Abstract:
Objective To analyze the epidemiological characteristics of an outbreak caused by respiratory adenovirus in a university,and study the factors of respiratory adenovirus outbreak and ways of prevention and control.Methods The pharyngeal swabs of each case were identified by real time-PCR and sequencing.All the epidemiological and clinical information of these cases was collected via field interviews and medical records.Epidemiological characteristics of the outbreak were analyzed descriptively.Results 193 cases,including 89 cases of pneumonia,from a total of 807 cases,were admitted to the hospital.The incidence was 32.79%(807/2461).798 adenovirus positive samples were detected from 2461 pharyngeal swab samples.The total positive detection rate was 32.42%(798/2461).The positive rate of adenovirus was 98.88%(798/807).Clinical symptoms included fever(95.7%), cough(76.9%)and sore throat(52.2%).The outbreak was brought under effective control after integrated intervention measures were taken.Conclusion Respiratory adenovirus often causes outbreaks in crowded populations.Early symptomatic surveillance and standardized laboratory detection methods are crucial for prevention and control of outbreaks.Integrated control measures should be taken according to the field conditions and characteristics of the outbreak.
