THE EPIDEMIOLOGY OF SNAKE BITE IN CENTRAL PROVINCE AND NATIONAL CAPITAL DISTRICT, PAPUA-NEW-GUINEA

Snake bite is an important medical problem in some areas of Papua New Guinea and appears to be most common in the Central Province and Natio nal Capital District. The overall incidence for Central Province is 21 5 . 5 per 100 000 population, but Kairuku subprovince has an incidence of 526 per 100 000, which is amongst the highest in the world. The cl inical pattern of envenoming also varies within the Province, suggesti ng that different species of snake may be responsible for bites in dif ferent areas. Most envenomed patients are bitten during daylight on th e lower limb and are rarely able to describe the snake. The mortality rate in Central Province is 7 . 9 per 100 000; most patients die from ventilatory failure due to severe neurotoxicity. Mortality might be re duced by increased use of compression bandaging as a first aid measure , earlier treatment with antivenom and earlier referral to hospital.
