ResumoTo evaluate: (1) the occurrence, maintenance, productivity, spatial distribution and premise condition index score of Adese aegypti-infested houses and key-premises in a suburban district (Tubiacanga) and a slum (Favela do Amorim) of Rio de Janeiro and (2) the role of these factors in adult Ae. aegypti female spatial distribution. Methods and ResultsA total of 2456 premises were inspected for immature and 1100 for adult collection. Key-premises corresponded to 16.08% and 17.86% of infested houses in Tubiacanga, and 13.5% and 11.1% in Favela do Amorim, during the dry and wet seasons, respectively. Key-premises held significantly more immature Ae. aegypti, pupae and larvae than infested houses in Favela do Amorim and Tubiacanga during the dry and wet seasons. In Favela do Amorim, key-premises had a significantly higher PCI score than infested but non-key houses. ConclusionThe spatial distribution of key-premises and adult Ae. aegypti females was often congruent, indicating that key-premises influence the infestation pattern observed in the study areas.
