1. A 25-year-old female gives a history of a high-grade fever with chills for the past 2 weeks, and diarrhoea over the past 10 days. She is a resident of a working womenÂ’s hostel and complains that several of her colleagues have also been unwell. She also complains of a dragging sensation in the upper left abdomen that is relieved by rest. On examination, she is dehydrated and febrile. Abdominal examination reveals the presence of a firm splenomegaly, almost reaching the umbilicus.
