T63: Toxic effect of contact with venomous animals

The toxic effect of contact with venomous animals refers to a group of conditions that are caused by the transmission of venom from a variety of animals, usually through bites or stings. Such animals may include snakes, spiders, scorpions, and certain fish and insects. The venom, once introduced into the human body, can trigger a range of symptoms, which can vary in severity depending on the species of the animal and the individual's response. Common signs of venomous contact may include intense pain at the site of the wound, redness, swelling, and more systemic symptoms may include nausea, difficulty breathing, abnormal heart rhythms, and, in extreme cases, loss of consciousness. The progression of the disease largely depends on the type and quantity of venom introduced to the body, and the time that elapses before treatment is commenced. Typically, the integumentary system (skin and related tissues), nervous system, cardiovascular system, and respiratory system are impacted.
