Adding difficulty in the recluse diagnostic process is the obfuscation due to a large number of non-spider-related dermonecrotic lesions that physicians too often misdiagnose as recluse spider bites, muddling the medical literature and preventing proper treatment. Recluse antivenom is available in South America where envenomation manifestation appears more deleterious but not in North America where bites are less common and less dramatic. In contrast, recluse envenomations are not as easily recognized and remedied due to a wide range of manifestation of venom effects and a still-developing understanding of the pathophysiology. Widow antivenom has been effective in reversing envenomation symptoms within a short period of time. Widow envenomations are readily managed due to easily recognizable signs and symptoms the pathophysiology of the venom effects is well known. ![]() ![]() In North America, only the widow and recluse groups are considered to be medically important. ![]() Although there are many spider species throughout the world, most of which have venom, only about 60 are toxic enough to cause deleterious reactions in humans.
