Objective To provide scientific basis for the effective control of the epidemic by investigating the sources of communication and possible ways of transmission. Methods Epidemiological investigation, hygiene investigation, risk factors explore and outbreak causes were carried out according to the outbreak investigation steps. Results A total of 62 suspected cases had significant clinical symptom of adenovirus, and the main clinical symptoms of 62 suspected cases were fever, pharyngitis accounted for 80% (48/62), cough accounted for 56.45% (35/62), and conjunctivitis accounted for 25.81% (16/62). The laboratory test results showed that 60 cases were positive of adenovirus nucleic acid, and cases had swimming history of natatorium, indicating that the swimming pool might be the cause of outbreak. Conclusion The investigation showed that this outbreak occurred in swimming pool was infected by adenovirus. Thus, we should strengthen the supervision of public places, and carry out effectively implement disinfection measures without delay.
