[Assessment of two methods of antigenic detection by ELISA for the diagnosis of norovirus outbreaks].
BACKGROUND
The aim of this study was to assess two ELISA techniques for the detection of outbreaks of norovirus.


METHODS
One-hundred and sixty-five fecal samples from patients affected in 30 outbreaks were studied.


RESULTS
On the basis of a specific consensus criterion between techniques for confirming outbreaks, the sensitivity and specificity was respectively 80% and 90% for RIDASCREEN, and 80% and 100% for IDEIA.


CONCLUSIONS
These techniques could be useful for rapid detection of norovirus outbreaks in laboratories that lack molecular confirmation techniques.
