OD 3.66). Mean age was 60.35 years (SD 19). There were no statistically significant differences between the detected virus and the duration of hospitalization. There was no statistically significant association between the detected virus and the final outcome. Almost 10% (4/41) were admitted to an intensive care unit. In-hospital mortality rate was 7.7% (3/41). There were 9 cases of vaccine failure (31%), but no statistically significant association between final outcome and vaccination status.Conclusions: IA, IB and RSV were co-circulated and had common clinical outcomes. IA was the most prone to hospitalization. Detection of risk factors associated with each infection might help identify the most vulnerable patients and encourage more preventive measures.FootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA4566.This is an ERS International Congress abstract.
