Leptospirosis is a zoonotic disease with protean manifestations. A 35-year-old male presented with pneumonia after the Typhoon Morakot. Skin rash, conjunctival suffusion, and subconjunctival hemorrhage led us to the diagnosis of leptospirosis and the microscopic agglutination test confirmed the diagnosis. This patient well demonstrated the picture of conjunctival suffusion and reminded us of the alertness of leptospirosis after a typhoon.
