By the night of transfer he was noted to have opisthotonic posturing and to have developed increasing respiratory distress and unresponsiveness. On examination, he had a temperature of 41.7°C rectally, a blood pressure of 70/30 mmHg, a heart rate of 110 beats/min, and a respiratory rate of 40/min. Examination was notable for marked trismus.
