Leptospirosis is a zoonotic disease which is a public health problem in the tropics and subtropics. It is a disease with epidemic potential which has symptoms which can be confused with dengue, malaria or other vector-borne diseases, hence it sometimes underreported or misdiagnosed (CARPHA). Its symptoms may mimic many diseases, such as influenza, dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and laboratory) at the onset of symptoms is important to prevent severe cases and save lives, primarily in outbreak situations (PAHO). Symptoms include high fever, headache, chills, muscle aches, vomiting, jaundice (yellow skin and eyes), red eyes, abdominal pain, diarrhea and rash (CDC).
