Baby is allergic after mosquito bites

Although you can wear a lot of beautiful clothes in summer, there are still many things you need to pay attention to, such as mosquito bites. For adults, mosquito bites will at most cause red spots and itching, but for babies, mosquito bites are likely to cause potential viral damage. Babies have relatively weak resistance, and mosquito bites can easily cause allergies. Therefore, during daily care, you can spray some anti-mosquito floral water on your baby or wear an anti-mosquito bracelet. If allergies occur, they must be dealt with in time.

1: Cold compress can be used for mild symptoms

After being bitten by mosquitoes, most people experience temporary reactions at the bite site, such as mild redness, swelling and pain. In this case, if the skin is not infected, just rinse it with soap and water and apply ice compresses. It will usually get better after 30 to 60 minutes.

If small blisters appear locally, the swelling and pain may last for about 4 hours. Be careful not to break the blisters to avoid secondary infection. Bees often leave their stingers in the skin, which must be removed immediately, but be careful not to squeeze the area too hard to avoid spreading the venom.

2. Rub with garlic

Mosquito bites may cause allergic symptoms such as large redness and swelling. At this time, you can cut the garlic into slices and then apply it to the mosquito bite site. This can achieve a good analgesic, itching and anti-inflammatory effect. Even if the bitten area has become a large lump or inflamed and ulcerated, you can try rubbing it with garlic. Generally, the inflammation and swelling can be reduced after 12 hours.

3: Apply soap to relieve itching

When mosquitoes bite people, they secrete an organic acid - formic acid - from their mouthparts. This substance can cause muscle soreness and itching. Soap contains sodium salts of higher fatty acids. After hydrolysis, the sodium salts of these fatty acids will become alkaline, thus achieving the effect of eliminating pain and itching.

4: Apply detergent to reduce swelling

First wash the mosquito bite with clean water, but do not wipe it dry. Then you can use a wet finger to dip a little detergent and apply it to the mosquito bite. This can quickly relieve itching and the redness and swelling will disappear quickly. After the redness and swelling disappear, wash off the detergent on your body in time.

5: People with severe allergies can apply ointment

7% to 17% of people will experience enlarged erythema and swelling at the site of the bite. These may be larger than 10 cm in diameter and generally last for several days. In addition to local skin disinfection and cold compresses, you can also apply some hormone ointment and take some antihistamines orally, such as loratadine and cetirizine. Such patients will have the same reaction after being bitten again, and 3% to 10% of them will even suffer anaphylactic shock.

6: Diseases that may be caused by mosquito bites

1. Papular urticaria, also known as insect bite dermatitis

The insects that cause diseases are mainly arthropods such as fleas, mites, bedbugs, and lice. When the mosquito's proboscis pierces the skin, a stinging sensation will occur locally at first, followed by the appearance of red "lumps". Sometimes small blisters will appear in the center of the "lumps". The itching is very severe and will take many days to improve. After improvement, pigmentation will occur. This is the most typical insect bite dermatitis.

Children and women with delicate skin are the most susceptible groups. Severe patients may experience swelling and fever of one limb, and even local abscesses, fatigue, high fever and other systemic symptoms.

2. Paederus dermatitis

Paederus dermatitis is a black moth-like insect that will not actively bite people, but if it falls on the skin and is accidentally killed by slapping, it will secrete venom.

The venom stimulates the skin to form flaky red spots, most of which are covered with dense small pustules, and the patient feels local burning and pain. In severe cases, systemic symptoms such as fever, headache, dizziness, and swollen lymph nodes may also occur.

The above two diseases are skin diseases caused by direct stimulation of the skin by the secretions of the insect body after mosquito bites. In addition, the bites of insects such as bees, caterpillars, centipedes, scorpions, etc. can also cause redness, swelling and allergies of the skin.

7: The most common vector-borne diseases in my country

1. Forest encephalitis:

The main pathogenic insects are ticks, and the main symptoms are sudden high fever, headache, confusion, meningeal irritation signs, and paralysis. There are often sequelae and the mortality rate is high. It is a natural epidemic disease in forest areas, and the main epidemic area in my country is the Northeast.

2. Xinjiang hemorrhagic fever:

It is mainly distributed in deserts and pastures where hard ticks are active, with obvious regionality and seasonality. People are infected by the bite of an infected tick or through a skin wound. The onset is acute, with symptoms such as fever, headache, drowsiness, fatigue, vomiting, etc. In the later stage, there are bleeding spots on the skin and mucous membranes. Severe patients have epistaxis, hematemesis, hematuria, proteinuria and even shock.

3. Japanese encephalitis:

The main pathogenic insect in my country is Culex tritaeniorhynchus, which mainly causes viral encephalitis, with a high mortality rate and very serious sequelae. It is prevalent in both the north and the south, earlier in the south and later in the north.

4. Dengue fever:

The main pathogenic insects are Aedes aegypti and Aedes albopictus, which mainly cause high fever, rash all over the body, skin, mucous membranes and even gastrointestinal and intracranial hemorrhage. Patients with mild illness generally have a good prognosis, but patients with severe illness may also die. Mainly popular in Southeast Asia.

Malaria in my country is mainly caused by Plasmodium vivax and Plasmodium falciparum; it is an insect-borne infectious disease caused by infection with Plasmodium through the bite of Anopheles mosquitoes or transfusion of blood from people carrying Plasmodium. The main symptoms are periodic regular attacks, with chills, fever, and sweating all over the body. Long-term and multiple attacks can cause anemia and splenomegaly.
