Unusual presentation of urban leptospirosis complicated by a septic shock

Leptospirosis, an infectious zoonosis, is common to tropical areas. The clinical presentation varies from flu-like symptoms to a serious presentation called Weil's syndrome. Fever and conjunctival suffusion are present in the majority of patients. This case report describes a resident of New York City who presented initially with gastroenteritis symptoms without fever or conjunctival suffusion to develop septic shock before being diagnosed with leptospirosis.
