Rol del virus sincicial respiratorio en una cohorte de adultos mayores

The role of respiratory viruses other than influenza in acute respiratory tract infections among elderly adults has probably been underestimated. Recent advances in molecular diagnosis have made the rapid identification of human respiratory syncitial virus HRSV infection possible. We conducted a prospective observational study to evaluate the role of HRSV in elderly patients (>65 years of age) hospitalized for acute respiratory infections. A total of 124 patients were recruited, HRSV infection was identified in 13 patients, Influenza B in 9 patients and influenza A in 8 patients. The most frequent clinical presentation was bronchospasm and the infection was prevalent in patients with comorbidities. HRSV infections accounted for an important number of hospital admissions and has been associated with high mortality rates (23%).
