Zou Yang, chief physician of Beijing Friendship Hospital and Beijing Institute of Tropical Medicine, said in an interview with the People's Daily health client on May 12, "Each segment of the body of the cryptoptera contains toxins, which is a strong acidic poisonous juice, which flies into the room at night and falls on the surface of the human body to secrete poisonous juice, or the insect body is broken and releases venom, which can cause dermatitis within 2-4 hours, also known as cryptoptera dermatitis." ”①
According to Dr. Zou Yang, dermatitis caused by cryptoptera has obvious seasonality, which generally begins to appear in June, with the peak of incidence from August to September, and gradually decreases after October.

Dr. Zou Yang said, "If you accidentally come into contact with the body fluids of Cryptoptera, you should wash the damaged skin repeatedly with soap and wipe the damaged skin repeatedly with 4% soda solution or 10% ammonia to neutralize the toxins. After the appearance of herpes, analgesia and itching, anti-inflammatory and astringent drugs are used to reduce irritation, and severe cases should be treated in the dermatology department of the hospital in time. ”①
