Methods data of the outbreak of norovirus gastroenteritis in schools in Zhejiang Province from January 2011 to January 2015 were selected in the network reporting system of public health emergencies in Zhejiang Province. The time, region and population distribution of the outbreak were analyzed. The transmission routes and genotypes of the virus were compared with the average levels of Zhejiang Province and the whole country in the same period from 2004 to 2010.
