Abstract：Objective To make epidemiological investigation and pathogen detection for an outbreak of acute respiratory infec-tion in a school, so as to confirm the diagnosis and to control the epidemic. Methods A field epidemiological investigation was con-ducted to search and verify the cases, and the characteristics of the epidemic was analyzed. The case-control study was made to analyze the risk factors. The throat swabs were collected and the RT-PCR was used to detect nucleic acids of the virus. Results Forty-three cases were found in the outbreak of acute respiratory infection, with the attack rate of 1.3%in the students. The cases came from 4 classes, which suggested a clear clustering. The case-control study showed the risk factor was the contact with the cases. The throat swabs from 12 cases were collected and the detection of the nucleic acids showed that 8 swabs were positive for adenovirus. Conclusions The out-break of acute respiratory infection among students in the school is caused by adenovirus. The main mode of transmission is close con-tact among the students.
