“…The incidence of pertussis dramatically declined in developed countries following childhood vaccination programmes initiated in the 1940s-1960s. However, doubts remain over the consequences of pertussis immunization for transmission, as opposed to disease (Das 2002), with concerns about whether declining incidence in the vaccine era truly reflects reduced transmission or reduced clinical symptoms following infection (Fine & Clarkson 1982;Aguas et al 2006). This distinction is especially important for understanding and managing the recent rise in reported cases that has been recently documented in countries with long vaccination history, together with an increasing proportion of cases in adolescents and adults, including those previously vaccinated (Wirsing von König et al 1995;Guris et al 1999;Senzilet et al 2001;Gilberg et al 2002;Hellenbrand et al 2009).…”

“…En ocasiones su forma de presentación varía, especialmente en pacientes bajo seis meses de edad o sin una inmunización completa [4][5][6][7][8] . En estos pacientes se puede desarrollar una coqueluche grave (CG), definida como falla respiratoria, hipoxemia refractaria e hipertensión pulmonar (HTP), la cual presenta una elevada tasa de morbi-mortalidad asociada.…”

“…Desde la década pasada se ha observado un aumento significativo de los casos, incluso en países desarrollados con buenas coberturas de vacunación 3 . No obstante, comparar la incidencia de esta enfermedad entre los distintos países es difícil, ya que depende de las diferencias entre la definición de caso, acceso a pruebas diagnósticas, experiencia médica para identificar su cuadro clínico y si la enfermedad es de declaración obligatoria según la normativa de salud pública de cada país.En ocasiones su forma de presentación varía, especialmente en pacientes bajo seis meses de edad o sin una inmunización completa [4][5][6][7][8] . En estos pacientes se puede desarrollar una coqueluche grave (CG), definida como falla respiratoria, hipoxemia refractaria e hipertensión pulmonar (HTP), la cual presenta una elevada tasa de morbi-mortalidad asociada.…”

“…However, the two key factors held responsible for the pertussis resurgence in vaccinated populations are, on the one hand, the appearance of new B. pertussis strain variants, and on the other hand, the gradual loss of vaccine-induced protective immunity in vaccinees, in an era of less circulation and natural boosting (Figure 1). The relative impact of these factors in the resurgence of pertussis is under investigation and may differ between subpopulations and countries [35][36][37][38].…”
