Pertussis or whooping cough is far from eradication, and the incidence is increasing in our environment. Although mortality rate is less than 1%, the morbidity is high, and involves a high cost to society. The aim of this study is to estimate the rate of hospital admissions in children due to whooping-cough in a peripheral area in Madrid. We carried out a retrospective epidemiological survey. Data were obtained by review of clinical electronic history. All hospital discharges in children under 5 (ICD-9-CM 033) between January 2008 and December 2012 were analyzed. We estimated the annual incidence of hospitalization for pertussis and average length of stay. The annual incidence during the period of the study was 34 per 100,000 children under 5. Up to 25% of the cases occurred at 2011. 100% of children were less than 1 year of age; average age: 3.1 months (SD= 1.6). More than half (56%) concerned symptoms in the near-family. Average length of stay was 6.1 days (SD= 3.5). 6.2% of patients needed critical care assistance. There were no mortality cases. Rate of hospital admissions in children under 5 years due to whooping-cough is increasing.
