A 6-year-old boy presents with a 3-day history of low-grade fever and abdominal pain. His mother reports that he has been less active than usual and refusing to eat. The abdominal pain is generalised but more pronounced in the right lower quadrant. He had a sore throat and a mild cough last week. On examination, he is febrile (38.2°C) with palpable tenderness in the right lower abdomen, but no rebound tenderness or guarding.

Which is the most likely diagnosis?
