Abstract

Chickenpox is an acute disease caused by the varicella-zoster virus (VZV), a herpesvirus that causes human infection worldwide. Primary VZV infection routinely occurs during childhood and is usually a self-limiting illness in immunocompetent children. However, chickenpox can be a severe disease in adolescents, adults, and immunosuppressed or immunocompromised patients. Although vaccination substantially attenuates disease manifestations, significant complications such as secondary soft tissue infection, encephalitis, and pneumonia can occur. We present a rare autopsy case of concurrent acute myocarditis and intussusceptions in a 3-year-old female child who presented with chickenpox followed by abdominal pain and sudden death. The present case emphasizes the potential for fatal complications of viral infections, which should be considered in cases of sudden unexpected infectious death in children.
