Mr Patel is a 21-year-old gentleman who lives in a shared apartment with friends and studies English at a local college. He is from Bangladesh and shares an apartment with six adults, three adults in each bedroom. He was referred to the emergency department due to a 2-month history of a productive cough (no episodes of hemoptysis), associated fevers, drenching night sweats, loss of appetite and a 5-kg weight loss. In the last 7 days his symptoms have worsened and warranted this visit. Mr Patel has a pyrexia of 38.5deg C, he is cachectic and has pleuritic chest pain. His respiratory rate is slightly raised at 22 per minute and he has a tachycardia of 114 beats per minute. Blood pressure is normal. Inflammatory markers – erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) – are raised at 72 mm/h and 65.4 mg/L. A chest X-ray has been reported as abnormal with patchy shadowing seen in left upper lobe.
