It is possible that the child has papular urticaria, papular urticaria is formed mostly due to insects, such as mite allergies, mosquito bites and flea bites resulting in isolated, scattered, edematous papules. This papule sometimes manifests itself as red bumps due to inflammatory reactions, and the center of the bumps may form petechiae due to insect bites, and the petechiae may be unique; 2.
