Papular urticaria is a type of allergic reaction associated with direct contact with irritants or bites from mosquitoes and fleas. Generally, this condition does not cause severe symptoms. Most commonly, it results in red papules and severe itching on the body, with occasional small blisters. If these blisters burst, disinfection with iodine can prevent infection. In some cases, if the blisters are large and burst, leading to infection, this may cause fever or other symptoms that require symptomatic treatment. It is advisable to frequently expose clothes, bedsheets, and covers to sunlight for disinfection, and to avoid keeping small animals at home or visiting areas with dense vegetation.
