Why this research matters now
The study is presented as relevant to identifying receptive areas and informing vaccination planning in affected and exposed populations. It also frames the findings as important for understanding outbreak spread in a region with long-term interruption of viral circulation.
Structured evidence summary
Research question
The article asks which mosquito species were associated with the major yellow fever outbreak in Brazil from 2016 to 2018, using entomological data collected before and during the outbreak.
Study design
This is a cross-sectional entomological survey with outbreak-era comparison. The authors examined mosquito distribution, abundance, and natural infection status across municipalities sampled before and during the outbreak.
Population and setting
The study was conducted in 44 municipalities across five Brazilian states, in the Atlantic Forest region of Brazil. The sampled population was mosquitoes, with 17,662 specimens from 89 species collected.
Main findings
The abstract states that Haemagogus janthinomys and Haemagogus leucocelaenus were the primary vectors, based on wide distribution, high abundance, and natural infection. It also reports first detection of infected Aedes taeniorhynchus and no evidence of transmission by Aedes albopictus or Aedes aegypti in the surveyed material.
Public-health relevance
The study is presented as relevant to identifying receptive areas and informing vaccination planning in affected and exposed populations. It also frames the findings as important for understanding outbreak spread in a region with long-term interruption of viral circulation.
Important limitations
No explicit study limitations are stated in the abstract. This summary is limited to the supplied single-article abstract and metadata, so the original paper is needed for decision-grade interpretation.
GIDS interpretation
The article is discoverable as a peer-reviewed outbreak investigation focused on yellow fever vectors in Brazil. The supplied abstract and metadata support contextual indexing for vector ecology and outbreak response, but this summary does not imply any live surveillance signal.
Related GIDS surveillance
Literature context does not validate, explain, or change a surveillance signal. Exact and contextual relationships are shown separately.
Evidence relationships
This article has 10 auditable classifier relationships to diseases, places, topics, and study design.
