AB  - Factors affecting the seasonal distribution of norovirus outbreaks are not well 
      understood. This study examined whether grade school settings at the start of the 
      school year may be a factor. We searched Ovid Medline from January 2002 to June 
      2014 for studies that provided all reported norovirus outbreaks in a developed 
      country by month for a minimum of three years. Historical school years were 
      obtained from verifiable sources. The start of the norovirus seasonal outbreak 
      peak and peak outbreak month were determined for each study and compared to the 
      start month of school. Northern hemisphere and southern hemisphere countries had 
      a different norovirus seasonality and different school year structures 
      (traditional compared to year round). In the two studies that provided outbreaks 
      by age, outbreaks among children started several months before outbreaks in the 
      adult population. The median number of months between school start and start of 
      the seasonal outbreak peak was two months (interquartile range [IQR] = 2.0-3.0), 
      while the median number of months between school start and peak outbreak month 
      was four months (IQR = 3.0-4.0). These findings suggest the possibility the 
      school setting at the start of the school year may be a factor in the seasonality 
      of norovirus.
