Hepatitis A Virus (HAV) infection is a benign, self-limited gastrointestinal infection of children. Autoimmune hematological manifestation is very rare in children. Here, we report an 11-year-old male child having HAV infection with acute liver failure, complicated with persistent thrombocytopenia and haematuria during the course of illness and eventually diagnosed as a case of HAV infection associated with immune thrombocytopenic purpura. The child was treated successfully with a short course of steroid therapy.
