Abstract

To measure the seroprevalence of high-exposure populations in brucellosis endemic areas and report the outcome and duration of seropositive asymptomatic subjects, we screened 595 family members of shepherds in Jilin Province, China and then followed up 15 seropositive asymptomatic subjects for 18 months. We found that the seropositive rate of 15.5%. Nearly half of seropositive asymptomatic subjects (7/15) developed into brucellosis in the short term; others were still seropositive asymptomatic or had decreased SAT titer in a longer time.
