Spatiotemporal expansion of Aedes aegypti and the dengue fever epidemic under climate change in China.

ABSTRACT:

Background

Aedes aegypti is the primary vector of dengue fever, a disease whose transmission is strongly dependent on warm, humid climates. While the geographical and seasonal patterns of dengue are well-established, systematic projections of how climate change will affect the distribution of Aedes aegypti and dengue transmission risk in China remain limited.

Method

We integrated a phenological model with a dynamical mathematical model to project the future distribution and population dynamics of Aedes aegypti under multiple Shared Socioeconomic Pathways (SSPs). We assessed life-cycle completion (LCC) intensity at the municipal level across China and simulated detailed mosquito population dynamics and dengue transmission in six representative cities under sustainable (SSP1-2
