BACKGROUND
The outbreak of sylvatic Yellow Fever (SYF) in humans during 2016-2017 in Brazil is one of the greatest in the history of the disease. The occurrence of the disease in areas with low vaccination coverage favoured the dissemination of the disease; therefore, it is necessary to identify the areas vulnerability to the YF virus (YFV) to assist in the adoption of preventive measures.
OBJECTIVE
To correlate the physical-environmental elements associated with the occurrence of SYF in humans via a multicriteria analysis.
METHODS
For the multicriteria analysis, preponderant elements related to SYF occurrences, including soil usage and coverage, temperature, precipitation, altitude, mosquito transmitters, and non-human primate occurrence areas, were considered. The results were validated by assessing the correlation between the incidence of SYF and the vulnerable areas identified in the multicriteria analysis.
RESULTS
Two regions with different vulnerability to the occurrence of the disease were identified in the multicriteria analysis, with emphasis on the southern areas of the state of São Paulo northeast areas of Minas Gerais, and the entire states of Rio de Janeiro and Espírito Santo. The map of SYF vulnerability obtained in the multicriteria analysis coincides with the areas in which cases of the disease have been recorded. The regions that presented the greatest suitability were in fact the municipalities with the highest incidence.
MAIN CONCLUSIONS
The multicriteria analysis revealed that the elements that were used are suited for and consistent in the prediction of the areas that are vulnerable to SYF. The results obtained indicate the proximity of the areas that are most vulnerable to the disease to densely populated areas where an

infestation was observed, which confers a high risk of re-urbanisation of YF.

O presente trabalho analisou o conteúdo dos Planos de Ação Emergencial (PAE), documento exigido pela Lei Federal nº 12.334/10, a Política Nacional de Segurança de Barragens, das barragens de alto Dano Potencial Associado (DPA) instaladas município de Ouro Preto, MG. Para tanto utilizou-se o como método de estudo a análise de conteúdo documental dos PAE arquivados nos órgãos responsáveis. Após acesso aos PAEs, verificou-se na época que das onze barragens de DPA instaladas em Ouro Preto, apenas sete possuíam planos protocolizados na Defesa Civil do município. Ao se analisar o conteúdo dos Planos (PAE), viu-se que, de modo geral, todos apresentam os itens mínimos exigidos por lei, mas a maioria deles apresenta estudo deficiente de cenários hipotéticos em eventual ruptura da estrutura de contenção, problema que que se espera ser melhor estudado com o lançamento da Portaria DNPM nº 70.389 de 2017. Por fim, viu-se que após grandes desastres como o da barragem de Fundão da Samarco Mineração, há uma tendência de maior concretização, valorização e efetivação do PAE como principal instrumento para adoção de medidas emergenciais por parte dos proprietários de barragens em eventuais situações de risco e desastres.
