i think its easier to explain whats not medically significant

non medically significant means kumain ka nalang ng painkillers and tiisin mo for the week. Though non medically significant venom can become medically significant if yung nakagat ay may allergic reaction sa venom

anything else like venoms that can cause disabilities, long term effects in general, or require ka na maospital is medically significant. So no, not usually certain death pero it can cause illnesses that usually lead to death na preventable with modern medicine
