Papular urticaria is a type of allergic reaction, mostly related to contact with irritants, or bites from mosquitoes and fleas, and also has a certain relationship with one's physical constitution. Therefore, there is no permanent cure for this condition; it can only be completely treated with appropriate medication during a flare-up. However, exposure to allergens could lead to recurrence, and the condition has a distinct seasonality, usually peaking in summer and less common in winter. At home, it is advisable to avoid keeping small animals. If there are small animals, they should be bathed and disinfected frequently. Try to avoid going to places with lots of flowers, trees, or insects, and ensure bedding such as sheets and duvet covers are frequently exposed to sunlight for disinfection. During treatment, it is crucial to bathe frequently and maintain personal hygiene.
