A 42-year-old woman presents with increasing fatigue and cough. She attributes it to the stress she experienced during a recent business trip to Italy. Since then, she has been feeling feverish and lethargic, and her cough started two days ago. She has no medical history but admits to having had unprotected sex recently. A chest x-ray reveals bi-basal consolidation, and her blood tests show the following results:

– White blood cell count: 12 * 10^9/l
– Hemoglobin: 135 g/l
– C-reactive protein: 145 mg/l
– Sodium: 125 mmol/l
– Potassium: 4.7 mmol/l
– Alanine transaminase: 87 IU/l
