The following parameters were recorded on admission: age, sex, stage of COPD (according to GOLD criteria), smoking habits and alcohol addiction, use of oxygen, influenza vaccination, comorbidities (confirmed by medical records), current medication as well as signs and symptoms of respiratory tract infection. In this study we found: a) a high frequency of AECOPD due to viral infections in elderly and non-elderly patients without differences between the two groups, b) more frequent infections due to human Parainfluenza virus (hPIV) and influenza in elderly patients compared to non-elderly longer and c) lengthier hospital stays for the elderly patients. We didn't find any difference in the mortality in elderly AECOPD patients with a viral infection compared to the non-elderly although mortality is higher in COPD patients with lung cancer, pulmonary heart disease, heart failure, atrial fibrillation, obstructive sleep apnea, obesity, osteoporosis and asthma [24] .	./cache/cord-337431-3rrvm787.txt	./txt/cord-337431-3rrvm787.txt
