Abstract:

Objective

To analyze the situation of Brucella infection in Shanxi province from 2020 to 2021, and provide a reference basis for the prevention and control of brucellosis in Shanxi province.

A retrospective analysis was conducted on the results of Brucella testing using the Rose-Bengal Plate Test (RBPT) and Standard-tube Agglutination Test (SAT) for 4265 suspected cases awaiting diagnosis.

Results

The annual average positive rate of Brucella in Shanxi province increased from 18.39% in 2020 to 19.41% in 2021. According to regional statistical analysis, the positive rate in Xinzhou and Lyuliang is over 28.17%, while the positive rate in Linfen and Yuncheng areas increased from 15.49% to 24.15%. In the age group analysis, it is mainly concentrated between the ages of 41 to 60, with a positive rate of over 23.81%. The positive rate for the 31~40 age group increased from 13.61% to 20.71%.

Conclusions

Brucella infection is on the rise in Shanxi province, with a trend of increasing positive rates in young and middle-aged population. Brucellosis has the tendency of spreading from the northern regions to the southern regions. As well as the southern areas of Linfen and Yuncheng, active propaganda, education, and control measures needed in the northern areas of Lyuliang and Xinzhou.
