目的:分析儿童散发性诺如病毒性肠炎的临床特点。方法:选取120例散发性诺如病毒性肠炎患儿为诺如病毒性肠炎组,50例轮状病毒性肠炎患儿为对照组;诺如病毒性肠炎组年龄<3岁患儿分为婴幼儿组,年龄≥3岁患儿分为学龄前期组。所有患儿均在诊治当天行ELISA法检测大便诺如病毒和轮状病毒抗原,记录临床症状,同时行大便常规、末梢血血常规检查。结果:诺如病毒性肠炎组年龄主要分布于9个月~4岁2个月,临床表现中发热56例占46.7%,呕吐45例占37.5%,腹痛28例占23.3%。诺如病毒、轮状病毒性肠炎患儿临床主要表现均为腹泻、发热、呕吐,两者间临床表现差异无统计学意义(P>0.05)。婴幼儿组主要临床表现为腹泻、发热、呕吐,学龄前期组主要临床表现为腹泻、腹痛。结论:诺如病毒性肠炎婴幼儿主要临床表现为腹泻、发热、呕吐,学龄前期组主要临床表现为腹泻、腹痛。诺如病毒性肠炎和轮状病毒性肠炎依据临床表现很难鉴别。 Objective: To analyze the clinical features of children with sporadic norovirus viral enteritis. Methods: 120 children with norovirus enteritis were selected as norovirus enteritis group and 50 children with rotavirus enteritis as control group. The children with norovirus enteritis group <3 years old were divided into infants Child care group, age ≥ 3 years old children were divided into preschool group. All children were diagnosed on the day of diagnosis and treatment of Norovirus stool norovirus and rotavirus antigen, record the clinical symptoms, stool routine at the same time, peripheral blood routine examination. Results: The age of norovirus enteritis group mainly distributed in 9 months to 4 years and 2 months. The clinical manifestations included fever in 56 cases (46.7%), vomiting in 45 cases (37.5%) and abdominal pain in 28 cases (23.3%). Norovirus, rotavirus enteritis children are the main clinical manifestations of diarrhea, fever, vomiting, there was no significant difference between the clinical manifestations (P> 0.05). The main clinical manifestations of infants and young children group was diarrhea, fever and vomiting. The main clinical manifestations of preschool group were diarrhea and abdominal pain. Conclusions: The main clinical manifestations of Norovirus enteritis in infants are diarrhea, fever and vomiting. The main clinical manifestations of preschool children are diarrhea and abdominal pain. Norovirus viral enteritis and rotavirus enteritis according to clinical manifestations is difficult to identify.
