Bites and stings from insects or animals can cause infection or poisoning from venom and proper first aid is important. Key priorities for any bite or sting include ensuring safety, removing the casualty from danger, treating wounds to prevent infection, and seeking medical help if needed. For animal bites, deep puncture wounds should be thoroughly cleaned and dressed until medical treatment can be received. Snake bites present additional dangers like breathing problems, and the wound should not be cut or sucked but immobilized until emergency assistance arrives. Insect stings may cause swelling, and a cold compress can help with pain while medical attention is sought for persistent or severe symptoms.
