Why does a mosquito appear as a red and swollen thing after biting a person

The unpleasant thing of being "bitten" by a mosquito should in fact be "stung by a mosquito". Mosquitoes can't open their mouths, so they won't bite on the **, it actually uses 6 needle-like structures to pierce people**, these short needles are the center of the mosquito's edible mouthparts. > these short needles suck human blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting, so that it can feast peacefully.

When the mosquitoes are full of food and drink and float away, all they leave behind is an itchy lump. >, however, the itchy sensation is not caused by a short needle pricking or chemicals in the saliva. We feel itchy because the body's immune system releases a protein called histamine to fight foreign substances, and this immune response triggers an allergic reaction at the bite site.

Histamine causes swelling of the tissues around the bite when blood flows to the bite site to speed up tissue recovery, and the intensity of this allergic reaction varies from person to person, with some people having a more severe allergic reaction to a mosquito bite. > only female mosquitoes bite mammals because they have to suck blood every three or four days to get the protein they need to make eggs; Male mosquitoes mainly feed on nectar, while female mosquitoes use animal body heat and physiological changes to search for targets, which may be why human ankles and feet are more commonly bitten by mosquitoes, because the blood vessels in these parts are closer to the body surface, so more body heat is released. > terms of mosquito species, there are more than 200 species of mosquitoes in the United States and more than 2,500 species worldwide.

In fact, in addition to Antarctica, mosquitoes can be seen everywhere, and they can also transmit diseases, such as malaria, yellow fever, encephalitis, and West Nile virus, etc., more than 700 million people are infected by mosquitoes every year After being bitten by mosquitoes, do not scratch and scratch, otherwise it is easy to cause bacterial infection. Experts recommend the following methods to relieve itching: 1

After being bitten by mosquitoes, ordinary people will have symptoms such as redness, swelling, itching, and pain, which can be relieved by alkaline substances, for example, ammonia can be used to relieve itching, or soap dipped in water can be applied to the red and swollen area, which can relieve itching within a few minutes. 2.If the bite is very itchy, you can flick it with your fingers first, and then apply flower water, wind oil essence, etc.

3.Apply or brew the itchy area with salt water, which will soften the bump and can also effectively relieve itching. 4.

The sap from the aloe vera leaf can be used to relieve itching. When it is red, swollen and itchy after being bitten by a mosquito, you can cut a small piece of aloe vera leaf, wash it and break it, and rub it a few times on the red and swollen area to reduce swelling and relieve itching.

Your condition is a symptom of being allergic to mosquito venom after being bitten by a mosquito. The white liquid that is squeezed out is the tissue fluid produced at the allergic site, not the venom of the mosquito.

Mosquitoes (arthropods, phylum, insects, Dipteras), mosquitoes).

Mosquitoes belong to the order Diptera, the family Culicidae, also known as "mosquitoes", and are the most important group of medical insects. Mosquitoes are widely distributed and have many species, so far the world has recorded a total of 3 subfamilies (Macropheles subfamily, Anopheles subfamily, Culex subfamily), 35 genera and 3600 species and subspecies. More than 370 species have been discovered in China, of which more than half are mosquito species of the three genera Anopheles, Culex mosquitoes and Aedes mosquitoes.

In fact, it should be said that it was stung by mosquitoes. Mosquitoes can't open their mouths, so they won't take a bite on the potato mold, it actually uses a six-branch needle-like structure to pierce people**, and these mouth-shaped needles (stylets) are destroyed into the center of the mouthparts.

These needles suck in blood in the same way that they draw blood; The mosquito also releases saliva containing anticoagulants to prevent blood from clotting, so it can feast peacefully. When the mosquitoes are full of food and drink and float away, what is left behind is a swollen bag that itches a few itches and relieves itching.

Because, there is a substance in mosquito saliva that has a vasodilating and anticoagulant effect, preventing blood from clotting, making it easier for blood to flow to the bite site.

But the itching sensation is not caused by mosquito stinging or chemicals in saliva, but by the body's immune system releasing histamine proteins to fight foreign substances. When blood flows to the bite site to speed up tissue recovery, histamine causes swelling of the tissues around the bite, which is an allergic reaction that is characterized by itching, swelling, and bunching.

Introduce several small methods, after being bitten by mosquitoes, can effectively reduce inflammation, swelling, and relieve itching:Once a person is bitten by a mosquito, the bite will appear red, swollen, pimples, causing local itching, especially for people with weak self-control (children, adolescents).Scratching hard often causes ulceration and infection.

Therefore, mosquito bites should be immediately anti-inflammatory, swelling, and itching.

1.Use a garlic stalk to break it open and rub the bite with a section to relieve itching and reduce swelling. Safe and non-toxic***.

2.Use dragon claw chrysanthemum, break a small fork and rub the bite bag with a section to reduce inflammation, swelling and itching. Safe and non-toxic***.

3.The effect of medicinal alcohol or iodine wine is good, safe and non-toxic***.

4.Apply with cool oil, wind oil essence or flower water, it has anti-inflammatory and anti-itching effects. Use with caution in case of allergic reactions.

5.Use salt water, toothpaste (preferably fruit-type), apply, safe and non-toxic***, also have anti-inflammatory, anti-swelling effects.

6.Smearing with dermatitis flat also has a good antiseptic and anti-itching effect, but due to the presence of hormones, ** allergies should be used with caution.

Prevent the exacerbation of the condition and the spread of the disease.

Mosquito bites react differently, and such reactions are quite normal.

Vampire mosquitoes generally include Anopheles mosquitoes, Aedes mosquitoes, and Culex mosquitoes.

Different mosquitoes react differently to bites. When a mosquito bites, it releases saliva containing anticoagulants to prevent blood clotting, and the body's immune system releases a protein called histamine to fight foreign substances, triggering an allergic reaction at the bite site.

When blood flows to the bite site to speed up tissue recovery, histamine causes swelling of the tissues around the bite, and the intensity of this allergic reaction varies from person to person, and some people have a more severe allergic reaction after being bitten by a mosquito.

Mosquito] is a family of insects under the order Diptera. Commonly known as mosquitoes or mosquitoes, this family of organisms is a small flying insect with stinging and sucking mouthparts. Usually females feed on blood, while males suck the sap of plants.

Introduction] It belongs to the family of insects of the order Diptera, and there are about 3000 species in the world. It is a small flying insect with stinging and sucking mouthparts. Usually females feed on blood, while males suck the sap of plants.

Blood-sucking female mosquitoes are intermediate hosts for other pathogens such as dengue, malaria, yellow fever, filariasis, Japanese encephalitis, etc. Mosquitoes are found on all continents except Antarctica. Among them, the genera Anopheles, Aedes and Culex are the most famous.

Morphology] Mosquitoes are small insects with a body length of about gray-brown, tan or black. It is divided into 3 parts: head, chest, and abdomen.

Species] Mosquito insecta, about 3,300 species and subspecies, 15 genera and 33 species and subspecies in China. The important vectors of mosquito-borne diseases are generally divided into three categories, one is Anopheles mosquitoes, one is Culex mosquitoes, and the other is Aedes mosquitoes.
