Abstract:
Objective To analyze the epidemiological characteristics and the detection of pathogenic microorganisms in the cases of foodborne diseases under active surveillance in Xi'an, and to provide references for prevention and control of foodborne diseases. Methods Information on surveillance cases of foodborne diseases reported by two sentinel hospitals in Xi'an from 2017 to 2019 was collected. Data was statistically analyzed. Results From 2017 to 2019, a total of 904 cases of active surveillance of foodborne diseases were reported by two active surveillance sentinel hospitals in Xi'an. There were more cases in the age groups of 1-5 and 5-8, accounting for 35.18% and 20.02%, respectively. There was a statistically significant difference in the number of cases reported in four quarters（χ2=545.38，P<0.05）. The majority of cases were reported in the third quarter, accounting for 53.76% of the total. The majority of suspicious foods were mainly mixed foods and the most suspicious dining places were families. Of the 901 samples, 251 were positive with a positive rate of 27.86%. There was a statistically significant difference in the detection ratio of different foodborne pathogens（χ2=321.92，P<0.05）. The detection rates of Norovirus and salmonella were higher, accounting for 14.98% and 11.43%, respectively. There was a statistically significant difference in the detection rate of Salmonella in different seasons（χ2= 26.49，P<0.05）, and the detection rates were higher in the second and third quarter. There was also a statistically significant difference in the detection rate of Norovirus（χ2=92.17，P<0.05） in different seasons, and the detection rate was higher in the first and fourth quarters. Conclusion The main pathogens of food-borne diseases are Norovirus and Salmonella in Xi'an. It is suggested that active surveillance should be strengthened. The prevention and control knowledge of foodborne diseases should be carried out according to the epidemiological characteristics.
