just some "useless info" on scorpion bite that i thought you might find interesting.
south africa actually has a low incidence of scorpionism. unlike south west USA, mexico, india and north africa. there are worldwide roughly 100 000 cases of scorpionism per year resulting in 800 deaths. in south africa 95% of all cases of scorpionism result only in a mild local inflammatory reaction and pain lasting 15 min - 4 hours and no systemic effects. there are roughly 4 deaths per year. (nothing in comparison with cars, guns etc.)
the medically important scorpions belong to the family "buthidae". they are characterised by their thin pincers and broad tails. the other families "scorpionidae" are relatively harmless and are characterised by their large pincers and slender tails.
as far as the treatment of scorpion bites go, less that 5% of bites require medical treatment. scorpion first aid treatment entail cold compress, simple analgesics (paracetamol), cleaning of the wound. watch out for systemic symptoms.
antiserum is only recommend in patients with severe systemic symptoms (sweating, drooling, difficult swallowing, unable to stand, seizures, difficult breathing etc.) it should only be used by persons trained in the use of it as well as the management of allergic reactions. (must have adrenaline, steroids available)
i am of the opinion that it is unnecessary to carry scorpion antiserum with you since the incidence of "deadly bites" are low in SA. you can potentially do more harm than good. (especially in the wrong hands). it is a lot cheaper and safer to avoid bites - wear shoes, exercises caution when lifting rocks, don't sleep directly on the ground when camping, learn to distinguish between venomous and non-venomous scorpions.
