Scratching is a normal phenomenon commonly seen in the people who are bitten by a mosquito. Itching is caused due to the allergic reaction caused by mosquito bite and to satisfy the urge of itching people starts scratching the site of the bite.

Symptoms Of Mosquito Bites
Different persons respond differently to the same mosquito bite. Some are highly sensitive while others are mildly or moderately sensitive. It has also been found that the people who are bitten by the mosquito multiple times are mildly affected while people with few times respond severely. This is the reason infants and children are extremely sensitive to a mosquito bite. The symptoms of mosquito bites include red bumps along with inflammation, swelling, and redness.

Allergic Reactions Of Mosquito Bites
As soon as the mosquito sits on your skin, it pricks your skin with the help of stylets consisting of a pair of maxillae and mandibles. The mosquito quickly starts the blood sucking process from the small vessels and during this process, the integrity of vessels gets destroyed resulting in their rupture. It is one of the reasons for redness and itching at the site of the bite. Our body has a mechanism that when the blood is exposed to the external environment, the process of blood clot starts and blood stops flowing. To counter this process, the saliva is injected into the human body by a mosquito with the help of a specialized structure called hypopharynx. The saliva of the mosquito contains anticoagulants, proteins, and at least 19 different enzymes. This varied amount of different chemicals triggers an immune response in the body leading to inflammation and itching at the site of the bite. It is interesting to note that only the female mosquito feeds on blood. Histamine is released in the body, by mast cells, leading o immunological response.
Recent research has indicated that there are chemicals, other than histamines, which are released by the mast cells. These chemicals carry the information from the site of a mosquito bite to the central nervous system, specifically to the brain, leading to the itching sensation.
Frequent and continuous scratching of the mosquito bite may lead to spread of symptoms, and exposure to the deep tissue that increases the risk of secondary infection.
