Mosquitoes and bites: what happens to the skin?

In sensitized subjects, and in particular in allergic ones, the immune response can be important: in this case we speak of strophule, that is an erythematous-edematous reaction often with blistering and very itchy multiple lesions “explains the female doctor Claudia Casulli, dermatologist at the Santa Maria di Bari hospital.

“A different discourse, on the other hand, concerns the small children, struggling with the first bites: not yet sensitized, they have small papular reactions with little or no itching“.

They can be pharmaceutical or commercial preparations provided they contain toxic substances for mosquitoes, even of natural origin such as lemongrass, geranium or eucalyptus. Anti repellents must be sprayed on the most vascularized areas such as ankles, feet, back of the knees, elbows and wrists. Before leaving the house they must be sprayed on the skin and, to increase its effectiveness, even on clothing. In fact, mosquitoes are able to reach the epidermis also through the tissues.

“In particular, all those rich in vitamin Bsuch as meat, eggs and fish, and vitamin C then citrus fruits, peppers, kiwis and berries, in addition to green leafy vegetables. The same goes for supplements rich in both vitamins. Garlic should not be underestimated either“.

After the sting, to relieve itching and in some cases swelling, topical cortisone can be used several times a day of medium power, which can also be associated with topical or systemic antibiotics if inflammation occurs. «In children, creams based on ammonia or even zinc oxide can be useful, provided they are applied immediately. In case of severe itching, an antihistamine by mouth is recommended ».

AND, even for bites, the action of cold is important: keeping the cortisone creams in the refrigerator or making cold water compresses helps to relieve the discomfort. “On the other hand, I do not recommend natural remedies because they can cause photosensitivity, or reactions with exposure to the sun” concludes the expert.
