The vector infestation of the A. aegypti mosquito was estimated from the Building Infestation Index (BII), which assesses the risk situation of arbovirus transmission by measuring the population level of the vector when calculating the percentage of properties with the presence of larvae of this Culicidae within the total number of surveyed properties24
. The calculation is performed using the Rapid Index Survey for A. aegypti (Levantamento Rápido de Índices para A. aegypti – LIRAa) and the BII is classified as: satisfactory (<1%), alert (1–3.9%), and at risk (>3.9%)24
. These data were provided by the Environmental Surveillance of 1st GERES/SES-PE.
