If a domesticated lizard bites someone, it is recommended to immediately disinfect the wound and inject tetanus shots if necessary to prevent infection. After being bitten by a domesticated lizard, immediately flush the wound with a large amount of water or soapy water, keep squeezing the bleeding to detoxify the wound, and then disinfect it with iodine vapour or alcohol, and if there is a wound or bleeding, it is recommended to promptly inject tetanus antitoxin or tetanus immunoglobulin within 24 hours. Tetanus is caused by tetanus bacillus that invades and infects through broken skin. This bacterium belongs to anaerobic bacteria and is easily infected through broken wounds. When the wound is healing, don’t let the wound get wet to avoid infection, don’t eat spicy and stimulating food, don’t drink alcohol, and avoid strenuous exercise in the short term.
