Summary
Climate significantly impacts dengue virus (DENV) transmission by affecting mosquito traits and viral replication. Understanding these climate-DENV links is vital for managing the increasing global burden of this disease.
Area of Science:
- Environmental Science
- Epidemiology
- Vector-borne Diseases
Background:
- Climate variables influence the transmission dynamics of mosquito-borne diseases like dengue.
- Mosquitoes are key vectors for dengue virus (DENV), and their traits are sensitive to environmental conditions.
Purpose of the Study:
- To describe and evidence the intricate relationships between climate variables, mosquito traits, and DENV transmission.
- To highlight the importance of understanding these connections for disease management.
Main Methods:
- Review and synthesis of existing literature on climate impacts on mosquito biology and DENV.
- Analysis of the interplay between environmental factors, vector characteristics, and viral transmission.
Main Results:
- Climate directly influences mosquito physical and behavioral traits.
- Environmental factors affect DENV replication rates within the mosquito vector.
- Complex interactions between climate, mosquito traits, and DENV transmission are evidenced.
Conclusions:
- Understanding climate-DENV relationships is crucial for predicting and controlling dengue outbreaks.
- Global environmental change necessitates a deeper understanding of these ecological connections to mitigate rising DENV burden.

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
