Methods a total of 116 pregnant women with vomiting and diarrhea were selected. Their clinical manifestations and epidemic characteristics were investigated and analyzed. Norovirus in stool samples of pregnant women was detected by polymerase chain reaction (PCR). Results among 116 pregnant women, 50 cases had diarrhea with vomiting, 51 cases had diarrhea and 15 cases had vomiting. The results of nucleic acid detection showed that 42 cases were positive and 74 cases were negative. Among the 42 pregnant women with positive nucleic acid results, 26 were multipara and 16 were primipara; There were 3 cases of early pregnancy (7.1%), 9 cases of middle pregnancy (21.4%) and 30 cases of late pregnancy (71.4%). Diarrhea with vomiting in 28 cases, accounting for 66.7%. Conclusion pregnant women are more likely to be infected with norovirus, and most of them have mild symptoms such as diarrhea and vomiting.
