Venom-induced consumption coagulopathy (VICC) is a medical condition caused by the effects of some snake and caterpillar venoms on the blood. [1] Important coagulation factors are activated by the specific serine proteases in the venom and as they become exhausted, coagulopathy develops. Symptoms are consistent with uncontrolled bleeding.
The studies found dry bite incidence of anywhere between 4% and 50%. [2] It is difficult to measure dry bite incidence rates because some "wet" (envenomed) bites may go unreported or result in minor or no symptoms, or the species of snake may be misidentified (for example, a bite from a non-venomous snake attributed to a venomous one). [2]
The US estimated annual count of animal bites is 250,000 human bites, 1 to 2 million dog bites, 400,000 cat bites, and 45,000 bites from snakes. Bites from skunks, horses, squirrels, rats, rabbits, pigs, and monkeys may be up to 1 percent of bite injuries. Pet ferrets attacks that were unprovoked have caused serious facial injuries.
When the snake bites, the salivary venom mixture is not injected, but it flows into the punctures produced by the upper jaw's rear teeth, which can penetrate the skin of humans. The venom from R. subminiatus has been responsible for internal hemorrhaging , including hemorrhaging of the brain, as well as nausea , coagulopathy , and even ...
Australian recommendations for snake bite treatment recommend against cleaning the wound. Traces of venom left on the skin/bandages from the strike can be used in combination with a snake bite identification kit to identify the species of snake. This speeds determination of which antivenom to administer in the emergency room. [55]
Additionally, snake and krait bites and envenomation cause significant morbidity; understanding the mechanism by which bungarotoxins work can improve treatment options in such situations. According to the World Health Organization , approximately 5.4 million people are bitten by snakes each year with 2.7 million people becoming envenomed. [ 7 ]

The bite is usually painless and difficult to see due to their small fangs. Human symptoms of a northern brown snake bite are headache, nausea/vomiting, abdominal pain, severe coagulopathy, and sometimes kidney damage. [7] In dogs and cats, paralysis is also likely to occur.
