چکیده

OBJECTIVE To assess whether changes in vaccination policy have affected the epidemiology of pertussis in NSW between 1993 and 2005. METHODS Surveillance data from the NSW Notifiable Diseases Database was reviewed for the period. RESULTS 35,695 cases of pertussis were notified; annual incidence rates varied from 18.4 to 84.2 per 100,000 people. The highest rates of pertussis were consistently found in infants aged 0-6 months. Rates of disease in other age groups changed markedly over the study period, with high rates currently observed in adult age groups. CONCLUSIONS New strategies may be needed to control pertussis in infants and in adults who now comprise the largest proportion of cases.

Prior to 1999, a formulation that included whole cell pertussis vaccine was used. In NSW, period...

The changing epidemiology of pertussis in the Hunter New England area and potential implications for the immunisation schedule.

A complete understanding of the epidemiology of Bordetella pertussis is complicated by imperfect diagnostic methods and incomplete recognition, testing and notification of the disease. It is generally agreed that notification rates represent an under-reporting of actual incidence. However, Australia has improved surveillance for pertussis since the early 1990s and currently has the highest repo...

Bug breakfast in the Bulletin. Pertussis in NSW and its prevention in infants and children.

Epidemiology In countries with universal childhood vaccination, epidemics of pertussis occur periodically on a background of endemic circulation, although levels of disease activity are much lower in comparison to those in unimmunised populations. In NSW and nationally, a large epidemic unfolded from 2008. In 2008–2009, the pertussis notification rate in NSW was about three times higher than th...
