A study of respiratory infections in the elderly to assess the role of respiratory syncytial virus

Abstract

A prospective study was performed from 1 December 1981 to 31 May 1982 in two departments of geriatric medicine in Edinburgh. This yielded 159 cases of acute respiratory tract infection (RTI). Twelve of these were undoubtedly associated with respiratory syncytial virus (RSV), 14 with influenza A and 18 with influenza B (as established in each case by a fourfold or greater increase in antibody titre). Eighty-five of the 159 patients with RTI and RSV titres of 32 or greater. Their significance is discussed. The undoubted RSV infections all involved the lower respiratory tract and were associated with prolonged illness. This epidemic of RSV infection was confined to one of the two hospitals. It lasted less than four weeks and was probably hospital-acquired.
