Partial Text: Most of the information regarding snakebites in the Brazilian Amazon is based on surveillance data or hospital medical records. Community surveys were conducted with forest-dwelling Indigenous people and rubber tappers (seringueiros) , and inhabitants of ten riverine communities . Snakebites predominate in adult males [7–12], strongly suggesting an occupational risk. People living in rural areas [8–11,13] and/or workers involved in farming, hunting, and forestry activities [6,7] were the most affected groups. Snakebite incidence correlated with the period of heaviest rainfalls [8,10–12]. Lower limbs were the most affected anatomical region. The time from the bite to the patient being seen at the hospital was usually longer than six hours [8,12,13]. Case fatality rates varied from 0.4% to 3.9% [6–8,10,11].
Despite important efforts carried out during the past decades in Brazil to understand and control the problem of snakebite and scorpion sting envenomings, important gaps remain for the fulfillment of these goals, particularly in the Amazon region. A workshop was held in Manaus, Amazonas, in 2013 with representatives of Health Departments of Amazonian states, AV producers, universities, reference hospitals, and the Ministry of Health to identify research bottlenecks. A proposal to create the research network Snakebite and Scorpionism Network in the Amazon (Rede de Ofidismo e Escorpionismo da Amazônia-ROdA) emerged from researchers at the Butantan Institute and the Tropical Medicine Foundation Dr. Heitor Vieira Dourado.
