Infection/exposure status changes based on sero-antigen and sero-antibody analysis throughout the study period.

R1, R2 and R3 stand for first, second and third rounds of sampling. N and P stand for negative and positive test result, respectively. Ag-ELISA: detection of circulating cysticercus antigen in serum. “No.” expresses the number of participants that presented the given statuses (e.g. N N N) during the follow up (e.g. 680 participants tested negative at all three sampling rounds, N N N); EITB: detection of specific antibodies in serum “No.” expresses the number of participants that presented the given statuses during the follow up (e.g. 72 participants of the 161 tested negative at all three sampling rounds, N N N. This number is independent of the Ag-ELISA result).
