MRCP2-4197

A 35-year-old pregnant woman presents to the emergency department in a confused and agitated state after experiencing a seizure. She had woken up an hour earlier to find her husband dead in bed next to her, and an ultrasound confirmed that her 26-week-old fetus had also passed away. The patient reports that both she and her husband had been experiencing flu-like symptoms for the past week, and had recently moved into an old house they were renovating. The day before, they had painted their bedroom and eaten reheated Chinese food for dinner. The patient has a history of well-controlled asthma and had quit smoking when she became pregnant, but had recently been experiencing headaches. On examination, she is tachypneic with a respiratory rate of 24 breaths per minute, blood pressure of 90/60 mmHg, pulse of 120 beats per minute, and oxygen saturations of 98% on air. There is no visible rash or purpura on her body, and her heart and abdominal exams are normal. What is the most likely cause of this tragic event?
