Why this research matters now
Ongoing vector proliferation and documented viral circulation indicate a growing regional burden that warrants coordinated monitoring strategies.
Structured evidence summary
Research question
What is the geographic spread of invasive Aedes mosquitoes and the current epidemiological landscape of dengue and chikungunya across Iran and surrounding nations?
Study design
Peer-reviewed narrative review compiling epidemiological data and vector distribution studies published between 2000 and the present.
Population and setting
Mosquito populations and human communities located within Iran and at least nine contiguous countries in the broader region.
Main findings
Both primary Aedes species are now established across multiple provinces in Iran and numerous neighboring states. Confirmed human dengue transmission occurred in several regional locations, while localized chikungunya activity was documented exclusively in Pakistan. Recent Iranian dengue clusters were geographically aligned with districts hosting Aedes aegypti.
Public-health relevance
Ongoing vector proliferation and documented viral circulation indicate a growing regional burden that warrants coordinated monitoring strategies.
Important limitations
The synthesis depends entirely on previously published literature and existing health records rather than original field investigations.
GIDS interpretation
This article functions as a contextual reference detailing historical vector ranges and past case reports. It offers background information useful for tracking regional disease patterns without reflecting active surveillance outcomes.
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 12 auditable classifier relationships to diseases, places, topics, and study design.
