to sum it up: - environmental source (residence hall) - no person to person transmission - SUPERIMPOSED pneumonia, NOT a COPD exacerbation + common bacteria for superimposed - H. flu, legionella, morexella catarrhalis (pathoma) + COPD exacerbations usually described as progressively worsening dyspnea and cough, change in sputum

+1/- lynn(16)

formatting got messed up and now its unreadable - lets try again

legionella because it's an environmental source (residence hall), no person to person transmission, SUPERIMPOSED pneumonia (NOT a COPD exacerbation)

common bacteria for superimposed - H. flu, legionella, morexella catarrhalis (pathoma)

COPD exacerbations usually described as progressively worsening dyspnea and cough, change in sputum; more often viral than bacterial/fungal (UW)
