The patient states she traveled to Australia about 3 weeks ago. Upon returning to the United States, she developed a persistent cough associated with dyspnea. She was seen by urgent care who diagnosed her with acute bronchitis and prescribed an inhaler. Over the following few weeks, her symptoms worsened, and she developed pleuritic chest pain.

Her vitals include a BP of 105/65 mmHg, HR of 120 beats per minute, RR of 24, temperature of 99*F, and an oxygen saturation of 94% on room air. Physical examination is noncontributory, except for rales in the left-mid lung. Her EKG reveals sinus tachycardia with large R waves in V1 to V3 and inverted T waves. Given this patient's history and presentation, what is the most likely etiology of her symptoms?
