Official title:
Seroepidemiological Study of Pertussis and Other Infectious Diseases
Serum samples will be corrected twice from the same youth subjects with one year interval.

an identical individual.
The relationship between the incidence and the demographic data or medical history of the
subjects will be discussed.
