The presence of ongoing alcoholism, particularly in patients with a history of heavy drinking, can increase the risk of aspiration pneumonia caused by *Klebsiella pneumoniae* due to compromised airway defences increasing the risk of inhaling contaminated oropharyngeal contents. Klebsiella pneumonia is often associated with more severe and necrotising lung infections.
