[Immunization of adolescents and adults as the strategy of improvement of epidemiology of pertussis].

Increase of pertussis incidence has been recognised mainly among adolescents and adults since 90. As adolescents and adults sustain the reservoir of infection for non immunized and not completely immunized newborns and neonates, increased rates of pertussis are dangerous. The improvement of pertussis epidemiology might have been obtained through routine immunization of adolescents and adults able to interrupt of B. pertussis circulation in the population. The improvement of surveillance and diagnostics might have result in better detection of the disease in children at the age up to first year and in older age groups.
