Studies to Control Endemic Typhoid Fever in Chile
Abstract
A multi-faceted program of applied research has been undertaken to lead to control of endemic typhoid fever in Santiago, Chile. These studies include: 1) Maintenance of prospective epidemiologic and bacteriologic surveillance in three large-scale field trials evaluating the efficacy of Ty21a live oral typhoid vaccine given in various formulations and immunization schedules. 2) The first evaluations of Ty21a vaccine in infants and pre-school children. 3) Development of a new enzyme-linked immunosorbent assay (ELISA)to measure Vi antibodies and its use as a serologic screening test to identify chronic typhoid carriers. 4) Evaluation of a new oral antibiotic regimen to eradicate the chronic typhoid carrier state without resort to surgery.
