ABSTRACT
BACKGROUND:
Norovirus outbreaks have a significant impact on all care settings; little is known about the index cases from whom these outbreaks initiate.AIM:
To identify and categorise norovirus outbreak index cases in care settings.METHODS:
A mixed-methods, multi-centre, prospective, enhanced surveillance study identified and categorised index cases in acute and non-acute care settings.RESULTS:
From 54 participating centres, 537 outbreaks were reported (November 2013 to April 2014) 383 (71.3%) in acute care facilities (ACF); 115 (21.4%) in residential or care homes (RCH) and 39 (7.3%) in other care settings (OCS). Index cases were identified in 424 (79%) outbreaks. Of the 245 index cases who were asymptomatic on admission and not transferred within/into the care setting, 123 (50%) had been an inpatient/resident for 4 days. Four themes emerged missing the diagnosis, care service under pressure, delay in outbreak control measures and patient/resident location and proximity.CONCLUSION:
The true index case is commonly not identified as the cause of a norovirus outbreak with at least 50% of index cases being misclassified. Unrecognised norovirus cross-transmission occurs frequently suggesting that either Standard Infection Control Precautions (SICPs) are being insufficiently well applied, and or SICPs are themselves are insufficient to prevent outbreaks.
