Serological Prevalence Survey Among The High-Risk Populations Of Brucellosis-Endemic Areas - China, 2019-2020

What is already known about this topic?Timely screening of high-risk population is important to improve the early detection of brucellosis among the endemic areas during the high incidence seasons, which is also required by the National Brucellosis Prevention and Control Plan (2016-2020) (NBPCP).What is added by this report?Seroepidemiological characteristics of brucellosis in high-risk populations were obtained and special occupational populations were found. The seroprevalence of brucellosis has been decreasing compared with that reported in the recent years due to the ongoing implementation of control measures in endemic areas.What are the implications for public health practice?Special occupational populations could be promptly detected using routine screening, which makes it possible to initiate standardized treatment for infected patients as early as possible. It also reminds us to pay attention to special occupational populations to improve their knowledge of brucellosis and reduce the risk of infection.
