Burden and viral aetiology of @entity683 and XXXX in intensive care units.

@entity1 @entity683 @entity1729 @entity281
UNASSIGNED: The purpose of this investigation was to study the viral aetiology of @entity683 ( @entity683 ) and acute @entity1729 (ARTI) among @entity1 requiring intensive care unit admission. A cross-sectional retrospective study was carried out in Sicily over a 4-year period. A total of 233 respiratory samples of @entity1 with @entity683 /ARTI admitted to intensive care units were molecularly analyzed for the detection of a comprehensive panel of aetiologic agents of viral @entity1729 . About 45% of @entity1 was positive for at least one pathogen. Single aetiology occurred in 75.2% of infected @entity1 , while polymicrobial infection was found in 24.8% of positive subjects. Influenza was the most common aetiologic agent (55.7%), especially among adults. Most of @entity1 with multiple aetiology (76.9%) were adults and elderly. Mortality rates among @entity1 with negative or positive aetiology did not significantly differ (52.4% and 47.6%, respectively). Highly transmissible respiratory pathogens are frequently detected among @entity1 with @entity683 /ARTI admitted in intensive care units, showing the occurrence of concurrent @entity281 by different viruses. The knowledge of the circulation of several types of microorganisms is of crucial importance in terms of appropriateness of therapies, but also for the implication in prevention strategies and hospital epidemiology.
