Objective To analyze the causes and infection sources of a clustering outbreak of influenza b in a rural primary school in Gaozhou in 2012,and to provide scientific support for the prevention and control of this flu.Methods Epidemiological analysis was conducted by using flu case questionnaires,findings of laboratory test,and hygiene data.Results The clustering outbreak began in February 18,2012,with unknown infection sources for first cases,and the last case occurred in February 21.Of 263 people with exposure to infection,9 developed flu,with a attack rate of 3.4％,no death occurred.The age distributed in the age group of 13 to 14,without gender differences.Because the first patient was resident student,the attack rate for the resident students was much higher than that for non-resident students.6 of 9 patients were positive for nucleic acid detection in flu virus.Conclusions It was a clustering outbreak of hepatitis b influenza and the transmission way was airborne.Early detection,reports,isolation,and vaccination of flu vaccine are the key measures to control influenza outbreak.
