After being bitten by centipedes, patients may develop localized bleeding spots with redness, swelling, itching and pain, as well as systemic symptoms such as fever, chills, headache and nausea. Due to the different species of centipedes and the nature of venom released when biting the skin, their skin injuries may also vary. Generally, after biting, small bleeding spots can appear, and the venomous claws of centipedes can release venom after piercing into the skin thus causing inflammatory reaction of the skin, with symptoms such as redness and swelling of the surrounding skin accompanied by obvious itchiness and pain sensation. As the toxin spreads, the patient may experience systemic poisoning symptoms such as dizziness, nausea and vomiting, fever and chills, and even convulsions, which require medical attention as soon as possible. After being bitten by a centipede, you need to immediately flush the wound and surrounding skin with water and soapy water. Then consult a doctor promptly to avoid delaying the condition. After being sterilized by a doctor with iodophor, medications such as hydrocortisone ointment should be applied, and painkillers such as ibuprofen and acetaminophen can be used for patients with severe pain. It is recommended to choose relatively safe environments during field trips and to strengthen personal protection in dark and humid working environments in order to minimize centipede bites. If inadvertently bitten by a centipede it is recommended to go to the hospital in time to avoid adverse reactions.
