Papular urticaria is a type of contact allergic reaction, related to contact with irritants or bites from mosquitoes and fleas. Generally, this disease can gradually subside on its own within about a week to ten days without treatment. However, some patients experience severe itching after infection, and scratching may lead to the formation of small blisters and secondary infections in the affected area. Therefore, once infected with this disease, it is essential to undergo standardized treatment. Treatment may include oral and topical anti-allergy medications, which typically can cure the condition within about a week. After recovery, it is also important to prevent recurrence by avoiding areas with many mosquitoes, not keeping small animals at home, frequently sunning and disinfecting clothes, bed sheets, and duvet covers, and bathing regularly.
