Pathogen composition and changes of blood infectious diseases in VCT population in Pingshan District,Shenzhen from 2019 to 2022
Objective To study the pathogen composition and changes of blood-borne infectious diseases among voluntary counseling and testing(VCT)population in Pingshan District,Shenzhen from 2019 to 2022,and to provide scientific basis for the accurate prevention and control of blood-borne infectious diseases among VCT population.Methods The human immunodeficiency virus(HIV)antibody in the VCT population was detected according to"Chinese AIDS Diagnosis and Treatment Guide(2018 edition)",Treponema pallidum(TP),hepatitis C virus(HCV)antibody and hepatitis B virus surface antigen(HBsAg)were detected by ELISA.The composition and change characteristics of the above 4 pathogens were analyzed.Results A total of 533 VCT samples were detected,the positive rate of pathogens was 21.76％,with no significant difference between different years(x2=4.166,P=0.244).The positive population was mainly middle-aged and young men with history of risk sexual behavior,but there was no significant difference in the positive rate among different demographic groups.The types of infection included single infection,double infection and triple infection.The differences in positive rate among HIV single infection(8.44％),TP single infection(9.01％)and HBsAg alone(7.88％),HCV infection(0.56％),HIV+TP infection(2.81％),HIV+HBsAg infection(1.31％),TP+HBsAg infection(0.38％)and HIV+TP+HBsAg triple infection(0.38％)were statistically significant(x2=153.311,P＜0.001),the difference of positive rate in single infection was not statistically significant(x2=0.208,P=0.901).Conclusion There were four kinds of blood-borne infectious disease pathogens in VCT population in Pingshan District of Shenzhen,2019-2022,and the difference of the positive rate of different infection types and the annual positive population composition changed mainly focused on the history of risk behavior.More prevention and control measures for blood-borne infectious diseases could be developed according to the above characteristics.
