Chinese Moccasin which also goes by the name sharp-nosed viper or “100 Pacer” is one of the deadliest snakes in the world. It earns it’s “100 Pacer” nickname because you will probably be dead after 100 paces. They are native to southeast Asia and do not make good pets.
The snake’s venom is a potent hemotoxin that is strongly hemorrhagic. Symptoms of a bite include severe local pain and bleeding that may begin almost immediately. This is followed by considerable swelling, blistering, necrosis, and ulceration. Other symptoms, which often include heart palpitations, may occur suddenly and relatively soon after the bite.
Without medical treatment, bites are almost always fatal. The good news is there is an anti-venom, but it needs to be administered as soon as possible.
The Center for Wildlife Safety posted some photos from Vietnam on their Facebook page of what a bite can do in two hours.
The boy is lucky to be alive. Hopefully, he makes a speedy recovery.
