Objective To review the scientific evidence about the impact of climate change and socio‐environmental factors on dengue transmission, particularly in the Asia‐Pacific region.
Methods Search of the published literature on PubMed, ISI web of Knowledge and Google Scholar. Articles were included if an association between climate or socio‐environmental factors and dengue transmission was assessed in any country of the Asia‐Pacific region.
Results Twenty‐two studies met the inclusion criteria. The weight of the evidence indicates that global climate change is likely to affect the seasonal and geographical distribution of dengue fever (DF) in the Asia‐Pacific region. However, empirical evidence linking DF to climate change is inconsistent across geographical locations and absent in some countries where dengue is endemic.
Conclusion Even though climate change may play an increasing role in the transmission of DF, no clear evidence shows that such impact has already occurred. More research is needed across countries to better understand the relationship between climate change and dengue transmission. Future research should also consider and adjust for the influence of important socio‐environmental factors in the assessment of the climate change‐related effects on dengue transmission.
Transmission de la dengue dans la région de l’Asie‐Pacifique: Impact du changement climatique et des facteurs socio‐environnementaux
Objectif: Passer en revue les preuves scientifiques de l’impact du changement climatique et des facteurs socio‐environnementaux sur la transmission de la dengue, en particulier dans la région de l’Asie‐Pacifique.
Méthode: Recherche de la littérature publiée sur PubMed, ISI Web of Knowledge et Google Scholar. Les articles ont été inclus si une association entre le climat ou les facteurs socio‐environnementaux et la transmission de la dengue a étéévaluée dans n’importe quel pays de la région de l’Asie‐Pacifique.
Résultats: 22 études répondaient aux critères d’inclusion. Le poids des preuves indique que le changement climatique est susceptible d’affecter la répartition saisonnière et géographique de la fièvre dengue dans la région de l’Asie‐Pacifique. Toutefois, la preuve empirique reliant la fièvre dengue au changement climatique n’est pas uniforme à travers toutes les régions géographiques et est absente dans certains pays où la dengue est endémique.
Conclusion: Même si le changement climatique peut jouer un rôle croissant dans la transmis |
