Seroepidemiological Study of Pertussis and Other Infectious Diseases
Serum samples will be corrected twice from the same youth subjects with one year interval.
Seroincidence of pertussis will be estimated by the elevation of Ig-G-PT in paired sera from an identical individual.
The relationship between the incidence and the demographic data or medical history of the subjects will be discussed.
