Introducción: La tosferina ha aumentado su incidencia y severidad especialmente en lactantes, por lo que la vacunación de la embarazada se ha introducido como estrategia preventiva. La pandemia de la COVID-19 parece haber disminuido la incidencia de distintas enfermedades respiratorias. Métodos: Estudio retrospectivo entre 2012-2021, analizando la influencia de la vacunación de la embarazada y del primer año de la pandemia de la COVID-19 en los casos de tosferina. Resultados: Se incluyeron 960 pacientes de atención primaria y hospitalaria con sospecha de tosferina, con 130 casos diagnosticados (104 niños y 26 adultos). En el periodo posvacunal, se observó una disminución de casos y de severidad de la tosferina en niños menores de 6 meses y de los diagnósticos en mujeres adultas. No se detectó ningún paciente con tosferina durante el periodo de la COVID-19. Conclusión: Tanto la vacunación de la embarazada como el primer año de la pandemia de la COVID-19 han disminuido significativamente los casos de tosferina.(AU)

There were no whooping cough cases during the COVID-19 period. Conclusions: Both the pertussis vaccination in pregnancy and the first year of the COVID-19 pandemic have decreased the number of pertussis cases.(AU)
