Snake venom delivery system diagram

Envenomation is the process by which venom is injected into a victim by the bite or sting of a venomous animal. Venom is a complex mixture of proteins and enzymes that can cause a variety of toxic effects in humans and other animals. Envenomation can occur in a wide range of species, including snakes, spiders, scorpions, and marine animals such as jellyfish and cone snails.

Symptoms

The symptoms of envenomation can vary depending on the type of venom involved and the location of the bite or sting. Common symptoms include pain, swelling, redness, and bruising at the site of the bite or sting. In more severe cases, envenomation can lead to systemic effects such as nausea, vomiting, dizziness, difficulty breathing, and even death.

Treatment

The treatment of envenomation depends on the type of venom involved and the severity of the symptoms. In many cases, the first step is to clean the wound and apply a pressure bandage to slow the spread of venom through the lymphatic system. Antivenom, a specific antidote to the venom, may be administered in cases of severe envenomation.

Prevention

Preventing envenomation is key to avoiding the potentially serious consequences of venomous bites and stings. This can be achieved by wearing appropriate protective clothing, such as boots and gloves, when working in areas where venomous animals are present. It is also important to be aware of the types of venomous animals that are native to a particular area and to take precautions to avoid encounters with them.

Examples

Some common examples of envenomation include snakebites, spider bites, and scorpion stings. In each case, the specific symptoms and treatment options may vary, so it is important to seek medical attention promptly if envenomation is suspected.
