A mosquito bit you. What could be more mundane during this season. But instead of a little itchy pimple, you have a surprising allergic reaction. Redness, heat, and sometimes other symptoms that are more annoying for your health. Wouldn’t you have Skeeter syndrome?
What is “Skeeter syndrome”?
Skeeter syndrome is an exacerbated allergic reaction to proteins contained in mosquito saliva. When it stings, the insect injects, via its proboscis, anticoagulant and anesthetic substances. It is this saliva that our body can identify as a threat. In response, the immune system releases histamine, which leads to inflammation.
For some people, this response is excessive. Dr. Gérald Kierzek, emergency physician, specifies:
“Unlike a simple sting, which causes local redness and itching, Skeeter syndrome triggers an intense, sometimes worrying, inflammatory reaction.”
How to recognize a reaction linked to Skeeter syndrome?
Certain signs should put you on the track. A few hours to a few days after the bite, we can observe:
- A significant swelling (often greater than 5 cm), hot and painful;
- Intense redness, accompanied by a feeling of heat;
- Very strong itching, sometimes comparable to a burn;
- The possible appearance of blisters, or even hard edema under the skin.
In the most severe cases, the person may also present with a fever, unusual fatigue, or even swollen lymph nodes. In children, who are more sensitive, these reactions can last several days. Note that these reactions most often occur in people who are already sensitive to insect bites, or whose immune system is weakened (fatigue, illness, stress, etc.).
When should you worry about a mosquito bite?
The majority of cases of Skeeter syndrome remain mild, although uncomfortable. However, certain symptoms require rapid consultation or even urgent treatment.
According to our expert, see a doctor if:
- The swelling extends beyond the stung area or persists for more than 48 hours;
- The sting becomes very painful, pulses or suppurates;
- A moderate to high fever appears, accompanied by body aches;
- A child has an unusual or lasting reaction.
On the other hand, call 15 urgently if you observe:
- Breathing difficulties.
- Swelling of the face, lips or tongue (risk of anaphylactic shock)
- Vomiting, malaise, or a flu-like illness, especially in tropical areas (risk of vector-borne diseases such as malaria or dengue fever).
Good reflexes to prevent or relieve Skeeter syndrome
Even if you cannot completely avoid mosquitoes, certain precautions can limit the risk of a severe reaction:
To prevent bites, the rules are known:
- Wear long, covering clothes, especially in the evening;
- Use suitable repellents, especially in tropical areas;
- Install mosquito nets on windows and around the bed
In the event of a sting, our expert offers shock treatment:
Wash the affected area thoroughly with mild soap and water. Then apply an ice pack, wrapped in a clean cloth, for about 10 minutes. To relieve discomfort, you can use a soothing cream, preferably based on mild corticosteroids (such as hydrocortisone 1%, on medical prescription). If there is severe itching, taking an oral antihistamine, such as cetirizine, may be beneficial.
Finally, easier said than done, but absolutely avoid scratching: this increases the risk of infection, concludes our expert.
