The rapid and disorderly urbanization in the Amazon has resulted in the insertion of forest fragments into cities, causing the circulation of arboviruses, which can involve hematophagous arthropods and free-ranging birds in the transmission cycles in urban environments.

Birds were captured using mist nets, and hematophagous arthropods were collected using a human protected attraction technique and light traps.
