• Abstract:

  The research proposes the construction of the Dengue Socio-Environmental Vulnerability Index (IVD) in the municipalities of the state of Pará, from 2007 to 2017. The study considered the selection of 34 indicators of the three fundamental components of socio-environmental vulnerability: exposure, sensitivity and capacity adaptive. The methodology for the IVD was composed of the steps:(i) selection of indicators;(ii) definition of indicators;(iii) statistical treatments;(iv) calculation of the index by multivariate analysis;(v) normalization; and (vi) classification of the index using the percentile technique. The results showed that 43 municipalities (30%) were classified as “Low vulnerability”, with values ranging from 0.483 to 0.262. Around 57 municipalities (40%) presented values with “Medium vulnerability” in the range of 0.581 to 0.483. With reference to “High vulnerability”, 43 municipalities (30%) stood out, distributed in the range of 0.771 to 0.582. The results obtained from the profile that characterized the IVD showed a predominance of “Medium to Low vulnerability”. The city of Belém, capital of Pará and located in the Guajará region, presented the lowest value for the IVD (0.262). On the other hand, most municipalities in the Marajó region presented the highest IVD values, namely: Cachoeira do Arari, Chaves, Ponta de Pedras, Melgaço, Santa Cruz do Arari and Anajás. The factor that most influenced the result of the index was the “socioeconomic” of the populations, especially the indicators of poverty, income, urbanization, illiteracy and solid waste management. It can be seen that the index is an important tool to assist in dengue prevention and control strategies in municipalities.
