Estudo de impacto de influenza aviária em Dois Vizinhos: delimitação de áreas de risco com geoprocessamento

Abstract

Avian influenza represents a significant threat to global poultry farming, with devastating economic impacts and risks to public health, as it is a zoonosis that can be transmitted to humans. This work aims to evaluate the potential health impacts of avian influenza in the municipality of Dois Vizinhos, Paraná, one of the largest poultry hubs in the state. Google Earth Pro was used to map poultry properties, identifying 465 poultry farms in the municipality. The area was subdivided into four zones (A1, A2, A3, A4) to facilitate the analysis of poultry density and the simulation of avian influenza outbreaks. The study followed the guidelines of the National Contingency Plan for Avian Influenza and Newcastle Disease, establishing protection zones (3 km radius) and surveillance (7 km radius) from hypothetical outbreak foci. The analysis revealed that the area with the highest concentration of poultry farms was the outbreak protection zone 3, with 73 poultry farms in the protection zone and 227 in the surveillance zone, totaling 300 poultry farms at risk. The results highlight the vulnerability of regions with a high density of poultry farms to health outbreaks, highlighting the need for strict preventive measures. The study reinforces the importance of biosecurity and continuous monitoring to guarantee public health and the economic sustainability of local poultry farming.
