How Do Mosquito Bites Turn Red?

Getting bitten by mosquitoes can be a pain. They can carry germs that can cause diseases. Depending on the type of bite, you can have a variety of symptoms. The most common are swelling, itching, and redness.

When a mosquito bites your skin, the chemicals in the saliva of the mosquito will stimulate your body to produce histamines, which causes the swelling and itching. Some people are allergic to mosquito saliva, and the swelling can be severe.

There are many different types of reactions to a mosquito bite. The most common reaction is a small, itchy red bump that appears within hours to days after the bite. Some people develop a systemic allergic reaction, which is a more serious reaction. This can occur if you are suffering from an allergy or if you have a preexisting immune deficiency.

Another reaction to a mosquito bite is a bacterial infection called cellulitis. The infection can spread into the skin and cause a deep, painful, or even life-threatening reaction.

A person who has a bacterial infection may experience fever, sweating, and difficulty moving. If the infection is severe, seek medical attention immediately. If you have a recurring itch or a fever, you should try to avoid mosquitoes.

A bite from a female mosquito will generally not hurt, but it can cause some irritation. The insect is attracted to heat and light, and it uses a proboscis, or long, flexible tube, from its head to pierce your skin.
