Preliminary evaluation of BioFire FilmArray(A (R)) Gastrointestinal Panel for the detection of noroviruses and other enteric viruses from wastewater and shellfish


Results: Influenza virus infection was confirmed in 28% of GW hospital and 41% of ICU patients; influenza vaccination was documented for 56% and 41%, respectively. Across seasons, IVE was 37% (95% confidence intervals [CI] = 23-48%) among GW patients and 82% (95% CI = 45-94%) among ICU patients. IVE point estimates were > 70% against ICU influenza and consistently higher than IVE against GW influenza when stratified by season, by virus (sub)types, and for adults with or without chronic medical conditions and for both adults aged <65 and >= 65 years old.
