The seroprevalence of cysticercosis, malaria, and Trypanosoma cruzi among North Carolina migrant farmworkers.

A seroprevalence study of cysticercosis, Trypanosoma cruzi, and plasmodia species and screening for active malaria was conducted among a randomly selected group of 138 Hispanic and Haitian migrant farmworkers. A random sample of labor camps in eastern North Carolina was selected. Blood samples were test by Indirect Fluorescent Antibody techniques for plasmodial antibody and by enzyme-linked immunosorbent assay (ELISA) for cysticerci and T. cruzi antibodies. Questionnaires collected demographic data and medical history of the workers and family.A seroprevalence study of cysticercosis, Trypanosoma cruzi, and plasmodia species and screening for active malaria was conducted among a randomly selected group of 138 Hispanic and Haitian migrant farmworkers.
