“…Ecological backgrounds associated with WNV evidence status across the 2882 freguesias had properties in accordance with knowledge generated in previous studies. For example, ecological backgrounds with temperatures above 15 degree Celsius had a strong positive relationship with WNV presence ( Supplementary Text 1 ) 19,32 . In contrast, WNV presence was associated with backgrounds with lower precipitation, as also previously reported 33,34 .…”

“…Land type (e.g. rural, agricultural, forestry, wetlands and periurban) has previously been associated with mosquito abundance and WNV transmission 4 . Elevation data was downloaded from the EU-DEM v1.1 dataset, which has a resolution of 25m x 25m 5 .…”

“…Several dead-end hosts (mainly mammals) have been demonstrated to test positive for WNV infection. In addition, the presence of ovine, bovine and caprine farms within a 500 m radius from a mosquito trapping point has been considered a positive predictor for Culex pipiens abundance 4 . We thus considered the spatial distribution of several dead-end mammal hosts such as equine, caprine, bovine, swine, ovine, poultry and rabbits.…”

“…We observed a positive correlation between ecological suitability and temperature ( Figure ST3 ). Mean, minimum and maximum daily, weekly, monthly and annual temperatures have been demonstrated to be positively related to the abundance of mosquitoes, although not linearly, since abundance may be reduced at too high temperatures 4 (not observed on the temperature range of Portugal).…”

West Nile (WNV) is a zoonotic arbovirus with an expanding geographical range and epidemic activity in Europe. Not having yet experienced a human-associated epidemic, Portugal remains an outlier in the Mediterranean basin. In this study, we apply ecological niche modelling informed by WNV historical evidence (1969-2022) and a multitude of environmental variables from across Portugal. We identify that ecological backgrounds compatible with WNV historical circulation are mostly restricted to the south, characterized by a warmer and drier climate, high avian diversity, specific avian species and land types. We estimate WNV ecological suitability across the country, identifying overlaps with the distributions of the three relevant hosts (humans, birds, equines) for public and animal health. From this, we propose a category-based spatial framework providing first of a kind valuable insights for future WNV surveillance under the One Health nexus. We also forecast that climate trends alone will contribute to pushing adequate WNV ecological suitability northwards, toward regions with higher human density. This unique perspective on the past, present and future ecology of WNV addresses existing national knowledge gaps, enhances our understanding of the evolving emergence of WNV, and offers opportunities to prepare and respond to the first human-associated epidemic in Portugal.

Does land-use and land cover affect vector-borne diseases? A systematic review and meta-analysis

et al. 2023

Context Vector-borne diseases (VBD) are a worldwide public health problem for humans and wildlife. 'Global Change' such as habitat alteration and land-use intensification, biotic exchange, the introduction of invasive alien species, and climate change have all been linked to an increased occurrence of VBDs. Objectives To evaluate the impact of land-use and land-cover (LULC) on the transmission of VBDs, we conducted a systematic review of the existing literature on the global effects of land use on VBDs. This was followed by a meta-analysis to test the relationship between LULC intensification and infection prevalence. Methods Overall, 654 articles met our inclusion criteria for the systematic literature review, and 18 studies fulfilled the requirements for the meta-analysis. Results The systematic literature review identified 162 articles with a total of 2541 data entries on the effect of LULC on VBDs. The majority of the studies were published after 2010, and the spatial distribution of data was biased towards North America and Europe. Overall, 193 different hosts and 144 different vector groups were identified. Avian and human malaria were the most frequently named diseases, with humans and Anopheles mosquitoes the most common host and vector, respectively. Our meta-analysis found that land-use intensity, as well as targets (host and vector), significantly impact the prevalence of VBDs. Tests for both residual heterogeneity and moderators were significant, where lower land-use intensity and vectors were linked to lower VBD prevalence, while medium land-use intensity was associated with higher prevalence. Analysis of the host sub-model supported these findings, with infection prevalence significantly lower in low land-use intensity. Conclusions The systematic literature review revealed a temporal increase in publications on this topic, with a significant rise since 2007 and uneven distribution of data across countries, with the United States, Spain, and Brazil being the most prominent contributors and identified a wide range of pathogens and hosts involved in VBD systems, with human and avian malaria being the most commonly mentioned diseases. We also show, through a meta-analysis, that LULC intensification affects VBDs infection prevalence. Future studies should incorporate the effects of land-use intensity on vector-borne diseases in diverse ecosystems to inform management strategies and mitigate disease emergence with implications for human, livestock and wildlife health.
