Russel's viper, hump nose viper (HNV), spectacled cobra and common krait were involved in 21 (23.1%), 14 (15.4%), 5 (5.5%) and 3 (3.3%) inflictions respectively. 77 (84.6%) victims were residents of rural area in opposition to 14 (15.4%) from urban area. 80 (87.9%) subjects presented with an alleged bite at lower extremities as opposed to 11 (12.1%) with infliction on upper extremities.
