As a rule, an allergy to flea bites in humans manifests itself in the form of a skin reaction, and the child’s body reacts more sharply than that of an adult. Flea bites itch and cause redness, dermatitis, or skin rashes. The sooner you can relieve the itching from flea bites, the less likely it is to introduce infections into the wound when scratching. Therefore, if you are bitten by a flea, the first thing you should do is treat the bite site with a soothing lotion or other remedy.
In this article, we will look at the types of allergies to flea bites in humans, symptoms and possible complications.
Types of allergies and their dangers
A person can develop an allergy to flea bites through contact with different types of parasites, for example:
- Sand fleas cause health damage. Their females are especially dangerous, as they penetrate under the top layer of the skin. The bites are painful even in the absence of allergies.
- The main victims of the human flea are people. These insects are larger than other representatives of the genus.
- Rat fleas are more dangerous than others. Their bites can cause not only allergies, but also other diseases: typhoid, plague, encephalitis. Allergic reactions to these insects are rare. Most of the cases are registered in villages, villages or among residents of the basement.
- Allergies to dog and cat parasites develop most often. To avoid illness, you need to put special collars on your pets or buy medications in the form of drops for treating fur.
Pathology can cause complications. Due to severe itching, a person begins to scratch the wounds. In this case, they can become infected. In addition, the lack of timely treatment sometimes leads to anaphylactic shock.
4.What to do after an insect bite?
If you are bitten by a bee on your hand, you should immediately remove all rings and other jewelry, and then try to pull out the sting. It is important to carefully remove the sac filled with poison using any hard object. At the same time, try not to pull the bag or press on it, as in this case you will only speed up the injection of the poisonous liquid.
People who are not prone to developing allergic reactions to wasp and bee stings should take a tablet of any antihistamine: Tavegil, Fenkarol, Parlazin, Suprastin, etc. It is also worth applying a lotion soaked in any antiseptic to the stung area, and then lubricate it with a soothing ointment. Act according to the circumstances. For example, if your hand is very swollen and the swelling does not disappear for a long period of time, apply a cold compress or ice to the affected area of skin. In such a situation, it would not be superfluous to take another antihistamine tablet.
It is important to monitor the condition of a person who has been bitten, as it can worsen at any time due to changes in blood pressure, an increase in body temperature, and the appearance of rashes on other areas of the skin. If necessary, you should call an ambulance.
What do flea bites look like?
Unlike mosquitoes and bedbugs, fleas do not inject painkillers into the wound when they bite. Because of this, a person immediately feels when he has been bitten by a parasite. Similar sensations occur with injections. Redness at the site of the bite appears within a few seconds. In its center, where the skin was bitten, there is a spot. Sometimes flea bites look like abscesses.
Redness at the site of the bite.
As the flea injects enzymes under the victim's skin, an immune response occurs. The bitten area swells and itching develops. Symptoms persist for a long time, even if you do not scratch the affected area. The wound heals within a few days. Sometimes suppuration is observed.
