GPT and depressive symptom measurement: Specifically, Syrian hamsters infected with VSV-MARV/GP presented key symptoms, which are similar to MVD patients, including weight loss, depression, respiratory distress, and loss of exploratory behaviour; uniform mortality; multiorgan failure; and abnormal blood parameters, such as low WBC and PLT counts, elevated ALP and ALT levels, and high viral loads, suggesting systemic replication and hepatophilic effects of the virus, all of which have been observed in MVD patients and NHPs [23,44,50,51].
