Sumario:OBJECTIVE: In December 2017, an acute gastroenteritis outbreak involving 61 students occurred in a boarding high school in Beijing, China. We conducted an outbreak investigation immediately in order to determine the cause of this outbreak and provide effective control measures. RESULTS: The laboratory inspection showed that this outbreak was caused by GII.P16-GII.2 norovirus. Risk factor analysis indicated that the lunch provided by Cafeteria 1 on Dec 12 might be the risk factor of the outbreak with an odds ratio (OR) of 3.800 (95% confidence interval [CI] 1.089–13.258). Additionally, a tray line server of Cafeteria 1 was found to have gastro-enteral symptoms recently. Based on the clinical symptoms and epidemiology investigation, the symptomatic server was considered to be the possible source of infection.
