What should I do if I am bitten by a mosquito and my body is covered in bags?

Almost everyone has the unpleasant feeling of being "bitten" by mosquitoes, in fact, it should be said that they are "stung" by mosquitoes. 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. In 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 mosquitoes, you can cut a small piece of aloe vera leaf, wash it and break it, and rub it on the red and swollen area a few times to reduce swelling and relieve itching.

Just feed a spider and catch mosquitoes.

There is usually soap or soap in the home, and we can apply soap or soap dipped in water to the area bitten by mosquitoes. The reason why this soap or soap can relieve pain and itching is because of the sodium salt of the soap's higher fatty acids. The sodium salt of this fatty acid is alkaline (containing OH-) after hydrolysis, and the aqueous solution of formic acid contains H+, because the OH- in the soapy water is neutralized with the H+ of formic acid to form H2O, which can have the effect of eliminating itching.

You can apply salt water or soak your itchy area, which can soften the bump and can also effectively relieve the itch. I heard that salt water can relieve itching before, but then I tried it myself and found that it is okay, using aloe vera leaves to relieve itching, we can tear a small piece of aloe vera leaves and rub them on the itchy area. It can also have an anti-itching effect.

There is also a pill of antihistamine medicine, which has a preventive effect, but it is not recommended for everyone to take it, because generally similar to this drug has a certain amount of ***, and there is a feeling of sleepiness after eating.

What happens after being bitten?

After being bitten by mosquitoes, you can use soap or baking soda to dilute and locally neutralize the mosquito acid toxin to reduce redness and swelling, and at the same time, you should also consider relieving itching, you can use green ointment, flower water, no-pole ointment, calamine lotion, etc., to scrub the bite site. If the infection is complicated, an antibiotic, such as erythromycin, can be applied to the bite.

If it's a normal mosquito bite rash, you can follow this four-step approach:

1. Apply with alkaline solution. For example, soapy water, soapy water and other detergent solutions.

As we all know, the rash after mosquito bites is caused by the mosquito's acidic saliva entering the mosquito and causing the immune inflammatory response within the mosquito, so when you find the rash that has just bitten, apply it with an alkaline solution to neutralize the acidic mosquito saliva and reduce the inflammatory reaction. If you can get medical dilute ammonia, it is also good to apply it externally.

2. Weak and moderate hormone ointment. Such as mometasone furoate cream, hydrocortisone ointment.

If the ordinary anti-itching measures are not effective, it may be caused by a heavy inflammatory reaction. At this time, you can use hormone ointment containing weak or moderate potency for external use, such as mometasone furoate cream, hydrocortisone ointment, etc., to reduce inflammation. Many patients have concerns about using hormonal ointments, but short-term, small-area medium-low hormone ointments are safe.

Hormones are the most effective anti-inflammatory drugs, which can quickly relieve itching, which can avoid further scratching caused by ** ulceration, scabbing and other reactions, so reasonable use is more beneficial than disadvantageous. Of course, if there is already a break caused by scratching at this time, the hormone ointment should try to avoid the broken area and apply it to the unbroken area.

3. Oral antihistamines to relieve itching. Such as cetirizine hydrochloride tablets and loratadine tablets.

If the mosquito bite area is large and the number of rashes is large, topical drugs alone may not be able to relieve the itching. At this time, some antihistamines can be taken orally for a short time to relieve itching. These drugs are commonly used as cetirizine hydrochloride tablets, loratadine tablets and other drugs.

4. Pay attention to sunscreen in the bite part, and the damaged ** is easy to leave pigmentation.

The last step is probably the most overlooked: protect mosquito bites from the sun as much as possible, especially if the inflammation is very heavy or if the scratch is broken.

In fact, the rash of mosquito bites will slowly subside over time, but many people are left with unsightly pigmentation after it subsides. Such pigmentation can take months or even years to subside. As everyone knows, the formation of these pigmentations is related to the degree of inflammation on the one hand, and to sun exposure, that is, ultraviolet exposure, on the other hand.
