Ethics approval and consent to participate
: This outbreak investigation was conducted by a public health agency according to the Guidelines on Outbreak Investigation, Prevention and Control of Norovirus Infection (2015) issued by the Chinese Centers for Disease Control and Prevention as part of a legally authorized mandate, and it was therefore exempted from ethics approval by the ethics review board of Jinshan District Center for Disease Control and Prevention. In addition, as the investigation was an urgent public health response to the outbreak and interviewing and sample collection posed minimal risks, written informed consent was waived by the ethics review board of Jinshan District Center for Disease Control and Prevention. Instead, oral informed consent was obtained from each participant on the spot or, for those aged < 16 years, from their parents or legal guardians by phone call prior to the interview.
