What Are the Differences Between Hives and Mosquito Bites?

Urticaria, also known as hives, is a manifestation of limited edema caused by dilation of small blood vessels in the skin and mucosa and increased permeability. It usually recurs repeatedly until the allergen is isolated and gradually improves. Mosquito bites can also cause skin itching similar to urticaria. Many people do not know the difference between urticaria and mosquito bites. What are the differences between urticaria and mosquito bites? Let's take a look at it.

Urticaria usually appears as a patch, while mosquito bites usually occur in one or two places. Mosquito bites usually resolve automatically after a certain period of time, while urticaria does not. Urticaria is generally easy to identify, with swollen areas that are white in the middle and red at the edges, and usually itchy. Urticaria mostly occurs in children and young adults.

Urticaria, commonly known as hives, is a localized edematous reaction caused by dilation of small blood vessels in the skin and mucosa and increased permeability. It usually resolves within 2 to 24 hours but new rashes can recur repeatedly. The course of the disease can last from several days to several months and is clinically common.

The causes of urticaria are very complex, and about 3/4 of patients cannot find the cause, especially in chronic urticaria. Common causes mainly include: 1. Food and food additives; 2. Medications; 3. Physical factors such as mechanical stimulation, temperature changes, and sunlight; 4. Insect bites; 5. Mental factors and endocrine changes; 6. Genetic factors, etc.

Developing good habits, eating a balanced diet, exercising moderately, and improving immunity can help prevent urticaria. Avoid factors that can trigger the disease, such as extreme cold or heat, sun exposure, friction and pressure, and stress. Actively treating related systemic diseases can also help prevent the occurrence of urticaria.
