MISE, Yukari Figueroa; LIRA-DA-SILVA, Rejâne Maria  y  CARVALHO, Fernando Martins. Envenomation by Bothrops in the State of Bahia: epidemiological and clinical aspects. Rev. Soc. Bras. Med. Trop. [online]. 2007, vol.40, n.5, pp.569-573. ISSN 0037-8682.

This study describes the clinical and epidemiological characteristics of 655 cases of Bothrops snakebites that were attended by and/or notified to the Bahia Antivenin Information Center, State of Bahia, Brazil, in 2001. The annual incidence in the State was 5.0 cases/100,000 inhabitants and lethality was 1%. The incidence was greatest in the North Coast microregion (21.9/100,000 inhabitants) and the municipality of Itanagra (92.9/100,000 inhabitants). The snakebites occurred predominantly during the day, affecting the lower limbs of men aged 11-30 years who worked in rural areas during the rainy period. Medical care was obtained more than 13 hours after the snakebite in 19% of the cases. Moderate (47.8%) and severe (23.6%) clinical presentations prevailed. The local and systemic clinical manifestations followed the usual pattern for Bothrops snakebites in Brazil. However, a few cases presented neurological manifestations, which are not usually attributed to Bothrops snakebites. The antivenin therapy used (7.7 blisters/patient) reflected the fact that the majority of the cases were moderate. Antivenins other than the univalent type were used in 2.3% of the cases.
