Structural and spatial dynamics of mosquito-arbovirus associations in Mexico (2007 to 2025): A systematic review and quantitative synthesis

Wait 5 sec.

Background: Mosquito-borne arboviruses present persistent public health threats in Mexico. Multiple vector species are often considered to influence the local transmission of arboviral diseases; however, the structure and spatial dynamics of mosquito-arbovirus associations are unknown. Methods: We conducted a systematic review to synthesize research investigating natural arboviral infections across mosquito taxa. PRISMA-guided search was done in PubMed, Scopus, Web of Science and Google Scholar, resulting in 46 included articles from 2007 to 2025. To delineate mosquito-arbovirus associations, spatial autocorrelation, bipartite network analysis, generalized linear mixed models (GLMMs) and comparative analysis of infection across sex and life stages were used to resolve spatial dynamics, species-specific viral detection and maintenance profiles. Results: Minimum Infection Rate (MIR) revealed significant positive spatial autocorrelation (Global Morans I = 0.139; p = 0.016), indicating structured but diffuse spatial patterns (Local Morans I = 0.092; p = 0.045). Sampling intensity negatively correlated with the MIR (Spearman {rho} = -0.680, p < 0.001), indicating that sampling effort did not obscure the spatial structure. Elevated values were observed in a few municipalities across south-central and southeastern Mexico, where vegetation and land use interface. Network analysis (connectance = 0.40) and GLMM characterized an Aedes-centered network with broader taxonomic patterns driven by ZIKV; detection was significantly higher in Culex quinquefasciatus (OR = 1.88, p < 0.001) relative to Aedes aegypti. DENV detection patterns contrasted with other key viruses; no significant differences in transmission modes ({chi}{superscript 2} = 1.01, p = 0.315), suggesting a distinct maintenance profile. Conclusions: This review unveils spatially diffuse and virus-specific detection patterns across heterogeneous communities in Mexico, findings that transcend Aedes-centric frameworks. These resolutions provide an evidence-based baseline that encourages an integrated, community-scale approach in regional surveillance programs.
