This is a paper about common sense and respiratory disease using information that has been known for some time i.e. historical, and which is not accessed when a literary search is supplied by a computer. Respiratory disease in pigs has its most serious effects in the finishing stages, when the sequelae to progressive atrophic rhinitis, enzootic pneumonia and Actinobacillosis are most severe. Nowadays this relatively simple position is even more complicated by the worldwide occurrence of porcine reproductive and respiratory syndrome (PRRS) and porcine circovirus type 2 (PCV-2)-associated diseases principally PMWS where no vaccination is practised. Up to 80% of lungs may show the lesions of enzootic pneumonia, 20% may show the lesions of acute or chronic pleurisy, and up to 20% of the pigs may have snout lesions due to progressive atrophic rhinitis.
