Abstract

The introduction of routine vaccination against Bordetella pertussis led to a drastic decline in the number of reported cases of pertussis. Nevertheless, a gradual increase in pertussis notifications has been observed in the last years, and political vaccination changes have been conducted in some countries. Pertussis epidemiology is reviewed, taking into account mathematical models studies concerning new vaccinal strategies for pertussis prevention and new international recommendations. Regarding Portugal, the need for a “booster” in adolescence is emphasized, and other recommendations for pertussis control are suggested.

Key-words:

Resumo

A introdução da vacina antipertussis nos programas de vacinação originou uma diminuição drástica da incidência de tosse convulsa no mundo. No entanto, nos últimos anos tem-se observado um aumento gradual do número de notificações, facto que já levou vários países a reformularem estratégias vacinais para esta doença. Foi efectuada uma revisão epidemiológica da tosse convulsa, realçando estudos baseados em modelos matemáticos que tentam prever o impacto de novas estratégias vacinais e novas recomendações internacionais. Tendo em conta a realidade portuguesa, alerta-se para a necessidade de um reforço vacinal na idade da adolescência e sugerem-se outras recomendações para um melhor controlo da tosse convulsa no nosso país.
