Influenza A of human, swine, equine and avian origin: comparison of survival in aerosol form.

Abstract

Strains of Influenza A representative of human, avian, swine and equine sources were examined for decay when in aerosol form. Strains having their origin in avian and equine hosts were considerably more resistant to decay. Strains derived from human and swine sources were less resistant and bore a similarity in this property.
