Fever as a Sign of Leishmaniasis

Fever is a recognised clinical manifestation of Leishmaniasis. Leishmaniasis is caused by Leishmania protozoa transmitted by sandfly bites, presenting in visceral, cutaneous, or mucocutaneous forms. Visceral leishmaniasis (kala-azar) causes fever, splenomegaly, and pancytopaenia. Amphotericin B and miltefosine are first-line treatments.

  • ⚠️Fever in an immunocompromised patient

Diagnosis

Confirming Leishmaniasis as the cause:

  • • Clinical history and travel exposure assessment
  • • Blood count (eosinophilia is a key marker)
  • • Stool microscopy and parasite-specific PCR
  • • Serology (ELISA / IFA for antibodies)
  • • Imaging if tissue invasion suspected
