Abstract: Objective To understand the epidemiological characteristics of norovirus gastroenteritis in Jilin province during 2013-2015 and provide evidence for the prevention and control of norovirus gastroenteritis outbreak. Methods Descriptive epidemiological analysis and statistical test were conducted by using the surveillance data of viral diarrhea in Jilin during this period. Results A total of 2489 suspected cases of viral diarrhea were reported during this period, in which, 389 were norovirus nucleic acid positive (15.63%), including 16 norovirus GⅠ infections, 371 norovirus GⅡ infections, 2 norovirus GⅠ and GⅡ co-infections. The detection rate of norovirus GⅠ was 0.72% (18/2489), and the detection rate of norovirus GⅡ was 14.99% (373/2489). The norovirus detection rate was higher in 2015 than in 2013 (P=0.030). The norovirus detection rates were higher in the first and second quarters (31.00%, 18.66%) than in the third and fourth quarters (P=0.000).The monthly norovirus detection rates during December to May (27.59%, 30.22%, 36.36%, 27.39%, 25.33%, 19.70%) were higher than those in other months.There were no significant gender(P=0.374)and area(P=0.122) specific differences in norovirus detection rate, but the age specific difference had significance (P0.01). The age specific detection rates were high in those aged 85 years (22.73%) and aged 5 years (18.90%), and the population specific detection rates were high in those engaged in commercial service (44.44%) and children(18.11%) (P=0.001). Conclusion In Jilin province, the norovirus infection rate increased year by year from 2013 to 2015, and the detection rate were higher in first and second quarters than in third and fourth quarters. Norovirus GⅡ was predominant. The elderly, children, people engaged in commercial service were prone to be infected.
