Introduction: Whooping cough is a public health problem that mainly affects children under one year of age with highly lethal outcomes. It is a re-emerging disease, which is preventable by immunization. Objective: To analyze mortality and morbidity trends of whooping cough in Colombia between 2002 and 2012. Materials and methods: We conducted a quantitative descriptive study of deaths by pertussis between 2002 and 2012 using data from death certificates registered by the Departamento Administrativo Nacional de Estadística , and cases reported to the Sistema Nacional de Vigilancia en Salud Pública , 2005-2012. Frequency measurements, morbidity and mortality ratios and female increased mortality were calculated. Results: Fifty one point two percent of the deaths occurred in women; the year with more deaths was 2012; 67.3% occurred in urban areas, and 43.5% of the subjects were affiliated to the subsidized health regime. The risk of illness was 1.88 per 1,000 live births with increased risk in Vaupés and Vichada. The risk of death was 0.02 per 1,000 live births; there was a decrease in the lethality trend. Conclusions: Pertussis has reemerged with increasing mortality and morbidity. Since this is a preventable disease through vaccination, it is advisable to increase control and enhance vaccination coverage in both children and adults, who are an important reservoir of the disease. The effective control of pertussis demands continued work aimed at early identification. It is also necessary to carry out actions to improve data quality in order to facilitate its analysis and the generation of more valid information.
