Myocarditis presenting with pyrexia of unknown origin (PUO) indicates either a viral etiology or bacterial infection with endotoxin production. Rickettsial fever presenting as myocarditis leading to cardiac failure is rare. A three years old boy presented with high grade fever for 3 weeks, cardiac failure secondary to myocarditis, pallor and hepatosplenomegaly. Weil Felix test was positive with OX 19 and OX 2 > 1:320 suggestive of Indian Tick Typhus. The child responded to doxycycline. Thus, rickettsial fever needs to be considered in the differential diagnoses of PUO with myocarditis.
