A 2-year-old girl presented to the emergency department after a generalized tonic-clonic seizure that lasted one minute, an hour ago. She has been in good health since birth and has no history of convulsions in the past. She has been sick with an upper respiratory tract infection for the last 2 days, and her parents have been medicating her at home for a subjective fever. Her blood pressure is 109/51 mm Hg, pulse rate is 180/min, temperature is 38.9°C (102.0°F), and oxygen saturation is 98% on room air. The child is sleepy and ill-appearing. The cardiovascular, respiratory, and abdominal examinations are unremarkable. Blood glucose level is 50 mg/dL. Three boluses of IV dextrose are given, but the patient remains drowsy. CXR is normal. After a few hours, her clinical condition deteriorates with associated respiratory failure that requires intubation and mechanical ventilation. Liver function tests reveal AST > 3,000 U/L, ALT > 2,200 U/L, and INR > 3.0. Further testing ruled out hepatitis A, B, and C, and CMV infection. CT scan of the brain was normal. What is the most likely cause of her condition?
