Background: Viral gastroenteritis is a significant global health concern. An effective, rapid, and easy-to-use diagnostic tool is essential for screening causative viruses.
Methods: Forty-eight samples, known to be infected with one of the following viruses: norovirus, group A rotavirus, astrovirus, adenovirus, and sapovirus determined by reverse transcription-PCR and nucleotide sequencing, were evaluated by the Fast Track Diagnostics (FTD) viral gastroenteritis assay.
Results: The assay demonstrated 100% specificity for all viruses and matched the RT-PCR sensitivity for norovi-rus GI, classic human astrovirus, adenovirus, and sapovirus. It identified norovirus GII and rotavirus with 87.5% and 85.7% sensitivity, respectively. However, its sensitivity for detecting novel human astrovirus MLB and VA was lower, at 35%.
Conclusions: The FTD viral gastroenteritis assay can effectively screen simultaneously for norovirus GI, GII, group A rotavirus, adenovirus, and sapovirus in clinical settings. The study also suggests that improved detection methods are necessary for novel astrovirus strains.
