Five types of snake AVs are currently available: Bothrops AV (main one), Crotalus AV, Bothrops-Crotalus AV, Bothrops-Lachesis AV, and Micrurus AV... It is difficult for riverine and indigenous populations to reach health centers for treatment of venomous animal injuries... As a result, the number of cases detected officially is probably much lower than the real number... There is an urgent need to ensure availability of effective AVs and to improve their manufacture regulation... However, the possible interspecific venom variation associated with the geographical distribution of snakes may affect the effectiveness of therapeutic AVs against the Amazon Bothrops venom... Efficacy of Brazilian AVs against venom from some Amazon Bothrops species has been investigated... Experimental studies should indicate the need for inclusion of new venoms, the new product needs to be validated by clinical and epidemiological data; Perform stability studies of liquid AVs considering the Amazonian environmental conditions... Medical management of secondary infection, abscess, necrosis, and compartmental syndrome has been the subject of controversy, partly because of the lack of standardization regarding concepts and management protocols... The possibility of reducing local effects by means of drugs with anti-inflammatory activity, early antibiotic therapy for secondary infection, cross-neutralization of AVs for different types of accidents, and new complementary treatments need to be further investigated while observing good clinical practice and, preferably, in multicenter studies... There are no accurate predictive factors for side effects occurrence and preventing them is not always possible, even with the use of premedication containing corticosteroids and/or antihistamines... Existing studies do not include controls for the intervening variables and samples are of insufficient size, limiting the validity of the results... Recommendations: Establish partnerships for capture of Lachesis snakes and transport to vivariums of laboratories producing AVs; Guide Lachesis reproduction in captivity, which should be led by professionals familiar with their conditions both in nature and supportive maintenance environment; Follow shared Standard Operating Procedures (SOPs) for the collections of venomous animals in order to facilitate exchange of information.

Spatial distribution of snakebites and scorpion stings in the Brazilian Amazon in 2013.Maps were created using incidence per 100,000 inhabitants. A) Snakebites are largely distributed in the Amazonian states, with several counties presenting incidences higher than 100 cases per 100,000 inhabitants, especially in Northern Roraima, Eastern Pará, and Amapá, and in unevenly distributed municipalities across all states. B) Large scorpion sting hot spots are observed in the Western Pará state and Southeastern Amazonas. Several other counties present incidences higher than 100 cases per 100,000 inhabitants in the states of Mato Grosso, Tocantins, and Maranhão.

Several other counties present incidences higher than 100 cases per 100,000 inhabitants in the states of Mato Grosso, Tocantins, and Maranhão.

Mentions: In 2013, 27,181 and 78,091 cases of snakebites and scorpion stings were reported by the Brazilian Ministry of Health, respectively [4]. The highest incidence was in the North region (52.6 cases/100,000 inhabitants) followed by the Midwest (16.4/100,000). These values, expected to be higher in remote areas of the Brazilian Amazon [5], may be underestimated due to considerable underreporting. Fig 1 presents the spatial distribution of snakebites and scorpion stings in the Brazilian Amazon.
