Urticaria caused by mosquito bites

Because the weather is hot in summer, many adults will dress their babies in short-sleeved shirts and shorts to prevent them from getting prickly heat due to overheating. Although such clothing is cool, it is also easy to attract mosquito bites. Babies have relatively weak resistance, and mosquito bites may cause viral infections and cause urticaria. The main symptom of urticaria caused by mosquito bites is the appearance of large red bumps at the bitten site, and patients often scratch with their hands because they cannot bear the itching. When this happens, be sure to seek medical attention promptly.

The main manifestation of papular urticaria is the growth of red bumps of varying sizes that protrude above the skin on the areas where children are bitten by mosquitoes, such as the abdomen, lumbar region, buttocks, thighs, calves, etc. There may be as few as three or five, or as many as dozens, or even in groups; sometimes there are blisters in the center of the bumps, especially tension blisters on the hands and feet, which are prone to unbearable itching.

Characteristics of papular urticaria

1. Age: Most common in children.

2. Location: mostly located in exposed areas.

3. Skin lesions: Local redness and swelling, often spindle-shaped, with blisters and bullae on the surface, and bite marks sometimes visible in the center of the lesions.

4. Symptoms: obvious itching, which may be accompanied by tingling and burning pain.

5. Course of disease: Generally it will resolve on its own within 1 to 2 weeks. If secondary infection occurs, the course of disease will be prolonged.

6. Prognosis: First of all, the cause must be eliminated to avoid recurrence.

Treatment and prevention

1. Note:

Change and wash clothes and quilts frequently and dry them in the sun. When changing mats in hot weather, pay attention to insecticide, such as soaking sheets, quilt covers and mats in boiling water.

If you have pets at home, you must pay attention to hygiene and eliminate parasites in a timely manner, such as fleas, mites, bedbugs, etc.

For children who are prone to this disease, try to avoid playing in grass, shade, or humid places with many mosquitoes.

2. Topical medications: Generally, mild cases can be treated with medication to relieve itching, or with pure Chinese medicine.

3. Oral medication: If you have systemic symptoms, you can take the medication according to the doctor's instructions. If the condition is serious, you need to go to the hospital for treatment in time.

This disease is most common in children, especially those with allergic constitutions. However, the incidence rate of most children decreases with age, and even if it occurs, it is often mild. This is because repeated bites produce desensitization reactions.

It is particularly important to avoid excessive scratching, otherwise the condition will worsen and easily cause bacterial infection, becoming impetigo or causing other serious complications.

Parents are advised to pay attention that prevention of papular urticaria is better than cure. If there are more severe rashes and itching after the onset of the disease, you should seek medical attention in time and use oral and topical medications under the doctor's guidance.

Treatment and prevention:

1. The treatment of urticaria is first general treatment. It is best if the cause of urticaria can be found and eliminated. For example, if you know that you are allergic to a certain food, you will never eat it again; if you know that it is caused by physical factors, and urticaria occurs when exposed to cold air, you can try to avoid contact with cold air; for example, after some laboratory tests, it is found that the patient has a systemic disease, such as a thyroid abnormality, then you need to treat the primary disease.

2. In addition to general treatment, antihistamines are the first choice for treating urticaria. Traditionally there are first-generation antihistamines, such as chlorpheniramine and diphenhydramine. However, first-generation antihistamines generally have the side effect of drowsiness. In addition, some people feel thirsty and sleepy after taking them, which affects their use. The current first-line treatment for urticaria is second-generation non-drowsy antihistamines. There are many drugs in this category, such as loratadine, cetirizine, etc. However, it is best to use these drugs under the guidance of a doctor, because the duration of use and course of treatment are controlled by the doctor. Usually, acute urticaria can be cured within one or two weeks. However, chronic urticaria requires long-term medication, and some people may need to take it for 3-6 months.

prevention:

1: The characteristics of urticaria in children are: it is mostly caused by allergic reactions. The most common suspected causes are food first and infection second. The causes of urticaria vary depending on age and diet. For example, if infants are mainly fed with breast milk, milk, and dairy products, the causes of urticaria are mostly related to additives in milk and dairy products.

2: As they grow older, infants and young children begin to eat complementary foods. At this time, eggs, meat floss, fish floss, fruit juice, vegetables and fruits can all become causes of allergies. Preschool and school-age children often like to eat snacks, and there are more types of snacks and regular meals, so the chance of food allergies increases. Foods such as fruits, fish, crabs, shrimps, peanuts, eggs, strawberries, apples, plums, citrus, various cold drinks, beverages, chocolate, etc. may all be causes of allergies.

3: Children aged 2 to 7 lack self-control. When they go outdoors, in the wild, in the bushes, or under street lights in the evening, they are often easily bitten by insects, or come into contact with pollen, dust, mites, and the fur of pets such as cats and dogs, which can easily cause allergies, so prevention is necessary.

Treatment and prevention of baby nettle

1: Urticaria is a common disease in babies. There are many types and the causes are very complicated. Urticaria in children is often acute and initially presents with irritability and itchy skin. Soon wheals of varying sizes appear, which are light red or pale and irregular in shape. They quickly increase in size and number, merging into patches, accompanied by burning and stinging pain that come and go and disappear without leaving any trace after the symptoms subside. Because of the itch, the baby becomes irritable and scratches everywhere. The more it itches, the more he scratches, and the more he scratches, the more he scratches. If the digestive tract is affected, symptoms include vomiting, diarrhea, and abdominal pain; if the trachea and larynx are affected, shortness of breath and chest tightness may occur. When it occurs in loose tissue areas such as the eyelids, lips, and external genitalia, it manifests as localized edema.

2: When your baby develops urticaria, you should first find out the cause. It may be that the baby is allergic to foods such as fish, shrimp, eggs, and milk; it may also be an allergic reaction to penicillin, sulfa drugs, and preventive injections (vaccines); it may also be complicated by bacterial or viral infections and allergic reactions to pollen, dust, feathers, and insect bites; some urticaria is familial, and the baby has a hereditary allergic constitution. Parents should patiently find out the cause of urticaria under the guidance of a doctor, and stop taking or using drugs and foods that cause allergies.
