Epidemiological features as reflected by 101 patients with unequivocal sea-snake bite received in north-west Malaya are reviewed. Enhydrina schistosa caused over half the bites, including seven of the eight fatal bites. It is the most dangerous sea-snake to man. Over 90 per cent of the victims were male and 80 of the 101 patients were fishermen bitten at their job. Most victims were bitten on the lower limb through treading on the snake, and this resulted in more cases of serious poisoning than upper limb bites (caused through handling nets, sorting fish and so on). Only 14 cathers were bitten (through treading on the sea-snake; no bathers were bitten while swimming). In patients coming to hospital more than six hours after the bite, there was a four-fold increase in serious poisoning compared with patients coming within six hours of the bite. Thus, as time elapses after the bite, the victim is less likely to seek medical help unless poisoning is severe. Despite the lethal toxicity of sea-snake venom, in patients seen during 1957-61 before sea-snake antivenom became available, the mortality was only 10 per cent. Trivial or no poisoning followed in 80 per cent of the bites. On the other hand, of 11 patients (20 per cent) with serious poisoning, over half (six patients) died despite supportive hospital treatment. These epidemiological features observed in Malaya probably apply to most fishing folk along Asian coastlines where sea-snakes abound. If this is so, sea-snake bite must be a common hazard feared by millions of fishing folk, and a common cause of illness and death. But it is unlikely that the extent of this problem will be revealed to orthodox medicine for many decades because most fishing villages are far from medical centres; and even if hospitals or medical centres are available, fishing folk are usually reluctant to attend them. Only one species of sea-snake, Pelamis platurus, extends to the east coasts of Africa and west coasts of the tropical Americas, but for various reasons this species does not appear to constitute much of a hazard to fishing folk in these areas. Although bathers are occasionally bitten along Asian coasts, when they inadvertently tread on a sea-snake, the risk of sea-snake bite in this area is extremely low. The prevention of sea-snake bite and poisoning is considered. Highly effective antivenom is now available for treating victims with serious poisoning; death should not occur provided adequate medical treatment is given within a few hours of the bite. The main problem is provision of adequate medical care at rural medical centres and overcoming the reluctance fishing folk often have in attending these centres.
