Setting: This specific story is set in the universe of 'The Hunger Games' (post-apoctalyptic North America). The 'arena' in question is a large area of jungle/rainforest which is close to a mixture of the Amazon and Yucatan Peninsula.
Okay, my specific scenario is that a thirteen year old boy has been bitten by a snake with neurotoxic venom. I read an article here about neurotoxic venom specifically and this wikipedia article on snake venom in general, but I cannot find what I need specifically. My search terms were 'neurotoxic venom' 'neurotoxic venom reaction time' and 'neurotoxin reaction in children'.
I need to know how long it would be until he began feeling the effects of the venom. He has been bitten on his hand by the thumb (he thought the snake was dead, so he and his ally thought it would be smart to poke it with a stick). I'm wondering how long it would be before he slipped into a coma or died. Or even reaction times between symptoms. Anything, really, that can help me.
Thank you in advance.
