Why are cryptopters so poisonous?
Hu Jinjin, a master of dermatology and attending physician of the Third People's Hospital of Henan Province, introduced that cryptoptera secretes an acidic venom with an acidic value of 1-2 when crawling, while the pH value of sulfuric acid is generally between 0-1, "so the secretion of cryptoptera is very corrosive, it is not a bite." "So many people call cryptoptera: flying sulfuric acid."
What should I do if I have just been climbed over?
After understanding the origin of the toxicity of cryptoptera, Dr. Hu Jinjin reminded that when encountering cryptoptera, it is not possible to beat, and more acidic substances will flow out after the worm body ruptures, which can cause acute dermatitis, severe pain, and heavy body reactions. Patients with severe inflammation may be accompanied by systemic symptoms such as headache, dizziness, and fever, and superficial lymphadenopathy.
Once the skin is found crawling over by insects, it can be immediately scrubbed with soapy water and coated with 10% to 20% dilute ammonia solution (ammonia water) and 5% sodium bicarbonate solution. Timely use of alkaline drugs to neutralize the acidity of the venom.
What should I do if I find it late?
Hu Jinjin said that in the later stage of clinical treatment, wounds will be treated according to burns. If the skin is rotten, you can use potassium permanganate cold wet compress. If you have erythema on the skin, you can choose calamine lotion or glucocorticoid cream, such as deonide, fluocinolone ointment, etc. In severe cases, short-term oral corticosteroids may be given.

Many netizens said that "in the future, I will no longer dare to play with the mobile phone after turning off the lights at night." ”
