Mosquito and midge bites can cause a severe allergic reaction, inflammation or even infection. Midges often cause more trouble. This was reported to a journalist of UNN by dermatologist Valentina Torhan of the Odrex Medical House, who explained what to do in case of a bite.

What is the danger of midge and mosquito bites?

Dermatologist Torhan noted that at first glance, it is only itching and redness. But in some cases, insect bites can cause a severe allergic reaction, inflammation or even infection.

Midges often cause more trouble than mosquitoes: they literally gnaw a micro-wound in the skin, and their saliva provokes a strong inflammatory reaction - with pronounced swelling, itching, pain, redness, and sometimes suppuration. As for infections: mosquitoes in our region are not carriers of diseases such as malaria or West Nile fever (this is not endemic), but in Ukraine, there have been isolated cases of dirofilariasis - a parasitic infection that can be transmitted by mosquitoes

For which category of people can mosquito and midge bites be more dangerous?

Torhan listed the categories of people for whom bites can be more dangerous:

children - children's skin is more delicate, and the immune system may react more strongly;

allergy sufferers - especially those with a history of anaphylactic reactions;

people with immunodeficiency or chronic inflammatory skin diseases (atopic dermatitis, eczema) - a higher risk of infection after scratching the bite sites.

What not to do for mosquito and midge bites

Torhan stressed that the most important thing is not to scratch the bite site.

This significantly reduces the risk of complications. You should not "scratch" the bite site or make a so-called "cross" with your nails - this has no therapeutic effect, but significantly increases the risk of infection and can worsen the condition. You should also not use hot water on bite sites, as this can lead to increased itching and swelling
- the dermatologist noted.

Torhan advises washing the bite site with cool water and treating it with an antiseptic (e.g., chlorhexidine or octenidine) to reduce the risk of secondary bacterial infection. After antiseptic treatment, it is recommended to apply a remedy with anti-itching action - for example, a gel with dimethindene or diphenhydramine.

What to do when a person has scratched a mosquito bite very badly?

First, wash the skin with cool water and soap. Then, treat it with an antiseptic, and then apply a product that will reduce inflammation and protect the skin. It is good to have a cream or ointment with an antibiotic (you can also apply them cool - keep them in the refrigerator door). In case of severe swelling or severe itching, you can take an antihistamine (cetirizine, bilastine, or others according to age and indications). If suppuration occurs, the rash spreads, or the symptoms do not go away within a few days, you should consult a doctor for examination and treatment adjustment
