Monitoring and Epidemic Analysis of Key Populations of Brucellosis in a Certain Region From 2021 to 2022
Objective To explore the monitoring results of Brucellosis among key populations in Shaowu City,Fujian Province from 2021 to 2022.Methods A study was conducted on 492 key populations who underwent serological testing for brucellosis in Shaowu City from January 2021 to December 2022.5 mL of the patient's venous whole blood and extract serum were collected.According to the Chinese health industry standard"Diagnosis of Brucellosis"(WS269-2019),brucella was initially screened and confirmed using tiger red plate agglutination test(RBT)and in vitro agglutination test(SAT),respectively.Retrospective investigation of the test results of the subjects and statistical analysis of the positive rate.At the same time,investigate the awareness of brucellosis prevention and control knowledge and the use of protective equipment among the test subjects,and calculate the awareness rate of prevention and control knowledge and the qualified rate of protection.Results From 2021 to 2022,a total of 24 cases of brucellosis were detected,including 4 slaughterers,1 herder and 1 invoicer,18 fever patients,and a positive detection rate of 4.88%.Among them,the positive detection rate of brucellosis in 2022(1.46%)was lower than that in 2021(9.17%),with a statistically significant difference(P<0.05).The proportion of highly knowledgeable individuals in the prevention and control of brucellosis was only 15.45%,and the proportion of positive individuals with high and moderate knowledge in the prevention and control of brucellosis was lower than that of negative individuals.The correct self-protection rate for brucellosis exceeded 80%,but the correct self-protection rate for brucellosis in positive individuals was lower than that in negative individuals,with a statistically significant difference(P<0.05).Conclusion The infection rate of brucella among key populations in Shaowu City,Fujian Province from 2021 to 2022 is not high and shows a decreasing trend.However,it is still necessary to carry out health promotion and education on brucella disease prevention and control knowledge for key populations,further improve their awareness and skills of brucella disease prevention and control,strengthen occupational protection effects,and further reduce the risk of brucella infection to better ensure the occupational safety of key populations.
