Objective To understand the epidemiological characteristics of diarrhea virus in diarrhea patients in Taizhou from 2013 to 2015. Methods A total of 1 262 samples of diarrhea patients in Taizhou were collected from 2013 to 2015. Six kinds of diarrhea cases of adenovirus, rotavirus, Norovirus Ⅰ and Ⅱ, Astrovirus and Zha-ru virus were detected by fluorescence quantitative PCR. Virus detection, and analysis of the trend of each virus. Results A total of 298 positive samples were positive for fecal samples from 1 262 diarrhea patients, with a positive rate of 23.61%. Among them, adenovirus accounted for 3.96%, rotavirus accounted for 4.52%, Norovirus type Ⅰ accounted for 0.95% Virus type Ⅱ accounted for 9.98%, astrovirus accounted for 3.25%, Sapporo virus accounted for 0.95%. Viral diarrhea occurred throughout the year, but the incidence of winter and spring is higher, and 0 to 10 years old group is more susceptible to viral diarrhea. Conclusions In 2013-2015, diarrhea patients in Taizhou City were all year-old with viral diarrhea, mainly dominated by Norovirus type Ⅱ.
