The ferret model is a widely used animal model in biomedical research, particularly in the fields of influenza, respiratory syncytial virus (RSV), and other respiratory diseases. Ferrets are favored for this research due to their susceptibility to human strains of respiratory viruses and their anatomical and physiological similarities to humans. Researchers use ferrets to study the transmission, pathogenesis, and immune response to various respiratory viruses, as well as to test the efficacy of vaccines and antiviral drugs. Ferret models have been instrumental in advancing our understanding of respiratory diseases and have played a crucial role in the development of vaccines and treatments.
