Abstract

We have performed an epidemiological analysis of adult patients hospitalized with influenza A/H1N1 in the year 2009 in the Pulmonology Service of La Paz University Hospital in Madrid, Spain. We carried out a retrospective cohort and descriptive study in La Paz University Hospital from July to December 2009 of 102 patients diagnosed with Influenza A in the first 24 h of their stay in the Emergency Unit. All patients included in this study were those who were admitted in the Pulmonology Service. We did not include patients who died in the Intensive Care Unit (ICU).There included 45 women (44.12%) and 57 men (55.88%) with a mean age of 41.40 ± 1.67 years. The mean days of hospitalstay was 6.20±1.02 days. Among the comorbidities, the most frequents were inmunossupresion, neoplasia and diabetes mellitus. The predominant symptomatology was cough, expectoration, fever and myalgia. In three cases, the patient was pneumococcical pneumonia. Radiograph abnormalities were found in 43 patients (45.26%) with diagnosis of Influenza 2009 H1N1. It was detected in 35 (36.84%) patients an alveolar pattern and other patterns were found.   We think that this epidemic viral flu by H1N1 has permitted to know that viruses can be an important problem in the world health.
