The Temperature-Associated Effects of Rift Valley Fever Virus Infections in Mosquitoes and Climate-Driven Epidemics:...

Area of Science:

• * Virology
• * Vector-borne diseases
• * Climate change impacts

Background:

• * Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic disease affecting livestock and humans.
• * RVFV transmission depends on vector barriers influenced by genetics and temperature.
• * Climate change is a key driver of RVFV epidemics and geographic expansion.

Purpose of the Study:

• * To review recent advancements in understanding RVFV transmission dynamics.
• * To highlight the impact of temperature on RVFV-vector interactions.
• * To identify knowledge gaps concerning RVFV persistence and spread.

Main Methods:

• * Literature review of recent studies on RVFV, vector competence, and climate.
• * Analysis of temperature-sensitive variations in RVFV-vector interactions.
• * Discussion of demographic and weather pattern influences on RVFV conveyance.

Main Results:

• * Temperature significantly shapes RVFV evolution, replication, and spread by influencing vector barriers.
• * Microclimatic changes are linked to RVF outbreaks and expansion into new areas.
• * There's a need for more research on temperature's impact during interepidemic periods.

Conclusions:

• * Understanding RVFV-vector-environment interactions is crucial for disease management.
• * Further research is needed on temperature-dependent RVFV transmission and persistence.
• * Integrated strategies are necessary to address the growing RVFV disease burden.
