Summary: Background: Respiratory tract infection is one of the most common causes of seeking medical attention. Viruses are among the most common etiologic al agents of viral pneumonia, with apercentage that ranges between el 5 and 34%. In Costa Rica there are no epidemiological studies that describe the percentage of pneumonias associated to viral infections in hospitalized patients. Given the investment in in patient days and use of antibiotics, it is important to know what is the percentage of viral infections. Methods: The methodology was based on an observational retrospective cohort throughpatient files review. The primary outcome was to identify the prevalence of viral infection in the population hospitalized for community acquired pneumonia. The study was conducted at the Hospital Dr. Rafael Angel Calderon Guardia, during the months from May through September 2009. Findings: Out of 320 patients, 59 were included in the study. Viral infection was found in 18,4%.Most patients were healthy adults under 40 yearsold. Influenza A H1N1 was the most commonvirus in 50,8% of cases (n=30). The most frequent comorbidities were hypertension (20,3%) and asthma (13,6%). Patients with viralinfection had important elevation in biomarkers such as LDH, CPK, ALT, AST and creatinine. Conclusion: Viral infection in community acquired pneumonia is frequent. Measures to identify patients with pandemic Influenza influenced the high percentage of cases found inour cohort.
