Papular urticaria is a type of allergic disease, mostly related to exposure to irritants, or bites from mosquitoes and fleas. This disease is not contagious, and it cannot be transmitted through contact with others.

Once the disease is discovered, it must be treated with proper anti-allergy medications. Additionally, it's important to frequently sun-dry and disinfect personal items such as bed sheets, duvet covers, and clothes. Avoid keeping small animals at home and try to stay away from areas with lots of plants and trees.

Some cases of papular urticaria may develop small blisters. These blisters should not be punctured as breaking them can lead to infections and potentially more severe symptoms. Generally, with proper treatment, the symptoms can gradually subside, usually within about a week.
