Serological analysis on food borne parasitic diseases of outpatients and healthy people in Shenzhen City
Objective To analyze the epidemic situation and trend of food-borne parasitic diseases in Shenzhen City thus to supply a scientific basis for developing the control strategies.Methods Serum samples of the outpatients at Shenzhen Centre for Disease Control and Prevention and healthy people were collected during January to December 2013.The specific antibodies of Clonorchis sinensis,Paragonimus,Angiostrongylus cantonensis,Cysticercus,hydatid and Sparganum in the samples were detected with ELISA.The characteristics of parasite infection was analyzed using descriptive epidemiological method.Results The total positive rate of food borne parasitic diseases was 24.35％(76/312).The rates of Clonorchis sinensis,Paragonimus,A ngiostrongylus cantonensis,Cystecercus,hydatid and Sparganum were 12.01％(31/258),6.98％(16/229),6.19％(13/210),8.75％(21/240),5.37％(11/205) and 9.20％(23/250) respectively in those 312 outpatients.The gender distribution of the total positive cases was 27.33％ (44/161) in male and 21.19％ (32/151) in female with no significant difference (x2=1.593,P＞0.05).As to the age distribution of the total positive rates,the highest rate group was 21-50 years old group,however there was no significant difference between different age groups (x2=4.376,P＞0.05).The total positive rate was 8.80 ％ (44/500) in 500 healthy people.The positive rates of above six parasites were 2.80％ (14/500),1.60％ (8/500),2.00％ (10/500),2.40％ (12/500),1.80％(9/500) and 2.20％ (11/500) respectively.The total positive rate was 9.67％ (25/258) in male,higher than that 7.85％ (19/242) in female,however the difference was not significant (x2=0.526,P＞0.05).As to the age distribution of the total positive rates,the highest rate was also in 21-50 years old group,while the difference between different age groups was significant (x2=8.625,P＜0.05).Overall,the total positive rate in outpatients was significantly higher than that in healthy people (x2=36.928,P＜0.05).Conclusion The infection rates of food borne parasitic infections in the outpatients is higher than that in healthy people in Shenzhen and the food-borne parasitic diseases were the major parasitic diseases to be prevented in Shenzhen areas and the healthy diet habit should be widely educated.
