Physical examination of SARS-CoV-2 infected Syrian hamsters (n = 3 per group). A Schematic diagram of SARS-CoV-2 infection and animal operations. Six-week-old male Syrian hamsters were intranasally inoculated with 1 × 10⁶ PFU SARS-CoV-2. Body weight and temperature were measured daily. Nasal lavage and necropsy were performed at each time point. Changes of (B) body weight, (C) body temperature, and (D) survival rate are shown. All data were presented as means ± SD.
