Background: Acute exacerbations of chronic obstructive pulmonary disease (AE-COPD) are
a common cause of hospital admission. Many exacerbations are believed to be due to upper …

Respiratory viruses are associated with severe acute exacerbations of chronic obstructive
pulmonary disease (COPD) in hospitalized patients. However, exacerbations are …

BACKGROUND: Few studies have evaluated the contribution of both viruses and bacteria in
acute exacerbation of chronic obstructive pulmonary disease (AECOPD). OBJECTIVES: This …

OBJECTIVES: The purpose of the present study was to apply reverse transcription-PCR (RT-
PCR) assays to clinical specimens collected from patients with acute respiratory illness and …

The effects of respiratory viral infection on the time course of chronic obstructive pulmonary
disease (COPD) exacerbation were examined by monitoring changes in systemic …

BACKGROUND: Patients with COPD have frequent exacerbations. The role of respiratory
viral infection is just emerging. We wished to determine prospectively the incidence of viral …

The role of viruses in Acute Exacerbations of Chronic Obstructive Pulmonary Disease
(AECOPD) needs further elucidation. The aim of the present study was to evaluate the …

Background Respiratory viruses frequently are recovered in the upper-respiratory tract
during acute exacerbations of COPD (AECOPD), but their role as contributing pathogens …

Background Despite the increasing knowledge on the role of viruses in exacerbations of
COPD (AECOPD), it is less clear which viruses are involved and to what extent they …

Objectives We aimed to characterise and quantify the incidence of common infectious
agents in acute exacerbations of chronic obstructive pulmonary disease (COPD) requiring …
