There is a vital need for authentic COVID-19 animal models to enable the pre-clinical evaluation of candidate vaccines and therapeutics . Here we report a dose titration study of SARS-CoV-2 in the ferret model . After a high (5 × 106 pfu) and medium (5 × 104 pfu) dose of virus is delivered, intranasally, viral RNA shedding in the upper respiratory tract (URT) is observed in 6/6 animals, however, only 1/6 ferrets show similar signs after low dose (5 × 102 pfu) challenge . Following sequential culls pathological signs of mild multifocal bronchopneumonia in approximately 5-15% of the lung is seen on day 3, in high and medium dosed groups . Ferrets re-challenged, after virus shedding ceased, are fully protected from acute lung pathology . The endpoints of URT viral RNA replication & distinct lung pathology are observed most consistently in the high dose group . This ferret model of SARS-CoV-2 infection presents a mild clinical disease.
